MM#003 Major Flare Watch
Dear RHESSI Collaborators,
A strong EFR located between NOAA 1160 and 1161 was the source of an M6.6 event at 02/18/10:11 UT. This region has a beta-gamma-delta magnetic configuration and continues in strong growth phase. NOAA 1158 continues to slowly decay. It produced numerous C-class events yesterday. We'll continue a Major Flare Watch but switch from 1158 to the new EFR in the NE. Another M5 or stronger event is possible from the new region. Another M-class event is also possible from 1158.
The position of the target EFR on February 18 at 8:30 UT is: N18E04 (Solar X = -064", Solar Y = 411")
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.
