Dear Collaborators,

Solar activity continues to be at a high level. There were two major flares, an M6.9 at 09/12/14:31 UT and an M5.3 at 09/13/06:38 UT, produced by the west limb region NOAA 13811 (S13W91, beta-gamma/ D-type). This region was also the source of two low M-class flares and five C-class flares in the period. Considering that 13811 is almost rotating over the west limb, we still keep the Major Flare campaign on the southeast unnumbered region. It produced two low M-class flares, an M1.6 and an M2.1 after yesterday's X1.3 flare. This region has rotated onto the visible disk and seems to have a complex magnetic configuration. Low M-class flares are expected from the two regions as mentioned, with a chance of a >M5 flare in the next 24 hours.

The approximate position of the target on September 13 at 07:30 UT is:

S17E80 (-890", -280")
