Dear Collaborators,

Solar activity has been still at an intermediate level since the last message. Yesterday’s target region NOAA 13559 produced 6 C-class flares, including the largest magnitude flare (a C5.7 flare at 17:34 UT on 30-Jan-2024), but it has almost rotated beyond the west limb. A newly numbered region NOAA 13567 has been classified as a beta/D-type configuration. It was a source of several low-C flares and has shown signs of additional flux emergence in the period. Today we shall end the Major Flare Watch campaign, and the default target shall switch to NOAA 13567. Further C-class activities are expected in the following 24 hours.

The position of NOAA 13567 on 31-Jan-2024 at 08:30 UT is:

N20E65 (-830", 371")
