An important milestone was achieved mid-June when the mount and parabolic reflector were installed for the Open Access Radio-Telescope project

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.

There was quite the excitement in USET team last week. Not one, but two sunspot regions were visible with the naked eye!

Ground based optical and radio solar instruments from ROB monitor together the recent period of increased solar activity

The EUI telescope on Solar Orbiter was able to catch the miniature version of solar flares and mass ejections. Thanks to sharp and fast imaging of the EUI telescope, researchers could observe magnetic reconnection taking place repeatedly on very small scales.

In the early hours of April 20 a solar eclipse took place. Regions on Earth that saw, at least, a partial eclipse include parts of South/East Asia, Australia, and Antarctica. This meant that only a very small fraction of the world's population was able to witness this event. Even if it was a difficult eclipse to observe from the ground, PROBA2 had a front-row seat!

High-frequency sideways waves were detected for the first time using Europe's new solar observatory Solar Orbiter. These sideways waves are much more energetic than previously observed waves, and could play a role in heating the solar corona.

The telescope EUI onboard the satellite Solar Orbiter could capture Mercury while it transited the Sun. Scientists use the little black as a guide for science-approved photo-editing.

The PROBA2 PI-team welcomes research proposals for the tenth round of its Guest Investigator program for research based on SWAP and LYRA data analysis by scientists outside the SWAP and LYRA PI-teams.
