Dear Collaborators,
Solar activity has maintained a moderate level since the last message. The target region NOAA 13873 reduced both in size and magnetic complexity. Only flare event reported from the active region group (consisting of NOAA 13869, 13872 and 13873) in the past 24 hours was a C3.8 at 6:11 UT today (10/28) from NOAA 13869. At this time, we will end the Major Flare Watch campaign with this active region group.
The major source of flare activity was from the Northeast limb region, now designated as NOAA 13878, which produced 3 M class flares on 10/26. This region produced another 2 M class flares (M2.9 at 23:05 UT on 10/27 and M1.3 at 3:59 UT on 10/28) as well as several mid-to-high C class flares during the past 24 hours from its following (negative polarity) sunspot. We will observe the following sunspot of NOAA 13878 as a default target for the next 24 hours. Additional C to M class events are expected, with a slight chance of a major (>M5) flare.
The position of the target in NOAA 13878 on 28-October-2024 at 15:30 UT is: N14E70 (-878",218").
