Dear RHESSI Collaborators,

Solar activity has been at high levels for the past 24 hours.
The target region NOAA 12673 produced 9 M-class flares
(the largest one being a major M5.5 at 20:28 UT on September 4)
since the last message. Two of them were associated with halo
or Earth-directed CMEs. 12673 has a complex beta-gamma-delta
configuration, increasing in sunspot area (now 680 uh) and number
of spots significantly. It developed rapidly and continues to grow. At
this time we are implementing a Major Flare Watch campaign. Another
major (>M5) event is likely within the next 24 hours.

The position of NOAA 12673 on September 5 at 07:30 UT is:

S08W20 (323", -243")
