Dear RHESSI Collaborators,

The Major Flare Watch region NOAA 12673 produced an X9.3
flare at 11:53 UT on September 6, which was associated with an
Earth-directed CME. This X-ray event is the largest one in this
solar cycle (as of now; also the largest one since 2005). 12673
also produced three low M-class events. It has been classified
as a complex E-type/beta-gamma-delta configuration with still
increasing sunspot area (960 uh now). We will continue the Major
Flare Watch as the region still has the potential to produce additional
>M5 flares in the next few days.

The position of NOAA 12673 on September 7 at 07:30 UT is:

S09W49 (711", -226")
