MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region (NOAA 2671, N11E13) is maintaining its large F-type/beta-gamma sunspot group but is somewhat stable producing only two minor C-class events since the last message. The largest was a C2.9 at 08/18/21:04 UT. The most productive region in the past 24 hours was an active region located about one half of a day beyond the northeastern limb. This new region was the source of multiple limb occulted C-class events. The largest was a C4.4 at 08/18/20:02 UT. The region is dynamic displaying bright H-alpha surges and spray-type prominences. The target will switch to the east limb region today. B- and C-class activity is still possible from 2671, but the limb region is currently more active. B-and C-class events probable with a chance for an isolated M-class in the next 24 hour period.
The approximate position of the target on Aug 19 at 15:30 UT is: N06E90 (Solar X = -943", Solar Y = 098")
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.
