Dear Collaborators,

Solar activity continues at a high level. The largest event in the past 24 hours was an X3.5 flare at 08:18 UT on May 15 produced by yesterday's limb target NOAA 13664. 13664 also produced an M3.6 and a C9.9 flares when it was beyond the west limb. Today we will continue the Major Flare Watch campaign but the target switches to a southeast limb region (unnumbered yet) that has produced an X3.0 flare at 14:20 UT on May 15 plus two M3 flares. M-class activities are expected with a chance of some X-class flare in the next 24-48 hours.

The approximate position of the target on May 15 at 23:30 UT is:

S12E86 (-900", -200")
