Dear Collaborators,

Solar activity has been at a low-to-moderate level in the last 24 hours. The largest event since the last message was an M2.5 flare at 13:49 UT today from NOAA 13764 (alpha/H-type, S11E88). NOAA 13762 has increased its magnetic complexity to be classified as a beta-gamma-delta/E-type configuration and produced a C9.0 flare at 15:20 UT yesterday. Yesterday’s target NOAA 13751 (beta-gamma-delta/E-type, S08W49) showed magnetic signs of decay and only produced a C4.5 flare. Today we shall end the Major Flare Watch campaign, and the default target shall switch to NOAA 13762 due to its increased configuration and prior flaring history. Further C-class flares are expected with a chance for additional low-M flares in the next 24 hours.

The position of NOAA 13762 at 14:30 UT on 23-Jul-2024 is:

S13E29 (-450", -283")
