Dear Collaborators,

Solar activity has increased to a high level since the last message. NOAA 13873 located at the Eastern most of the active region group (made of NOAAs 13869, 13872 and 13873) produced an X1.9 flare at 06:32 UT today(10/26) following an M9.5 event at 05:58 UT associated with a filament eruption from the South side of this region.

NOAA 13863 is the smallest (120 millionths) and classified as a beta type, but has repeated eruptions observed in EUV wavelengths during the past 24 hours. We will continue the Major Flare Watch campaign with the target shifted to the South side of NOAA 13873. Additional M class flares or larger are expected in the next 24-48 hours.

The position of the target in NOAA 13873 on 26-October-2024 at 15:30 UT is: S12E54 (-771",-253").
