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

The solar telescopes of the Royal Observatory (USET) observed the partial -as seen from Belgium- solar eclipse of 12 August 2026.
What goes on inside the walls of the Space Pole institutes in Uccle?
On 26 and 27 September, we opened our doors tot the public, and almost 9000 visitors came by to find out and help us celebrate the 20th anniversary of the STCE and the 200th anniversary of the Royal Observatory of Belgium!
The Journal of Space Weather and Space Climate (JSWSC - https://www.swsc-journal.org/ ) has opened a Topical Issue (TI) "Space Climate: From Solar Variability to Terrestrial Impacts".
On 5 September, a spotless active region produced an M-class flare which was associated with a fast coronal mass ejection and a minor proton event. (***ADDENDUM***)
On 21 August, a moderate solar flare near the Sun's west limb was associated with impressive post-eruption coronal loops.
By now, you must have seen the amazing images of the total eclipse that occurred last week. However, did you know this total eclipse was also seen from space?
When a total eclipse occurs on Earth, solar imagers in space usually only observe a partial eclipse, due to a different alignment between the Sun, the Moon and the spacecraft. However, on August 12, the ASPIICS coronagraph onboard Proba-3 was in just the right place at the right time!
The "Game of the Goose... for Satellites!" is a special, educational version of the classic "Game of the Goose" illustrating the various space weather impacts on satellites.It integrates the effects of solar flares, solar energetic particles and geomagnetic disturbances.
On 8-9 June 2026, ICAO -the International Civil Aviation Organization- organised a 2nd Space Weather User Workshop on the provision and use of space weather information for international civil air navigation. Once again, the team at STCE contributed significantly to the workshop preparations and realization.
A solar filament erupted late on 7 July. The associated coronal mass ejection did not affect the earth environment.
Two large sunspot groups, NOAA 4478 and NOAA 4479, have been dominating the sunspot and flare activity during the previous week.
While NOAA 4479 is approaching the Sun's west limb merrily producing M-class flares, a new active region NOAA 4482 has rounded the Sun's southeast limb producing an X1.3 flare.
