MM#009 Default HESSI Target

01 Sep '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, NOAA 1281, added a few more spots and increased magnetic complexity slightly. Its sunspot group is currently classified D-type/beta-gamma. The largest event in the past 24 hour period was a C2.0 at 09/01/12:45 UT produced by NOAA 1283 (N12E52). Both 1281 and 1283 should produce additional C-class events with even a very slight chance of an isolated M-class event in the next few days. The position of NOAA 1281 on September 01 at 15:30 UT is: S20E19 (Solar X = -291", Solar Y = -429") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target region, now numbered NOAA 1283 (N12E62), was the source of a C2.2 event at 08/31/13:22 UT. The largest event in the past 24 hours was produced by NOAA 1281. New flux rapidly emerged in the trailing portion of the region overnight. 1281 currently has a D-type/beta sunspot group. The target will switch from 1283 to 1281 for at least the next 24 hour period. Another C-class event is possible. The position of NOAA 1281 on August 31 at 15:30 UT is: S20E31 (Solar X = -461", Solar Y = -419") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target region has partially rotated over the northeast limb. It is too close to the limb to fully ascertain its magnetic classification but it appears to have a simple beta configuration. B-class events are probable with a C-class event possible within the next 24 hour period. The position of the target region on August 30 at 15:00 UT is: N14E85 (Solar X = -919", Solar Y = 218") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, All regions on the visible solar disk are currently decaying or stable and are quiescent. There is an active region located beyond the northeast limb that has been the source of C-class activity today.The largest was a C3.7 at 08/29/07:21 UT. Additional C-class events expected during the next 24 hour period. The approximate position of the target on August 29 at 08:00 UT is: N14E90 (Solar X = -922", Solar Y = 228") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1271 was the source of a B5.4 limb flare at 08/28/04:22 UT. The flare was associated with a beautiful CME off the west limb. 1271 has completed west limb passage. The target region will switch to the region located near the southeast limb which has produced B-class events in the past 48 hours. The region is displaying minor surging and a few bright points in H-alpha images. It currently has a simple magnetic configuration. No significant flare activity is expected in the next 24 hour period. The position of the target region on August 28 at 14:15 UT is: S20E73 (Solar X = -855", Solar Y = -355") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1271 was the source of B-class activity during the past 24 hour period. A new region located just beyond the east limb at approximately S18 also produced a B6.3 event at 05:35 UT today. Target region, 1271 should produce additional minor events before it completes west limb passage. The target will most likely switch to the the east limb region tomorrow. The position of NOAA 1271 on August 27 at 15:30 UT is: N17W78 (Solar X = 888", Solar Y = 252") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1271 produced numerous B-class events and two C-class events in the past 24 hour period. The largest C-class event was a C2.3 at 08/26/13:13 UT. 1271 has decayed significantly but could still produce B-class events with a chance of another C-class event before west limb passage. The position of NOAA 1271 on August 26 at 10:30 UT is: N17W62 (Solar X = 802", Solar Y = 223") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1271 has decayed somewhat in overall sunspot area and count but still remains a large E-type sunspot group and reclaimed a beta-gamma magnetic classification. B-class events are probable with a slight chance of an isolated C-class event. There is only a very slight, <10%, chance of an M-class event in the next few days. The position of NOAA 1271 on August 25 at 15:30 UT is: N17W51 (Solar X = 707", Solar Y = 205") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare event activity continues at a low B-class level. Target region, NOAA 1271, is mostly unchanged currently displaying a large E-type/beta sunspot group. There is a new region located mostly beyond the east limb at approximately N16 that was also the source of a B-class event today. B-class events are expected with a chance of a C-class event in the next 24 hour period. There is <10% chance of an isolated M-class event in the next few days. The position of NOAA 1271 on August 24 at 15:30 UT is: N17W38 (Solar X = 560", Solar Y = 188") 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.

Dear RHESSI Collaborators, Solar activity remains low with one C class flare in the past 24 hours, produced by NOAA 11271. Given that all regions on disk appear to be decaying and 11271 remains the only region with multiple, large penumbral sunspots and a beta-gamma classification, it shall continue to be todays target. C class activity may be possible. The position of NOAA 11271 on 23-Aug-2011 15:30 UT is: N17W25 ( 384", 176" ) 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.
