10 - Open session on Space Weather Applications and Engineering Concerns
Alexi Glover and the ESWW11 Program Committee
This session targets the wide range of application
development currently ongoing in Europe and abroad. This includes a broad range of application types including algorithms and applications designed
to nowcast and forecast space weather conditions in space or on ground, analysis toolkits and supporting data(base) infrastructure developments.
The session is open to well established applications
which are already operating as (prototype/precursor) services, newly developed applications and proof of concept demonstrations.
Submissions covering tailored applications are particularly encouraged which include a discussion of how the author
has worked with a potential/existing service user in order to address specific engineering concerns.
In all cases, authors are strongly encouraged to address validation, describe the approach used to assess (anticipated)
application performance and to outline their vision and/or experience of how users might take action in response to the output of
their application.

Royal Netherlands Air Force's
(RNLAF) Joint Meteorological Group (JMG) aims to link space weather knowledge
and products of experts (SIDC/SWPC) to operational end-users in our defence
organisation, e.g. special forces, signals officers, pilots and navy officers. They ask for plain and simple forecasts on
operational impact. We find these hard to give, as there aren't many solid
"dose-response relationships" for space weather effects.
Furthermore they are receptive though skeptical. To achieve our goal we raise their
awareness by providing heads-ups during flares and storms and performing
pilots. Hereby we try to remove some skepticism and induce feedback which we
need to improve our operational impact forecast. During my talk I will sketch our road map
by an anthology of our actions and the questions they raise. |

The Global Ionospheric Flare
Detection System (GIFDS) of the DLR consists of a ground-based network of VLF
receivers (Perseus SDR - Software Defined Radio), which provides signal
strength and phase measurements at multiple frequency channels from 10 to 60
kHz. One of the main objectives of GIFDS is the immediate and continuous
detection of solar flares as a result of their impact on the bottomside
ionosphere and consequently their sudden effects on VLF signals. As such
events can only be detected during daytime, DLR is installing a uniform set
of receivers at selected locations around the world. Measurements carried out
at the dayside sector will be provided 24/7 in the near future. VLF
measurements not only contain information about the direct impact of solar
flares but also depend on solar irradiation and geophysical conditions.
Regarding the latter, the impact of diurnal variations on VLF signal strength
can be minimized by means of a time series analysis and a subsequent
detrending of the records. Thus, a robust polynomial curve fitting is applied
in order to determine diurnal variations for flare separation. Subsequent
measurements are regularly adjusted by compressing, stretching, rotating and
shifting the basic approach to ensure a stabilized output. In conclusion,
results are compared with X-ray measurements onboard GOES satellite to
validate flare detection concerning size and shape. |

Automated detection and
prediction is an important ingredient to achieve 24/7 space weather
operations. We present and assess a new service for automated detection and subsequent
classification of solar wind disturbances arriving at L1. Focus is on
disturbances with a potential for creating geomagnetic storms. The service requires solar wind in situ
plasma and magnetic field observations, currently provided in near real-time by
NOAA/NASA from the ACE SWEPAM and MAG instruments. Periods of significantly
enhanced magnetic field are identified and classified according to their most
likely cause, being either propagating interplanetary coronal mass ejections
(ICMEs) or high speed streams creating stream interaction regions (SIRs). In
the output the disturbed intervals are thus classified either as “ICME”
related, “SIR” related or “NO ID”. The latter occurs when the classification
criteria are either not fulfilled or only partly fulfilled and/or both some
ICME and SIR criteria applies. We
compare the results with existing lists of ICMEs and SIRs derived manually,
and assess the usefulness of the service for providing early warnings of upcoming
geomagnetic storms. |

A new ESA activity is underway
to establish a Data Browsing and Quick Look Service. The primary objective of
this task is to develop an easy-to-use interface and preliminary set of
visualisation tools - the SWTK - supporting a forecaster in rapid analysis of
latest space weather data. It will also support general public interest and
understanding in space weather events. The SWTK will support the co-analysis
of both numerical time-series data and contextual products – for example,
images, model results, alerts, reports and forecasts, and user-generated
content – by using two distinct
software libraries. The numerical
data will be imported from the SSA-SWE Data Centre into a Charting library to
provide the User with state-of-the-art display, analysis and manipulation
tools for real-time and historical data. The products will be imported into a
Timelining tool that will allow the User to place the measurements alongside
a range of supporting contextual items to assess the full development of the
event and forecast the likely impacts.
The development of SWTK is supported by the European Space Agency (ESA
Contract: No. 44000105734/12/D/MRP). |

The aim of ESPAS Research
Infrastructure is to facilitate the access to data from the near-Earth space
environment (http://www.espas-fp7.eu). ESPAS envisages creating a one-stop
shop for researchers and users of research results who wish to exploit multi-instrument
multi-point science data for analysis, model building, data assimilation into
models, model-observation comparison, space environment nowcast and forecast,
to name just a few. The ESPAS project
has entered its third year of activities, with a set of tools to support
standards and interoperability, deployed in the main platform and the data
nodes. Main elements are the data model, which is compatible with all
heterogeneous data formats, the XML schemas for metadata exchange format, the
domain-specific ontology, the wrapper installed at the data nodes to support
metadata harvesting from the main platform, the main platform built on the
D-NET framework and the GUI with its designed workflows. The current release
provides access to the majority of datasets registered in ESPAS from ground
based Digisondes and ionosondes, magnetometers, GNSS receivers, Fabry Perot
Interferometers, SUPERDARN, ISRs, and from space missions CHAMP, IMAGE/RPI,
ACE, SOHO, PROBA2, NOAA/POES, DEMETER, Cluster, ISIS/Alouette, MAGION3, among
others. In order to enhance its functionalities, ESPAS will provide datasets
derived from a number of models such us IRI-2012, EDAM, CMAT2. This presentation aims at providing an
overview of the system functionality and to present some indicative science
cases that ESPAS can support to enhance space weather applications. |

The Community Coordinated
Modeling Center (CCMC) at NASA Goddard Space Flight Center enables, supports,
and performs research and development for next generation space science and
space weather models. The CCMC currently
hosts a large and expanding collection of state-or-the-art, physics-based
space weather models that have been developed by the international research
community. There are many tools and
services provided by the CCMC that are currently available world-wide, along
with the ongoing development of new innovative systems and software for
research, discovery, validation, visualization, and forecasting. Over the history of the CCMC's existence,
there has been one constant engineering challenge - describing, managing, and
disseminating data. To address the
challenges that accompany an ever-expanding number of models to support,
along with a growing catalog of simulation output - the CCMC is currently
developing a flexible and extensible space weather data warehouse to support
both internal and external systems and applications. This paper intends to chronicle the
evolution and future of the CCMC's data infrastructure, and the current
infrastructure re-engineering activities that seek to leverage existing
community data model standards like SPASE and the IMPEx Simulation Data

The EU co-funded project
SPARC analysed the relation existing
among Space Threats (Space Weather, Space Debris and Near Earth Objects) and
the capabilities of the Critical Infrastructures to continuously supply their
services, considering risks, exposures and countermeasures. Critical
Infrastructures (CI), which include Energy Grid, Telecommunication network,
Transport Systems, etc. are today the backbone of modern societies.
Originally designed separately, they now work through a high-level of
interdependency among each other, composing a very complex system of systems,
extended from the ground to the near space. Therefore, a single failure, due
to a generic threat, could potentially trigger a “domino effect” with
unpredictable and severe impacts. In this framework, also due to the
pervasive use of ICT and GNSS services, Space Weather can represent a serious threat able to impact on CI
operational capabilities in a wide and diffuse way and at different levels,
producing negative consequences which also involve stakeholders unaware of
their vulnerability. It is fundamental to foresee the behaviour of the whole
system of systems in particular scenarios, considering both the direct
effects that space weather may have on CI but also the indirect consequences
induced by the presence of interdependencies. Indeed, only in this way we can
have a clear vision of the potential consequences in order to define
mitigation strategies. To this end, in the SPARC project the impact of Space
Weather on CI has been investigated through CISIA simulation framework.
Specifically a complex scenario composed by urban areas and related electric,
transportation and communication networks has been considered going to
analyse the impact of a severe solar storm in terms of direct consequences
but also considering the indirect effects induced by degraded GNSS services.
CISIA Simulation is surely a kind of countermeasures. On the other hand,
SPARC results highlighted that countermeasures need to include early warning
services, based on improved nowcasting and forecasting capabilities.
Telespazio, in cooperation with the scientific community, is working to
develop an operative Space Weather Early Warning service. |

The awareness about potential
major impact geomagnetically induced currents (GIC) can have on the North
American high-voltage power transmission system has prompted Federal Energy
Regulatory Commission (FERC) to launch a geomagnetic disturbances (GMD) standards
drafting process. The goals of the GMD standards are to quantify and mitigate
the GMD hazard on the North American grid. North American Electric
Reliability Corporation's (NERC) is coordinating the standards drafting
process that is now entering Phase II involving quantification of the impact
GIC can have on individual parts of the North American grid. As a part of the Phase II GMD standards
drafting process, substantial effort has been made for generating benchmark
GMD scenarios. These scenarios that quantify extreme geoelectric field
magnitudes and temporal waveforms of the field fluctuations are the
foundation for subsequent engineering and impacts analyses. The engineering
analyses will include the transmission system voltage stability and
transformer heating assessments. The work on the GMD scenarios has been a
major collaboration between a number of international entities involved in
GMD research and transmission system operations. We will discuss in this
paper the key elements of the benchmark GMD generation process and show the
latest results from our work on the topic. |

Geomagnetic disturbances can
cause potentially damaging geomagnetically induced currents to flow through
the long conducting lines of the United States bulk power system. This goal
of this project is to provide tools that allow transformer operators a better
understanding of the geophysical hazard due to GICs. This is done through the
combination of publicly-available data, information specific to a utility’s
local area, and newly-developed models for electric field calculation. Public
resources include data available through federal and academic magnetometers,
and wide-area regional conductivity profiles of the physiographic regions of
the US. Proprietary and regional
resources are added to increase the accuracy of a local specification for an
individual customer, and may include: local magnetic field information from
measurements or models, locally-targeted conductivity estimates and
measurements, and measured neutral currents from specific transformer assets.
These data are incorporated into wavelet-based electric field estimation
models using frequency-separated interpolation to produce accurate estimates
of the geophysical hazard at locations distant from direct measurements. We
present a prototype geo-electric field hazard map product and show
preliminary validation work for the newly-developed wavelet-based techniques. |

The SWENET archive was initially
developed as part of the ESA Space Weather Applications Pilot Project,
starting in 2003. The Pilot Project supported the development of a network of
prototype space weather services, many of which are still active and have
been developed further in the intervening time. SWENET was established as the
common access portal and data repository for these services, providing a
series of analysis tools and added functionalities to both service developers
and users. SWENET gives users access
to a wealth of space weather data and products that cover ground, Ionospheric
and spacecraft effects. The archive has stored information since 2003 and was
redeployed in Redu in 2010 as part of the SSA preparatory phase, currently
housing a large amount of data from 20 different providers. This year the
SWENET interface has been upgraded having been replaced by the new data
browsing and analysis functionality on the SWE web portal ‘DC-ll’. DC-ll has
ingested the original SWENET data which can all be manipulated in an improved
analysis environment. As part of the
initial SWENET development a set of preliminary metrics, or index quality
statistics, were provided as an additional service via the SWENET web portal.
The objective of this project is to review the database and revisit the
existing metrics with a view to assessing the performance of a number of the
original prototype services. Understanding the strengths and limitations of
these forecasts ensures a reliable service to the end user. As an initial case study, we have selected
two services which forecast geomagnetic indices and/or data for analysis, namely
the BINCASTS and GIFINT (Dst forecast).
We have assessed the corresponding data in the SWENET archive using a
selection of metrics that are currently in use by the space weather and
meteorology community. Appropriate metrics to each service have been used to
compare the model performance to actual observations, helping to identify and
evaluate the strengths and weaknesses of each model. |

A solar flare is a sudden and
intense brightening on the photosphere as a result of a conversion of
magnetic energy into heat and radiation. Currently, GOES X-Ray Flux is used
to classify the intensity of these powerful space weather events; however,
GOES data is limited to the Earth facing half of the Sun. We will investigate
and develop the use of NASA’s Solar TErrestrial Relations Observatory’s
(STEREO) Extreme UltraViolet Imager (EUVI) as a proxy for GOES X-Ray Flux to
fully understand solar flares across the entire Sun. The low cadence and
image resolution of the beacon data, along with the lack of large flares
during the early operational stages of STEREO limit our ability in finding a
strong correlation between the two instruments. We also use the higher
resolution and shorter cadence Science Data from STEREO to understand the
necessary requirements for an operational, realtime proxy to be possible. |

Polar Cap (PC) index now
IAGA-endorsed |
|

Stauning, P |

Danish Meteorological
Institute |

|
|
A new polar Cap (PC) index
version has now been endorsed by the International Association for
Geomagnetism and Aeronomy (IAGA) at the General Assembly held in 2013. The PC
indices, scaled to equal the merging electric field in the solar wind,
represent the conditions that dominate the solar wind interaction with the
magnetosphere. The PC indices, PCN based on Thule magnetic data and PCS based
on Vostok data, are the firsts among the ground-based indices to respond to
changes in the solar wind forcing of the magnetosphere. Most other ground-based indices, e.g., the
auroral electrojet index AE (or AL), the Kp index, and the ASY-H index could
be derived directly from the PC index with time delays of around 5-15 min. The
ring current index, Dst, can be derived by integration of the PC index.
Further indices or parameters like the Auroral Power index, the Electrojet
Joule heating, and the Cross Polar Cap Potential could be associated
statistically with the PC indices. Thus, the PC indices are extremely useful
in Space Weather forecast and analyses.
Unfortunately, there are still some unresolved issues around the new
PC index version. It uses in its derivation procedure an “effective” Quiet
Day level (QDC) composed of a basic QDC and an added solar wind sector
contribution related to IMF By. The IMF By-related contributions are derived
from daily median values of the magnetic variations and may in some cases
improve the PC index by a few tenths of a unit (mV/m) at midday while
introducing unfounded contributions of up to 2 units (possibly even more)
during the night and morning hours (substorms onset at PC~1.5 unit).
Furthermore, during cases of strong northward interplanetary magnetic fields
(IMF Bz>>0) the transpolar ionospheric convection and the associated
magnetic variations are often opposite (reverse) of the usual forward
convection and could be quite strong. The proportionality between the
magnetic variations and the geo-effective (or “merging”) solar wind electric
field, which is assumed in the definition of the polar cap index, breaks
down. It is argued here with illustrative examples, that the reverse
convection cases should be excluded in the calculation of the regression
coefficients used to derive PC index values from geomagnetic variation data. |

The main idea of the IMPEx FP7
project is to integrate the satellite measurements and simulation data, which
are obtained from multiple sources (satellite measurements and simulation
data bases, on-line calculating services, all kinds of data providers),
within one digital framework, so that all sorts of tools and applications
would have unified access to the data. Paraboloid model (PMM), which
represents the electrodynamics processes in the Earth’s magnetosphere, is a
part of this infrastructure. This model is intended to calculate the magnetic
field generated by a variety of current systems located on the boundaries and
within the boundaries of the Earth’s magnetosphere under a wide range of
environmental conditions, quiet and disturbed, affected by Solar activity
such as Solar Flares and related phenomena. A set of Web-services to provide
the access to PMM calculations and to enable the modeling data
post-processing under SOAP protocol have been created. 3D visualization tool
allows represent the output of PMM-related web-services, such as magnetic
field line calculation, magnetic field along the spacecraft trajectory, etc.
Data for the input parameters of the web-services can be fetched from the
local Oracle data base or inserted manually. Spacecraft trajectories are
fetched via the AMDA’s IMPEx web-service. The communication between the
in-browser visualization tool and the IMPEx web-services is based on the SOAP
protocol and is defined by the web-service interface, which is described in
the relevant .wsdl file. The graphics itself is written on the WebGL
language. The real-time model of the Earth's magnetosphere is currently
working at SINP MSU Space Weather Web-site. |

ESA's Space Environment
Information System (SPENVIS) is an on-line resource for evaluating the space
environment and its effects on spacecraft components and space
travellers. The system, developed by
the Belgian Institute for Space Aeronomy (BIRA-IASB) in 1996, has been
operational for more than fifteen years and has a mature international user community of about 10000 registered
users around the globe. SPENVIS is used for various purposes like mission
analysis and planning, education, and running models for scientific
applications. Within the ESA/GSTP-5
programme, a next generation of this resource is in development. The
framework and models of the SPENVIS system are reviewed, restructured and
reengineered using current web design techniques and programming
methodologies, providing a new, extensible and open framework for the
integration of current and future space environment models. In this poster we present the current
status of the new system and discuss it main features. |

The CME Geomagnetic Forecast
Tool (CGFT) is one of the forecast tools implemented in the COMESEP alert
system, an automated space weather alert system developed within the FP7
project COMESEP running since January 2014 at http://comesep.eu/alert/. The
CGFT provides an estimation of the CME arrival probability and its likely
geoeffectiveness, based on CME parameters, as well as an estimate of the
geomagnetic-storm duration. More specifically, CME geoeffectiveness is
estimated based on the CME width and speed, source position and X-ray class
of the associated flare and expressed using Disturbance storm time (Dst)
index. The CGFT was “fine-tuned” to the automated detection tools used in the
COMESEP alert system, namely CACTus (CME detection), Solardemon, and
Flaremail (flare detection). Furthermore, additional analysis of the
statistical properties of CME geoeffectiveness was performed in order to
improve threshold values for the different Dst storm levels. We compare these
changes to the estimations provided by already issued alerts and evaluate CME
geoeffectiveness forecast on an independent sample. This work has received
funding from the European Commission FP7 Project COMESEP (263252), “Dynamics
of the Solar System” association’s research grant (at Royal Observatory of
Belgium), and Croatian science foundation. |

Abstract: As part of the FP7
SOLARNET project a new Solar Virtual Observatory (SVO) is being developed at
the Royal Observatory of Belgium. The goal of the SVO is to make data from
European ground based telescopes such as GREGOR, SST, THEMIS, VTT, DST as
well as data from space missions such as
SDO and PROBA2 easily available to the scientific community. Our aim
is to make the SVO user friendly while also providing advanced options for
more in depth searches. In order to accomplish this, we are working on
refining FITS standards for Solar data and meta-data. Our e-poster will
showcase the SVO web interface through various search examples. |

"How far south will the
aurora borealis be seen?" is a common question asked when a geomagnetic
storm forecast is issued. It is not a straightforward answer; and current
projections based, for example, on Kp do not always match sighting reports
received after a display. Citizen science - engaging the general public to
aid scientific research - may be one way of tackling this issue. By using social media, such as Twitter, a
new source of data can be mined for scientific analysis. We present a new interactive web
application to gather relevant tweets about the aurora and display these on a
map. This tool has been created in JavaScript using the Twitter API and a
customised application template from ESRI. We use both active and passive
means to gather data. We actively encourage users to tweet using a known
hashtag (#BGSaurora) with their location in a prescribed format. This will
geo-locate the tweet and place a marker on the map reporting the sighting. We
can also passively search tweets for more general hashtags such as #aurora or
#northernlights. If these are geo-tagged they again can be mapped. Other
relevant data layers, such as cloud cover and geomagnetic activity levels,
can also be displayed. We present the
aurora sightings map and discuss the benefits of it both as an application to
engage the general public, helping them to see when and where aurora are
visible, and as a potential tool for gathering useful data for scientific
analysis. If a better indicator of geomagnetic activity levels relevant for
aurora viewing can be determined from these then this in turn will improve
future predictions for aurora enthusiasts. |

The Regional Auroral Forecast
(RAF) system which is currently under development in the ESA SSA programme
will provide its users with nowcasts and forecasts of auroral activity and
cloudiness in the Fennoscandian sector. RAF relies on the same empirical relationship
between auroral sightings and magnetic field time derivative values which is
used in the Auroras Now service (http://aurora.fmi.fi) developed in the ESA
Space Weather Applications Pilot Project as part of the SWENET network of
Service Development Activities. Experiences gathered in this service show
that in 85% of the cases when alert has been given also auroras were
observed. The new RAF system uses Near Real Time (NRT) magnetic field
measurements from five stations under the auroral zone for creating auroral
nowcasts on maps where also statistical auroral oval according to current Kp
value is shown. In addition, during auroral season in night time the service
shows auroral camera images from four stations. Cloudiness predictions are
provided by the weather forecast service of the Finnish Meteorological
Institute. Forecasts on auroral
activity in RAF are based on statistical relationships between data sets
which describe solar and global activity and magnetic time derivative values
recorded in the RAF magnetometer stations. In our approach the solar and
global activity is characterized with NRT alerts by NOAA, Halo-CME alerts by
SIDC and with FMI alerts for enhanced magnetic variability based on ACE data.
Ten year data sets (2002-2012) were used for NOAA alerts, Halo-CME alerts and
time derivative values, while for FMI/ACE alerts data from years 2010-2011
(18 months) were used to construct the statistical relationships. The integration of the RAF system in SSA’s
SWE Portal, following the principles of Service Oriented Architecture, has
enabled to reuse existing software services. This approach has demonstrated
the extensibility and adaptability of the architecture, leading to reduced
risks and shorter implementation times.
In the presentation we will describe the details of RAF system and
discuss the challenges in the attempts to make reliable auroral forecast with
more than one hour lead times. |

We present an integrated
software library dedicated to the analysis of time series recorded in space
and adapted to investigate turbulence, intermittency and multifractals. The
library is written in MATLAB and provides a graphical user interface (GUI) customized
for the analysis of space physics data available online like: Coordinated
Data Analysis Web (CDAWeb), Automated Multi Dataset Analysis system (AMDA),
Planetary science archive (PSA), World Data Center Kyoto (WDC), Ulysses Final
Archive (UFA) and Cluster Active Archive (CAA). Three main analysis modules
are implemented in INA: Fourier, Wavelet and PDF analysis. The layered
structure of the software allows the user to easily switch between different
modules/methods while retaining the same time series for the analysis. The
Fourier analysis module includes algorithms to compute and analyze the Power
Spectral Density (PSD) and the Spectrogram. Wavelet analysis includes
algorithms to compute the Scalogram, the Local Intermittency Measure (LIM)
and the Flatness parameter. The PDF analysis module includes algorithms for
computing the PDFs for a range of scales and parameters fully customizable by
the user; it also computes the Flatness parameter and enables fast comparison
with standard PDF profiles like, for instance, the Gaussian PDF. The
integrated software library has been tested on several Cluster and Venus
Express data and we will show relevant examples. Parts of the library were
also used to systematically analyze solar wind and planetary data within the
STORM FP7 project (Solar system plasma Turbulence: Observations,
inteRmittency and Multifractals). Image catalogues of the results are
available through the project website at http://www.storm-fp7.eu/. Research supported by the European
Community’s Seventh Framework Programme (FP7/2007-2013) under grant agreement
no 313038/STORM, and a grant of the Romanian Ministry of National Education

An important objective of the
Community Coordinated Modeling Center (CCMC) is to prototype, validate, and
compare various space weather environment forecasting methods. As such, CCMC
has developed three CME specific tools with the goal of facilitating advanced
analysis and collaboration within the space weather community. The three
tools we highlight in this paper are: Stereo CME Analysis Tool (StereoCAT),
WSA-ENLIL-Cone Fast Track, and Space Weather Scoreboard. These three tools
allow making CME measurements, executing custom space weather model runs, and
providing a systematic way for the scientific community to record and score
predictions and forecasts both prior to, and after CME arrivals at 1 AU. By using our Stereo CME Analysis Tool
(StereoCAT), scientists can quickly calculate CME kinematic properties. With
a few mouse clicks, StereoCAT triangulates between satellite imagery
(StereoA, StereoB, SOHO) to calculate CME direction, speed and opening angle. In addition to single measurements,
StereoCAT can create an ensemble of measurements. The derived CME parameters can subsequently
be used by the scientist in either their own models, or they can be entered
into the WSA-Enlil-Cone Fast Track tool, which will execute a custom
simulation based on the parameters produced by StereoCAT. WSA-Enlil-Cone Fast
Track is a quick and easy way to have CCMC perform your WSA-Enlil-Cone model
run. Just enter a few parameters, and
the model run is automatically executed within CCMC’s dedicated high
performance computing infrastructure.
The end result is a set of arrival time predictions along with
corresponding visualizations that illustrate the critical characteristics of
the CME such as size and the projected impact path. Forecasters can then take the results from Fast Track and enter
them into the Space Weather Scoreboard. The space weather scoreboard is a
research-based forecasting methods validation activity for CME arrival time
predictions which provides a central location for the community to: submit
their forecast in real-time, quickly view all forecasts at once in real-time,
and compare forecasting methods when the event has arrived. All types of prediction models and methods
are welcome from the world-wide research community for inclusion in the space
weather scoreboard, and there are currently 17 registered CME arrival time
prediction methods. Users submit their predictions for ongoing CME events and
most importantly can provide detailed descriptions on how their prediction
was made from the model, i.e.. method, input parameters. Members of the research community can then
view all of the predictions, modeling details, and the ensemble average of
all predicted arrival times submitted by the community. The space weather scoreboard enables
world-wide community involvement in real-time predictions and ultimately will
help researchers improve CME arrival time forecasting and understanding CME
propagation. |

A project is initiated at the
IAASARS of the National Observatory of Athens (NOA). Its main objective is to
develop techniques in order to provide forecasting tools in support of space
environment services. The objective will be achieved through: a) the operation
of a small full-disk solar telescope to conduct regular observations of the
Sun in the Ha line; b) the construction of a database with near real-time
solar observations which will be available to the community through a server
(HELIOSERVER); c) the development of an interface between the DIAS system
(the European Digital Upper Atmosphere Server) and the HELIOSERVER and
subsequently the enhancement of the DIAS database with metadata from solar
observations; and d) the upgrade of ionospheric forecasting models
implemented in the DIAS system for the real-time quantification of the
effects of solar eruptive events. The project is funded through the
KRIPIS/PROTEAS programme of the Greek Secretariat of Research and Technology. |

Geomagnetic storms are known to
cause geomagnetically induced currents (GICs) which can damage or destroy
transformers on power grids. Previous studies have examined the vulnerability
of power networks in countries such as the UK, New Zealand, Canada and South
Africa. Here we describe the application of a British Geological Survey (BGS)
thin-sheet conductivity model to compute the geo-electric field from the
variation of the magnetic field, in order to better quantify the risk of
space weather to Ireland's power network. As part of a near-real-time warning
package for Eirgrid (who oversee Ireland's transmission network), severe
storm events such as the Halloween 2003 storm and the corresponding GIC flows
at transformers are simulated. |
