MM#009 Default HESSI Target
by Max Millennium Chief Observer 28 Feb '17

28 Feb '17

Dear RHESSI Collaborators, Solar activity is at a very low level. The newly spotted region in the North East quadrant is now numbered NOAA 12641. This region has been designated as a beta/C-type sunspot group classification and displays a double bipole magnetic structure. NOAA 12641 has been the source of six B-class events over the past 24 hours, including the largest flare within the period (a B9.3 on 27-Feb-2017 at 20:07 UT). Further B-class activity is expected over the following 24-hour period. The position of NOAA 12641 on 28-Feb-2017 at 20:00 UT is: N15E35, ( -538", 346" ) 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 2638 continues to decay and continues to be quiescent. There were no events in the past two days. 2638 is currently displaying only a single round sunspot. No significant solar flare activity expected in the next 24 hour period. The position of NOAA 2638 on February 26 at 07:30 UT is: N17W06 (Solar X = 097", Solar Y = 398") 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 2638 is mostly unchanged and is currently much less dynamic today. B-class activity is still possible with the chance of a C-class event less likely in the next 24 hour period. The position of NOAA 2638 on February 25 at 08:00 UT is: N17E07 (Solar X = -113", Solar Y = 398") 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 2638 produced two C-class events in the past 24 hours. The largest was a C1.3 at 02/23/20:53 UT. 2638 has significantly decayed since the last message. B-class events possible with a slight chance of another C-class event in the next 24 hour period. The position of NOAA 2638 on February 24 at 14:30 UT is: N18E15 (Solar X = -240", Solar Y = 410") 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 2638 continues to slowly decay especially within its northern portion. 2638 was the source of minor B-Class activity in the past 24 hours. Additional B-class events probable with the chance of an isolated C-class event in the next 24 hour period. The position of NOAA 2638 on February 23 at 14:30 UT is: N19E28 (Solar X = -432", Solar Y = 415") 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 2638 was the source of an isolated C4.1 event at 02/22/13:27 UT. 2638 has decayed, losing sunspot area within its northern portion but is maintaining weak mixed polarities. B-class events expected with the chance of another C-class event in the next 24 hours. The position of NOAA 2638 on February 22 at 13:45 UT is: N18E43 (Solar X = -631", Solar Y = 382") 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 2638 is mostly unchanged maintaining two separate leader polarity sunspots and its beta magnetic configuration. 2638 produced a few B-class events in the past 24 hours. B-class events expected with a C-class event possible in the next 24 hour period. The position of NOAA 2638 on February 21 at 11:45 UT is: N18E58 (Solar X = -784", Solar Y = 358") 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 east limb target region is now numbered NOAA 2638. 2638 includes two closely spaced regions with beta magnetic configurations that appear to have some interaction. 2638 was the source of a few B-class events since the last message. The largest was a B7.5 at 02/20/14:25 UT. B-class events expected with a C-class event possible in the next 24 hours. The position of NOAA 2638 on February 20 at 13:45 UT is: N18E78 (Solar X = -903", Solar Y = 321") 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 east limb target region has rotated onto the visible solar disk but is still too close to the limb to ascertain its magnetic complexity. The target was the source of two occulted B-class events since the last message. The largest was a B3.0 at 02/19/05:41 UT. There is a separate region with a large leader sunspot located just south (N15E90) of the target region. B-class events probable with the chance of a C-class event in the next 24 hours. The position of the target on February 19 at 17:00 UT is: N20E85 (Solar X = -909", Solar Y = 339") 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 2636 has decayed since the last message and was quiescent. The target will switch to a region located about one day beyond the northeastern limb. The region was the source of occulted minor B-class activity. Additional B-class activity is possible in the next 24 hour period. The approximate position of the target on Feb. 18 at 03:30 UT is: N16E87 (Solar X = -932", Solar Y = 271") 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.
