NOAA 3947 has been the source of several X- and M-class flares over the last 48 hours. ***Updated (2)***
Coronal mass ejections, associated with a series of M- and X-class flares on 29 and 30 December, have resulted in a severe geomagnetic storm. ***UPDATED (4)***
“Signal received” After a smooth launch that was postponed by one day, operators and scientists waited to receive a first sign of life from the Proba-3 satellites.
Proba-3 is the latest ESA mission to be launched on December 4, 2024. The exploitation of ASPIICS, the instrument imaging the solar corona, is in the hands of the Royal Observatory of Belgium (ROB), where the associated scientific research will also be coordinated.
Last week was marked by a surprise proton event, with its source on the Sun's farside.
An interesting filament eruption took place in the Sun's southern hemisphere on 11 November.

Good news from the Proba-3 front!
After a small delay due to problems with transport, the two satellites finally made it to India. They landed safely on November 5 to be transported to the launch site in Chennai. There, the final preparations for launch are ongoing. Currently the launch of Proba-3 is planned for December 4.
Another X-class flare, another source region. NOAA 3883 produced a X2.3 flare on 6 November.
