MM#003 Major Flare Watch



Dear Collaborators,

Solar activity has dropped to an intermediate level since the 
last message. The largest event was a C8.2 flare at 16:58 UT 
yesterday from NOAA 13959 (N18W25, beta/C-type). The target 
region NOAA 13964 only produced four low-C flares in the period, 
including the largest being a C4.9 flare at 14:05 UT yesterday.  
This region has lost the delta configuration to be classified as 
a beta-gamma/E-type sunspot group. Today the Major Flare 
Watch will be extended for maybe the final 24 hours with 13964. 
Note that NOAA 13961 (S09E01, beta-gamma-delta/E-type) with 
a sunspot area of 780 μh, and NOAA 13968 (S19W78, beta/B-type) 
also were the two sources of ~C5 flare. Further C-class activity is 
expected, with a slight chance for an isolated >M5 flare in the 
following 24 hours.

The position of NOAA 13964 on 20-Jan-2025 at 12:30 UT is:

N06W69 (906", 132")
