MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target region now numbered NOAA 1563 was the source of C-class events in the past 24 hours. 1563 appears to have decayed after its east limb passage. NOAA regions 1554, N16W75, 1560, N03E12, and the unnumbered region at S15E76 also produced C-class events. The most interesting region is NOAA 1560 which has developed a somewhat magnetically complex D-type/beta-gamma sunspot group. C-class events probable with an isolated M-class event possible in the next 24 hour period. The position of NOAA 1560 on August 31 at 17:00 UT is: N03E12 (Solar X = -198", Solar Y = -067") 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, Target region NOAA 1555 was stable and quiet. The southern limb region mentioned yesterday was very active during the past 24 hours. It was the source of 7 C-class events and an M1.3 event at 08/30/2:11 UT. The region is too close to the limb to ascertain its magnetic configuration. We will switch to the SE limb region today. C-class events expected with another M-class event probable in the next 24 hour period. The approximate position of the target on August 30 at 12:00 UT is: S25E85 (Solar X = -858", Solar Y = -408") 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 activity is very low. The target region will continue to be NOAA 1555 for another 24 hours. 1555 is mostly unchanged. The target will most likely switch tomorrow to an active region located beyond the southeast limb that was the source of minor B-class events since the last message. No significant activity expected in the next 24 hours. The position of NOAA 1555 on August 29 at 13:00 UT is: N08E21 (Solar X = -338", Solar Y = 021) 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 activity is very low with only minor B-class events during the past 24 hours. The northeastern target region has rotated fully on the disk. It is a decaying plage with a simple B-type/beta sunspot group with two spots. The target will switch to NOAA 1555. 1555 has a D-type/beta sunspot group with about 20 spots. A minor C-class event is possible in the next 24 hour period. The position of NOAA 1555 on August 28 at 13:00 UT is: N08E35 (Solar X = -541", Solar Y = 035") 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 regions on the visible solar disk are stable. The target will switch to the northeastern limb area to a region rotating onto the disk. The region is too close to the limb to ascertain its magnetic configuration but it was the source of a few B-class events and a low level C-class event since the last message. Another C-class event is possible in the next 24 hour period. The approximate position of the target on August 27 at 9:30 UT is: N11E86 (Solar X = -931", Solar Y = 172") 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 is at a very low level. NOAA region 11554 has grown in spot area coverage since yesterday's initial NOAA designation and has maintained a beta/D-type sunspot group class. A new region has rotated over the NE limb and is designated as NOAA 11555. This region appears to have the largest spot area on disk, but today's target will remain as 11554 due to past flaring history. B-class activity is probable, with a chance for low C-class events. The position of NOAA 11554 on 26-Aug-2012 at 14:00 UT is: N16W08, ( 123", 149" ) 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, Yesterday's target region has been designated as NOAA region 11554. This region has continued to evolve, now showing substantial spots and mature penumbrae in a beta/D-type sunspot group classification. NOAA region 11554 produced a C1.7 flare on 25-Aug-2012 at 02:24 UT. More C-class activity is possible in the following 24 hours. The position of NOAA 11554 on 25-Aug-2012 at 09:00 UT is: N16E07, ( -113", 149" ) 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, The level of solar activity remains very low. A new region has emerged in the North East quadrant, developing several clear spots in the past 24 hours. This unnumbered region appears to have a beta magnetic class with well-developed coronal loops, and is currently forming penumbrae. B-class activity is possible in the following 24 hours, with a chance for some low C-class events if further magnetic flux emerges. The approximate position of this region on 24-Aug-2012 at 10:00 UT is: N16E22, ( -347", 157" ) 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 is at a very low level. NOAA region 11548 has continued to maintain spot area, number of spots, and a beta/C-type sunspot group class. Although NOAA 11548 has recently only produced B-class events, this region will remain the target due to its compact population of coronal loops that are bright across a range of temperatures. B-class activity is probable, with a chance for C-class events. The position NOAA 11548 on 23-Aug-2012 at 12:30 UT is: N18E11, ( -175", 184" ) 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, NOAA region 11548 has shown no significant evolution since yesterday's message with maintaining spot area, number of spots, and a beta/C-type sunspot group class. NOAA 11548 has produced only B-class events in the past 24 hours. Continued B-class activity is expected, with a chance of some C-class events in the following 24 hours. The position of NOAA 11548 on 22-Aug-2012 at 09:30 UT is: N18E27, ( -408", 194" ) 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.
