MM#009 Default Target



Dear Collaborators,

Solar activity continues to decrease to a low level. The largest 
event since the last message was a C1.4 flare at 10:57 UT 
today from NOAA 14117. This region retained a beta/D-type 
magnetic configuration, with an increase in its sunspot area. 
To the southeast of 14117, NOAA 14118 (S14E29) also displayed 
visible magnetic flux emergence to become a beta/C-type 
group. Yesterday’s target NOAA 14114 only produced a C1.3 
flare. Today, we shall end the Major Flare Watch campaign, 
and the default target shall switch to NOAA 14117 (with NOAA 
14118 in the field of view). More C-class activity is expected 
in the following 24 hours.

The position of NOAA 14117 on 22-June-2025 at 11:30 UT is

S15E16 (-252", -274")
