Dear Collaborators,

Solar activity is at a high level. The target limb region has rotated on disk and has been designated as NOAA 13341, a beta/C-type sunspot group at the start of the UT day. Although NOAA 13342 (that is rotating up to the South West limb) has also produced M-class events, the target remains on NOAA 13341 and we are initiating a MM#003 Major Flare Watch. This is because 13341 has just produced an X1.1 flare on 20-Jun-2023 at 16:42 UT. Further M-class flares are expected in the next 24 hours, with a chance for another >M5 or X-class flare.

The position of NOAA 13341 on 20-Jun-2023 at 18:00 UT is:

S13E52 , ( -727", -229" )
