MM#003 Major Flare Watch

MM#003 Major Flare Watch

Dear RHESSI Collaborators,

Target region, NOAA 1166, was the source of a major X1.5 flare late yesterday at 23:23 UT. 1166 developed rapidly during the day increasing its spot count, spot area and magnetic complexity forming a strong delta configuration within its central portion. If the region retains its magnetic complexity, an event => than M5 is possible.

The position of NOAA 1166 on March 10 at 11:30 UT is: N09W19 (Solar X = 311", Solar Y = 264")

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,
