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.

Over the last 2 weeks, some sizeable sunspot groups were visible with the (protected) naked eye.

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.

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.

Active region NOAA 3288 developed a delta magnetic configuration that resulted in increased flaring activity, culminating in a M7.1 flare on 1 May.
