Another X-class flare, and once again from a different region. NOAA 3878 was the source of an X2.0 flare on 31 October.

The solar storms of 24 and 26 October are compared from the initial X-class flare to the geomagnetic disturbance that resulted from the associated coronal mass ejection.

Another X-class flare, but from a different region. The associated coronal mass ejection may deliver a glancing blow on 28 October.

The BRAMS team produced a short movie that explains the difference between meteoroids, meteors and meteorites, radio observations of meteors, BRAMS, and what you see in a spectrogram.

The Sun produced a strong X3.3 flare on 24 October. The associated coronal mass ejection, expected to deliver a glancing blow, actually arrived on 26 October at 15:35UTC (DSCOVR).  A minor geomagnetic storm is expected. ***UPDATED (2)***

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.
