MM#009 Default Target



Dear Collaborators,

Solar activity remains low since the last message. The largest event 
during the period was a C3.9 flare at 09:08 UT today from NOAA 
14475 (S09W13, beta-gamma/D-type), which also produced a C3.1 
flare later in the period. The target region NOAA 14478 (S06E39, 
beta-gamma-delta/F-type) produced several low C-class flares and 
remains the largest and most magnetically complex region on the 
visible disk. Continued significant flux emergence is still visible in 
NOAA 14478, especially in its central part. Today, we will continue 
with NOAA 14478 as the target region. Further C-class activity is 
expected, with a chance of an isolated low M-class flare in the next 
24 hours.

The position of NOAA 14478 on 27-Jun-2026 11:30 UT is:

S06E39 (-592", -130")
