MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 2672 has an E-type/ beta-gamma sunspot group with a possible small magnetic delta configuration located within its trailing portion. 2672 was the source of B- and C-class events since the last message. The largest event was a C9.4 at 08/20/19:39 UT. 2672 also produced a C5.9 at 08/21/03:16 UT. NOAA 2671 (F-type/beta-gamma) was the source of two minor B-class events in the past 24 hours. B- and C-class events expected with the chance of an isolated M-class from the target region 2672 and/or 2671 in the next 24 hour period The position of NOAA 2672 on August 21 at 14:00 UT is: N07E68 (Solar X = -875", Solar Y = 072") 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 northeastern limb target region, now numbered NOAA 2672, produced an isolated M1.1 event at 08/20/01:52 UT. It also produced a few B- and C-class events in the past 24 hours. Former target 2671 (F-type/beta-gamma) was the source of a C7.0 event at 08/19/21:55 UT. 2672 is too close to the limb to ascertain its magnetic configuration but it has an unusual tilted magnetic inversion line and continues to display bright surges. Both 2671 and 2672 have the potential to produce B- and C-class events with the chance of an M-class event in the next 24 hour period. The position of NOAA 2672 on August 20 at 17:00 UT is: N07E80 (Solar X = -928", Solar Y = 095") 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 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 2671 (F-type/beta-gamma) has decayed losing its weak magnetic delta configuration. 2671 was the source of several B-class events since the last message. The largest was a B9.5 at 08/18/08:52 UT. B-class activity expected with the chance of a C-class event in the next 24 hours.There is also a very slight chance of an isolated M-class event. The position of NOAA 2671 on August 18 at 13:00 UT is: N11E28 (Solar X = -439", Solar Y = 083") 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 2671 is still slowly developing adding spot count and area and magnetic complexity. 2671 was the source of numerous B-class events since the last message. 2671 extended its sunspot group to an F-type group with a beta-gamma-delta magnetic classification. The weak delta configuration, located within the intermediate portion of the region, is currently displaying an absence of bright H-alpha emission over the umbrae. B-class activity expected, C-class events probable with a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2671 on August 17 at 14:45 UT is: N11E42 (Solar X = -625", Solar Y = 099") 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 2671 continues in growth phase adding sunspot area and sunspot count especially within its intermediate and trailing portions. 2671 is currently a large E-type/beta region with some minor mixed polarities. 2671 was the source of numerous B-type events in the past 24 hours. B- and C-class events probable with the slight chance of an isolated M-class event if growth continues to result in increased magnetic complexity. The position of NOAA 2671 on August 16 at 14:45 UT is: N12E55 (Solar X = -761", Solar Y = 134") 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 (now numbered NOAA 2671) produced numerous minor B- and C-class events since the last message. The largest was a C2.3 at 08/14/22:10 UT. 2671 is currently displaying dynamic bright H-alpha plage along with a dark active filament and a beta magnetic configuration with some minor mixed polarities. Additional B- and C-class activity probable in the next 24 hour period. The position of NOAA 2671 on August 15 at 14:45 UT is: N11E68 (Solar X = -864", Solar Y = 139") 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 2670 has completed west limb passage. The target will switch to a new region rotating over the northeastern limb that was the source of several minor events since the last message. The largest was a C2.7 at 08/14/10:46 UT. This region is displaying dynamic bright H-alpha plage. The region's sunspot group is too close to the limb to ascertain it's magnetic configuration. B-class events expected with the chance of another C-class event in the next 24 hour period. The approximate position of the target on Aug 14 at 15:00 UT is: N10E85 (Solar X = -930", Solar Y = 154") 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 continues at very low levels. NOAA 12670 is now on the western limb and has remained quiescent. It shall continue to be the target region for a further 24 hours although no activity is expected before west limb passage. The position of NOAA 12670 on 13-Aug-2017 at 13:30 UT is: S07W80, ( 925", -133" ) 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, Quiet-Sun conditions continue. Alpha region NOAA 12670 has remained quiescent as it approaches the western limb. It shall remain the target region for a further 24 hours although no increase in activity is expected. The position of NOAA 12670 on 12-Aug-2017 at 15:30 UT is: S07W68, ( 872", -154" ) 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.
