Dear Collaborators,

Solar activity has slightly increased since the last message. The largest event during the period was a C6.3 flare at 05:19 UT today from NOAA 14492 near the west limb (N16W88; see the SSW Latest Events entry https://www.lmsal.com/solarsoft/latest_events/#AR_4492_on_North_West_Limb_N16W88_11_Hours_7_Flares_Last_Largest_C6.3). This region also produced several other C-class flares, including C4.0 and C2.5 events, but has rotated out of view from Earth. The target region NOAA 14498 (N14E03) produced no significant flares during the period, but has developed into a beta-delta magnetic configuration, with an increase in spot number. Nearby NOAA 14500 (N18E07, beta/ D-type) has also shown slight growth. Today we will continue to watch NOAA 14498 as the target region. If possible, please also include 14500 in your field of view. Further C-class activity is expected, with only a slight chance of an isolated low M-class flare in the next 24 hours.

The position of NOAA 14498 on 2-Aug-2026 at 11:30 UT is:

N14E03 (-48", 134")
