MM#003 Major Flare Watch



Dear Collaborators,

Solar activity has increased to a high level since the last message. 
The largest event in the period was an M7.5 flare at 01:07 UT today 
from the target region NOAA 14409 (N02W08; see the SSW Latest 
Events entry). This region has remained the dominant source of 
activity on the visible disk, producing numerous C-class flares and 
two additional low-M flares (M1.7 and M1.2) during the period. 14409 
retains a beta-gamma configuration, and its leading sunspots are 
showing signs of shearing and ongoing flux emergence. At this time, 
we are implementing a Major Flare Watch with NOAA 14409. Further 
C-class activity is expected, with a chance of an isolated  >M5 flare 
over the next 24–48 hours.

The position of NOAA 14409 on 4-Apr-2026 at 11:30 UT is:

N02W08 (133",139")
