Press release by the STCE on the strong solar storm of October 9.

view
 

On October 3, the Sun unleashed its most powerful eruption since 2017: a solar flare classified as X9.0 on the GOES scale, accompanied by a significant coronal mass ejection. We also observed a signal related to this flare in the Herzberg channel which is extremely rare.

NOAA 3848 produced a long duration X1 flare early on 9 October which was associated with an earth-directed coronal mass ejection (CME). ***UPDATED***

After all the excitement surrounding the Great American Eclipse earlier this year, it is easy to forget that another one of these mesmerising was scheduled for the fall. The PROBA2 team prepared for special observations on October 2 when the instruments onboard had a first row seat of the eclipse.

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.
