Dear Collaborators,

Solar activity has increased to a high level since the last message. 
The largest event during the period was an M9.3 flare at 01:22 UT 
today, 3-Jun, from the target region NOAA 14455 (N13W07, beta/
C-type; see the SSW Latest Events entry). This region was also 
the source of another M3.3 flare and several C-class flares during 
the period. At this time, we are implementing a Major Flare Watch 
campaign for NOAA 14455 due to its ongoing flux emergence 
around the leading main sunspot. Further C-class activity is 
expected, with a chance of an additional isolated >M5 flare in 
the coming days.

The position of NOAA 14455 on 3-Jun-2026 at 03:30 UT is:

N13W07, (112",220")
