Subject: MM#003 Major Flare Watch" -
Date: Thu, 4 Dec 2014 14:30:02 -0800
Dear RHESSI Collaborators,
Solar activity is at a moderate level. The target region, NOAA 12222 is the source of an ongoing major event; a M6.1 flare on 4-Dec-2014 at 18:05. The region was also the source of C- and M-class events, since the previous message. The elongated mixed polarity structure mentioned yesterday has fragmented, and some of the rapidly moving component spots have combined with the large positive leading spot, forming a large mixed polarity structure (with the smaller negative spots joined at the trailing edge). Given the significant activity released so far and the ongoing rapid evolution, a Major Flare Watch is now in effect. Further M-class events are likely, with a significant chance for a >M5 flare.
The position of NOAA 12222 on 4-Dec-2014 at 20:35 UT is:
S20W34 ( 513", -339" )
See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
