Don’t forget to come visit our radio antenna's in the coming weekend! It is a unique opportunity to have fun with the whole family in a beautiful environment.

ESA’s Solar Orbiter spacecraft has discovered a multitude of tiny jets of material escaping from the Sun’s outer atmosphere. Each jet lasts for between 20 and 100 seconds, and expels plasma at around 100 km/s. These jets could be the long-sought-after source of the ‘solar wind’.

A joint scientific team led by the Royal Observatory of Belgium (ROB) and the KU Leuven has found that high-frequency magnetic waves could play an essential role in keeping the Sun’s atmosphere at millions of degrees. This finding sheds a new light on the most intriguing solar mystery: what makes the Sun’s atmosphere hotter than its surface?

The SIDC Forecasters at the Royal Observatory of Belgium played a key role in an ESA exercise to define how to communicate clearly on the impacts of extreme space weather events.

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
