Dear RHESSI Collaborators,

The target region NOAA 11726 was the source of an M1.0 flare at 10:22 UT yesterday. Since then the region has grown to over 500 uh and is now harboring a large delta spot in its trailing portion. It has also begun to show signs of shearing and H-alpha brightening at the location of the delta. At this time we are implementing a Major Flare Watch due to the increased possibility of an M5 flare or greater over the next 24-48 hours.

The position of NOAA 11726 on 23-Apr-2013 at 09:00 UT is:

N13W40, ( 602", 275" )

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.
