Dear Collaborators,

Solar activity has slightly increased since the last message. The target region has now been designated as NOAA 13813 (S22E51, beta-gamma/D-type). This region produced three low-M-class flares and one high-C-class flare during the period, while the largest magnitude flare in the period was an M2.9 on 2-Sep-2024 at 13:33 UT from NOAA 13807 (S16W52, beta- gamma/E-type). 13807 also produced another two low-M-class flares and over ten mid-C-class flares in the period. However, the Major Flare Watch will continue with NOAA 13813 as the target region for a further 24 hours, due to its prior flaring history. Further M-class activity is likely, with a chance of an isolated ≥M5 flare in the next 24-48 hours.

The position of NOAA 13813 on 3-Sep-2024 at 11:30 UT is:

S22E51 (-686",-424")
