MM#009 Default Target



Dear Collaborators,

Solar activity has increased since the last message. The largest event 
during the period was a C7.5 flare at 21:06 UT yesterday from NOAA 
14475 (S10W26, beta-gamma/D-type). NOAA 14475 became the most 
flare-productive region during the period, producing five additional low 
C-class flares. The target region NOAA 14478 (S06E26, beta-gamma-
delta/F-type) produced only a C2.1 flare but remains the largest and 
most magnetically complex region on the visible disk. Today, the target 
region will remain NOAA 14478, as it is showing ongoing significant flux 
emergence. Further C-class activity is expected, with a slight chance 
of an isolated low M-class flare in the next 24 hours.

The position of NOAA 14478 on 28-Jun-2026 11:30 UT is:

S06E26 (-412", -136")
