Dear Collaborators,

Solar activity continues at a moderate level. The largest event
since the last message was an M2.9 at 07/15/07:21 UT from
NOAA 13363. 13363 was also the source of more than ten C-
class flares in the period. It retains a beta-delta/D-type configuration.
Today the Major Flare Watch region will switch to 13363. The
previous target NOAA 13372 produced two low M-class flares,
an M1.1 at 09:43 UT and an M2.2 at 10:05 UT on July 15, and
also five C-class flares. 13372 retains its beta-delta/E-type
configuration. Some other regions (NOAA 13368, 13370, and
13373) produced a few C-class flares as well. Additional low
M-class flares are expected with still a chance of an above M5
flare in the next few days.

The position of NOAA 13363 on July 16 at 03:30 UT
