The STCE's SC25 Tracking page has been updated to reflect the latest evolution in some critical space weather parameters for the ongoing solar cycle 25 (SC25).


On 20 January, a large filament in the southwest solar quadrant erupted producing some spectacular images.


Solar activity continued to be elevated, with both the sunspot number and the solar radio flux reaching their highest values so far this solar cycle.


The Sun produced a 3rd X-class flare in just 5 days. This page features the ongoing series of X-class flares and other solar activity. UPDATED 1.


A side-by-side comparison of and more details on the X-class flares from 6 and 9 January.

Public Outreach

Open DoorsThe STCE does public outreach during the STCE Annual Meeting and the Open Doors of the Space Pole in Uccle.

One of the highlights of the Open Doors is always a visit to the Solar Dome. A small introductory presentation is first given in the corridor of the SIDC. Skilled observers and space weather forecasters explain in laymen terminology what sunspots are, how they are observed, why these observations are so important, and how solar eruptions affect us and our technology. Then, the small groups of 10-15 people are guided stairs towards the top of the solar dome. There, the various solar telescopes are shown and their specific applications are discussed. Weather permitting, the visitors can also make solar observations using a projected solar image from the white light solar telescope. During and after the visit, there is plenty of opportunity to ask questions to the guides.
