Solar eruptions in EUV

Over the last few weeks, some nice solar eruptions have been visible in the extreme ultraviolet passbands.

Quo vadis, magnetic pole?

The persistent movement of the North magnetic pole towards Siberia may have some consequences on local space weather impacts such as aurora visibility and geomagnetically induced currents.

X-class flare

After a drought of nearly 3 months, the Sun unleashed an X-class flare on 20 June.

SILSO change of management

SILSO logo

Due to a reshuffling of responsibilities, SILSO will from now on run under the single Directorship of Laure Lefèvre, and therefore any future questions related to the SILSO management or data should be addressed to Laure.Lefevre@oma.be.  We  take this opportunity to thank both Frédéric Clette and Laure Lefèvre for their dedication to the SILSO operations during many years.

ESA Academy visits the STCE

On May 8, the STCE team was invited to teach at ESA's Academy in Transinne (BE) in a pilot for their new Space Weather Training Course. 
30 students were selected for a week-long, in-depth school about space weather and its technological impacts. The STCE was responsible for giving the students a first introduction on how to forecast space weather events and impacts.


It's raining... CMEs!

The average daily number of coronal mass ejections (CMEs) was at high levels during the first 2 weeks of May.

Radio Sun!

A trio of sunspot groups in the northeast solar quadrant were responsible for an important portion of the solar flares produced early May. Some of these flares were accompanied by strong emissions at radio frequencies.
