Dear Collaborators,

Solar activity has increased further to a high level since the last 
message. The largest event during the period was an M6.6 flare 
at 09:53 UT today, produced by target region NOAA 14366 (N13E46). 
The region also produced four additional low M-class flares and 
more than ten C-class flares during the period. 14366 has evolved 
into a beta-gamma-delta magnetic configuration, with significant 
ongoing flux emergence. At this time, we are implementing the 
Major Flare Watch campaign for NOAA 14366. Additional major 
flares above M5.0 are likely over the next few days.

The position of NOAA 14366 on 1-Feb-2026 08:30 UT is:

N13E46 (-684",287")
