Dear Collaborators,

Solar activity continues at high levels for the past 24 hours.
The largest event since the last message was an M5.7 at
05/20/14:54 UT produced by the target region NOAA 13311.
13311 also produced another three M-class flares including
an M5.2 at 05/20/22:52 UT. It has been designated as a
beta-gamma-delta/E-type configuration with increasing
the sunspot area and number of spots. Please note that
NOAA 13305 (N12W78, beta/D-type) was the source of
ten C-class flares in the period. Additional low M-class flares
are expected with a chance of another >M5 flare in the next
few days.
