MM#003 Major Flare Watch
Dear RHESSI Collaborators,
NOAA 1515 has completed west limb passage. It was
the source of a few minor events yesterday. The new
target is NOAA 1520. 1520 is a very large region with
a complex F-type/beta-gamma-delta sunspot group.
Its H-alpha plage is displaying bright flare points and
dark surges. Previously somewhat quiescent, 1520
produced 3 M-class events in the past 24 hour period.
The largest was an M2.0 at 07/10/06:27. Additional
low-level M-class events expected with a major =/>M5
event possible in the next 24 hour period.
The position of NOAA 1520 on July 10 at 15:00 UT is:
