On 1 and 2 October, the Sun produced an M5, an M8 and an X1 flare. The source was not the large and complex active region NOAA 3112, but the much smaller and somewhat simpler NOAA 3110.


In white light, NOAA 13105 and 13107 looked like rather big and complex sunspot groups when they rounded the solar limb, but flare-wise they were quite a disappointment.


The Royal Observatory of Belgium hires a full-time scientific collaborator, who will play a central role in ROB’s research on campfires.


On 23 July 2022, 10 years after the Carrington-like event that happened on the same day, the Sun produced another quite strong event - again on its farside. Imagery by the Solar Orbiter has now revealed that the source was an erupting filament.


Two weeks after its flaring departure over the solar west limb, active region NOAA 3088 has returned near the southeast limb.


Fundamental Research

The STCE does Fundamental Research.

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.
