Solar activity has remained at a high level since the last message.
The largest event during the period was
an X1.0 flare at 11:19 UT
on 3-Jun from the target region NOAA 14455 (N14W25). This region
has increased in magnetic complexity to a beta-gamma-delta
configuration, and produced an M7.7 flare and numerous C-class
flares during the period. Today, we will continue the Major Flare
Watch campaign for NOAA 14455 for another 24 hours. Further
C-class flares are expected, with a chance of an isolated >M5 flare
in the next 24 hours.
