MM#003 Major Flare Watch



Dear Collaborators,

Solar activity has risen to a moderate-to-high level since the last 
message. Target region NOAA 14246 (N22W50, beta-gamma-delta
/E-type) remains the most flare-productive area on the visible disk, 
producing a dozen C-class and three low-to-mid M-class flares in the 
period, including the largest event, an M4.8 at 03:49 UT today. At this 
time we are implementing the Major Flare Watch on NOAA 14246. 
Note that NOAA 14248 (N07W20, beta-gamma-delta/E-type) also 
produced an M2.0 flare during the period. Additional low M-class 
activity is expected, with a chance of a major flare above M5 in the 
next 24 hours.

The position of NOAA 14246 on 15-October-2025 at 11:30 UT is:

N22W50, (685",300")
