Dear Collaborators,
Solar activity has returned to a moderate level, due to an M3.4 flare at 10:08 UT produced by NOAA 13967. This region has undergone the emergence of additional negative magnetic fluxes in its intermediated portion over the past 24 hours, with a beta/C-type configuration. To the west of 13967, NOAA 13961 (S09W15, beta-gamma-delta/F-type) has also grown in the spot counts and area (to 800 μh) but only produced four C-class flares. Today we shall end the Major Flare Watch campaign, and the default target shall switch to NOAA 13967 because of its return to M-class flaring and proximity to 13961. Besides, NOAAs 13964 (Yesterday’s target) and 13968 near the west limb were the only sources of C-class flare. Further C-class activity is expected, with a good chance of another low-M flare in the following 24 hours.
The position of NOAA 13967 on 21-Jan-2025 at 12:30 UT is:
S17E19 (-304", -205")
