MM#009 Default Target



Dear Collaborators,

Solar activity has increased to a moderate level since the last message. 
Yesterday's target region, NOAA 14493 (N05W80), produced only a C1.6 
flare during the period and is approaching the western limb. The largest 
event during the period was an M3.2 flare at 15:17 UT yesterday from 
NOAA 14494 (S04W09), followed by an M1.0 flare at 02:32 UT today. 
Both M-class flares occurred on the western side of the leading sunspot 
in NOAA 14494. Today, the target will switch to NOAA 14494, although 
this region has lost its delta configuration and is showing some decay. 
NOAA 14495 (S02W20, beta/D-type), located near NOAA 14494, also 
produced several C-class flares during the period, including a C4.2 flare. 
If possible, please also include this region in your field of view. Further 
C-class activity is expected, with a chance of additional low-level M-class 
activity in the next 24 hours.

The position of NOAA 14494 on 27 July 2026 at 11:30 UT is:

S04W09 (148", -153")
