Dear Collaborators,
There was just an M9.4 flare (at 07:24 UT) produced by a region beyond the northeast limb mostly. At this time, we are implementing the Major Flare Watch campaign on this limb region. This region also produced an M1.1 flare at 20:11 UT yesterday. Also note that yesterday's target NOAA 13906 (S16E42) has developed to a beta- gamma-delta/E-type region with a sunspot area of ~500 MSH and was the source of two M-class (M1.1 and M1.8) and five C-class flares since the last message. Further C- and low M-class activities are expected with a good chance of another major flare (>M5) in the next few days.
The approximate position of the target on November 25 at 08:30 UT is:
N20E89 (-940", 325")
