SIDC Info
FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) 2024 May 27 18:24:08 A halo Coronal Mass Ejection (CME) was detected in SOHO/LASCO-C2 data from 07:24 UTC May 27. This CME has a plane of sky speed of around 800km/s and was predominantly directed to the east. It is associated with the X2.8 flare originating from beyond the east limb, with peak time 07:08 UTC on May 27. Due to the location of the source region, initial modelling suggests that the CME is not expected to impact Earth.

Return of the King!
Returning old active region NOAA 3664 produced an X2.8 flare on 27 May. Updates on further activity from this region will be posted here.
When the dust has settled...
Flare productivity from NOAA 13664 and the extreme geomagnetic storm on 10-11 May rank amongst the most impressive in the space weather domain. A perspective.
The King is dead, long live the King?
While NOAA 3664 has rounded the Sun's west limb, a new X-class flare producing active region has shown up near the Sun's east limb.Meet us at
