Dear Collaborators,
Solar activity has continued at a high level. The largest events since the last message were an M8.5 flare at 17:45 UT yesterday and an M6.3 flare at 09:17 UT today from NOAA 14114. This region has been classified as a beta-gamma-delta/E-type sunspot group, with an emergence of new visible magnetic fluxes surrounding its main spots. Yesterday’s target NOAA 14105 showed no M-class activity as it is currently rotating out of Earth-view. Today the Major Flare Watch shall switch to 14114 from 14105, due to a higher probability of another >M5 flare from 14114 in the coming days.
The position of NOAA 14114 on 16-June-2025 at 11:30 UT is
N17E05 (-79", 258")
