</address> <pre> </pre> Dear RHESSI Collaborators,
<br />The Major Flare Watch region NOAA 12673 was the source of
an X2 flare, which is happening right now (peaking at ~9:10 UT).
12673 also produced a few C-class flares as well as an M2.3
yesterday. It retains its beta-gamma-delta/D-type classification,
but still increases in sunspot area and number of sunspots. Its
magnetic inversion line is highly sheared. Additional major flares
are possible in the next few days.
<br />The position of NOAA 12673 on September 6 at 07:30 UT is:
<br />S09W34 (527&quot;, -246&quot;)
