Dear Collaborators,
Solar activity has slightly increased since the last message. NOAA 14048 (S15E59) remained the most flare-productive region in the period, producing over ten C-class flares and five low M-class flares, including the largest—an M1.6 at 16:27 yesterday. This region has developed into a beta-gamma configuration with increases in both spot area and number. 14048 is undergoing significant magnetic flux emergence in its intermediate portion. Today, the Major Flare Watch shall switch to this region. Yesterday's target NOAA 14046 (N05E39) has also increased in magnetic complexity to a beta-gamma configuration and produced a C7.6 flare in the period. Further low M-class activity is expected from the target region and also from NOAA 14046, with a chance of an above M5 flare in the next few days.
The position of NOAA 14048 on 31-March-2025 at 07:30 UT is:
S15E59 (-796",-192")
