The Solar-Terrestrial Centre of Excellence, STCE organises a space weather conference of world-class The European Space Weather Week, ESWW is THE annual event for researchers, users and others interested in Space Weather. The conference brings everybody concerned in contact with all possible aspect of space weather: from fundamental research to practical applications, from researcher to user. 300 participants worldwide chair their expertise and ideas. The conference is followed by politics, ESA, NASA and the public opinion.
Belgium and Europe, do attach importance to space weather. Our high technological society becomes even more vulnerable for the effects of space weather. Belgium provides one of the highest funds for the space weahter program of ESA.
Ronald Van der Linden, director of the Royal Observatory of Belgium and coordinator of the STCE is looking forward to the conference: “The ESWW guarantees a perfect and inspiring cocktail of science, products, information, formal and informal contacts. I’m proud on the fact that the STCE has a key role in the organisation and the success of this conference. It put Belgium on the space weather world map.”
Besides the actual conference and the focused workgroups, the ESWW offers a tutorial ‘Tour of Space’, a debate about space debris, the keynote lecture by Susan Jocelyn Bell Burnell, ... a juiced conference!
Het Solar-Terrestrial Centre of Excellence (STCE) organiseert een ruimteweer-conferentie van wereldformaat
De European Space Weather Week (ESWW) is de jaarlijkse hoogmis voor onderzoekers, gebruikers en geïnteresseerden in ruimteweer. De conferentie brengt alle partijen betrokken bij het ruimteweer in contact metalle mogelijke aspecten ervan: van puur onderzoek tot praktische toepassingen, van wetenschapper tot gebruiker. Onder het toeziend oog van de politiek, ESA, NASA en de publieke opinie, wisselen 300 deelnemers van over de hele wereld hun expertise en ideeën uit.
België en Europa hechten zeer veel belang aan ruimteweer, omdat onze snel evoluerende hoogtechnologische maatschappij steeds kwetsbaarder wordt voor de effecten ervan. België is dan ook één van de belangrijkste geldschieters van het ruimteweerprogramma van ESA.
Ronald Van der Linden, directeur van de Koninklijke Sterrenwacht van België en coördinator van het STCE, kijkt enorm uit naar de European Space Weather Week: “De ESWW staat garant voor een perfecte en inspirerende cocktail van wetenschap, produkten, informatie, informele en formele contacten.Ik ben dan ook fier op het feit dat het STCE een sleutelrol vervult in de organisatie en het succes van deze conferentie. Het heeft België verankerd op de ruimteweerkaart.”
Naast de eigenlijke conferentie en de specifieke werkgroepen voorziet het programma een tutorial ‘Tour of Space’, een debat over ruimteafval, een ‘keynote lecture’ door Susan Jocelyn Bell Burnell, ... Er valt dus zeer veel te beleven!
L’ European Space Weather Week (ESWW) est la grand-messe annuelle pour tous les scientifiques, les utilisateurs et les personnes intéressés par la météorologie spatiale. La conférence met en contact tous les acteurs et les différentes facettes de la la météorologie spatiale: du scientifique à l’utilisateur, de la recherche pure aux applications pratiques.

La Belgique et l’Europe attachent beaucoup d’importance à la météorologie spatiale, parce que notre société de haute technologie est de plus en plus vulnérable à ses effets. Ainsi, la Belgique est l’un des plus importants contributeurs financiers au programme de météorologie spatiale de l’ESA.
Ronald Van der Linden, directeur de l’Observatoire royal de Belgique et coordinateur du STCE, attend l’ European Space Weather Week avec impatience: « L’ESWW garantit un cocktail parfait de science, d’information, de produits, et de contacts formels et informels. Je suis fier que le STCE remplisse un rôle clé dans l’organisation et le succès de cette conférence. Cet événement annuel a ancré la Belgique sur la carte mondiale de la météorologie spatiale. »
En plus de la conférence et des groupes de travail spécifiques, le programme prévoit un tutoriel « Tour of Space », un débat sur les débris spatiaux, et un exposé inaugural par Susan Jocelyn Bell Burnell,... Cela ne manquera pas d’animation!
On October 23, active region NOAA1598 produced the 15th X-class flare of the current solar cycle (SC). The X1.8 was of short duration, lasting only 8 minutes. It did not produce an energetic particle event (proton event), and there was no obvious indication of an ejected plasma cloud.
NOAA Active Region 1598 produced an M5.0 flare on Oct 22, peaking at 18:51UT and an X1.8 flare on Oct 23, peaking at 03:17UT. There was no coronographic evidence for an associated plasma eruption. The proton fluxes did not increase.
Further nothing new under the Sun: only a few C-flares.
Cactus sent out two halo CME-alerts. The first one concerned a filament eruption on Oct 26, around 10:00UT in the South-East part of the solar disk. The CME was not Earth directed. The second one concerned an event of Oct 27. The CME came into the field of view of SOHO/LASCO at 16:00UT. SDO/AIA 192 shows a coronal dimming in the neighborhood from NOAA AR 1600. No flare was associated with the event. The estimateded speed of the CME was only 288 km/s. The CME was first accelerated as seen from STEREO/COR2 speed calculator tool at http://www.sidc.be/cactus.
Geomagnetic conditions were quiet the whole week: the solar wind speed stayed well below 400 km/s and a total interplanetary magnetic field below 5nT. A coronal hole present in the northern hemisphere reached the central meridian on Oct 24. The solar wind emanating from this hole didn't reach the Earth.

The propagation behavior of coronal mass ejections (CMEs) in interplanetary (IP) space is mainly influenced by the ambient solar wind flow. The interaction of CMEs with the solar wind can be expressed as drag force and manifests itself to decelerate CMEs that are faster than the ambient solar wind, whereas slower ones are accelerated until the CME speed is finally adjusted to the solar wind speed. With the SECCHI instrument suite aboard STEREO, CMEs can be observed during their entire propagation way from Sun to 1AU. The derived kinematical profile and its changes may be interpreted as interaction with high speed solar wind streams as well as other coronal mass ejections.

A one-day session and workshop was held on the subject of Geomagnetically Induced Currents (GIC) in electrical power networks at the 8th European Space Weather Week, in Namur, Belgium, on 30th November 2011. We describe the questions that were posed at the workshop and summarise the outcomes of the discussions. Among the conclusions reached were the need for improved Sun to Earth numerical models and the need for continued national and international support for space weather monitoring missions and ground networks of instruments. It was also concluded that there was much scope for improved national and international responses to space weather warnings and the need for collaboration between scientists, industry and governments to achieve this.

international partnership of Europe, North America and East Asia in
cooperation with the Republic of Chile, is the largest astronomical
project in existence.
The workshop aims to bring together the ALMA-minded solar
community to discuss solar observational issues with ALMA, solar
science and planned observations with ALMA, and the planning of
solar ALMA observations.
Th workshop is hosted by Astronomy & Astrophysics Group,
and will take place in School of Physics and Astronomy, University
of Glasgow, Room 323, Kelvin Building.

Helioseismology provides tools for imaging structures and mass
flows below the solar surface, and is becoming an essential
technique for understanding the dynamics of solar activities and
developing physics-based forecasts of the solar cycle, emerging
active regions and energy release events. A better understanding is
needed to unravel the effects of the complex interactions of solar
oscillations with the turbulent magnetized plasma
on global and local helioseismology
diagnostics. These effects are particularly challenging in regions
of strong magnetic fields. Numerical simulations of solar MHD waves
and turbulent dynamics give important insights into the complicated
wave and turbulence physics, and provide synthetic data for
verification and validation of helioseismology methods and
results.
The goals of this workshop are to discuss and stimulate further
development of helioseismology methods, solar interior models, and
realistic numerical simulations. These goals are particularly
important for analysis of the continuous data flow from the Solar
Dynamics Observatory, development and verification of
helioseismology methods, and for theoretical interpretation of
observations and inversion results.

The most recent solar minimum, solar cycle 23-24 minimum, was
unusually long (266 spotless days in 2008, the most since 1913),
and the magnetic field at the solar poles was approximately 40%
weaker than the last cycle; and unusually complex (the solar wind
was characterized by a warped
heliospheric current sheet, HCS, and fast-wind
streams at low latitudes: the
fast-wind
threads the ecliptic
more commonly in 2008 than 1996.)
This complexity resulted in many effects observed from Sun to
Earth, with many observations indicating unusual conditions on the
Sun, in the heliosphere
, and in the magnetosphere
, ionosphere
, and upper atmosphere of the
Earth.
This remarkable set of conditions provide the scientific
community with an exceptional opportunity to assess the nature and
structure of a very quiet Sun, and an upper atmosphere relatively
devoid of solar influences, helping to provide a better
understanding of the relative roles of solar activity and internal
variability in the dynamics of the Earth's upper atmosphere and
ionosphere
. Such an understanding requires a
multidisciplinary approach.
The main goal of the conference is to bring together the solar,
heliospheric, magnetospheric, upper atmosphere, and ionospheric
communities to debate and discuss interdisciplinary work and reach
a better understanding of the nature and structure of a very quiet
Sun, and of an upper atmosphere relatively devoid of solar
influences, and in doing so, to help clarify the role of solar
activity in the dynamics and variability of the Earth's upper
atmosphere and ionosphere
relative to the internal
variations.

In the last 50 years, helioseismology has made significant
contributions to the knowledge of the Sun's interior physics
and has led the way to asteroseismology. We have now reached an era
where more sophisticated questions are being asked to understand
the subtle properties of the Sun and other stars due to the
synoptic and high-resolution observations available from BISON,
GONG and space missions such as SOHO
, SDO, CoRot and Kepler.
On this occasion, a workshop on the theme of '50 years of the
seismology of the Sun and stars' is being organized to reflect the
progress that has been made as well as to focus on future goals. We
plan to bring together helio- and asteroseismologists, theorists
and observers in a journey that will take us from the interior of
the Sun and its magnetism towards the structure of distant stars
and activity cycles.

The Summer School Alpbach enjoys 36 years of tradition in
providing in-depth teaching on different topics of space science
& technology, featuring lectures and concentrated working
sessions on mission studies in self-organised working groups. 60
young highly qualified European science and engineering students
converge annually for stimulating 10 days of work in the Austrian
Alps. 4 teams compete to design a space mission judged by a jury of
experts. Students learn how to approach the design of a satellite
mission and explore new and startling ideas supported by experts.
The Summer School 2013 will focus on Space Weather
.
The purpose of the Summer School is to foster the practical
application of knowledge derived from lectures, to develop
organisational and team-work skills and to encourage creativity.
Teams will compete to design the best project, judged by an
independent jury. The teams themselves are responsible for the
selection of the subject of the project and for the team structure
and working methods.

We gain information about the universe through analysis of the
spectra from celestial objects. However, while the intensity
spectrum represents a scalar quantity but electromagnetic radiation
occurs in the form of transverse waves, the polarized spectrum
provides us with a 4-vector, the Stokes vector. The increased
amount of information space opens new windows to the universe, in
particular for the exploration of magnetic fields. It is well
recognized that the magnetic field is a primary agent responsible
for structuring and the source of all variability on intermediate
time scales, which manifests itself in all forms of solar and
stellar activity.
It is therefore not surprising that every year there are many
scientific meetings organized with the objective of studying the
role of magnetic fields in cosmic objects. What is largely missing
in these meetings is however an in-depth investigation of the
fundamental aspects of how magnetic fields can be determined by the
means of spectro-polarimetry, our main gateway to cosmic magnetism.
The primary aim of our series of Workshops is to address these
fundamental aspects, with less emphasis on the morphological and
physical properties of cosmic magnetic fields.
