MM#009 Default Target



Dear Collaborators,

Solar activity has decreased to a low level since the last message. 
The largest event during the period was a C2.1 flare at 20:11 UT 
on 4-Jun from NOAA 14458 (S05W28). The target region NOAA 
14455 (N15W41) produced only one C1.5 flare during the period 
and has decreased in complexity to a beta-gamma magnetic 
configuration. NOAA 14457 (S09W79, beta/C-type) also produced 
four low C-class flares in the period. Today, we will end the Major 
Flare Watch campaign and continue to watch NOAA 14455 as the 
default target region due to its recent flare history. 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 14455 on 5-Jun-2026 at 11:30 UT is:

N15W41, (600",247")
