MM#003 Major Flare Watch

Dear RHESSI Collaborators,

A large leader sunspot is visible on the NE limb. This new region was the likely source of the M3.5 event yesterday at 07:31 UT. This region is located northeast of newly numbered NOAA 1163. If possible, include 1163 within your F-O-V. An event equal to M5 or larger is possible in the next few days.

The approximate position of the target on February 25 at 11:00 UT is: N20E85 (Solar X = -908", Solar Y = 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.

Regards,

Bill Marquette (Helio Research)
