MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 2473 continues to decay especially within its trailing polarity portion which is currently nearly spotless. The largest event 2473 produced since the last message was a C4.3 at 12/30/22:45 UT. 2473 has an active filament located along its main magnetic inversion line and is displaying frequent bright and dark surging. Another C-class event is possible but an M-class event is less likely in the next 24 hour period. The position of NOAA 2473 on December 31 at 15:35 UT is: S21W56 (Solar X = 756", Solar Y = -324") 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 2473 has decayed significantly losing sunspot area and count and it has also simplified magnetically losing its delta configuration. The largest event 2473 produced in the past 24 hours was a minor C2.5 event at 12/29/20:19. Another C-class event is possible and there is still a slight chance of an isolated M-class event in the next 24 to 48 hour period. The position of NOAA 2473 on December 30 at 15:35 UT is: S21W42 (Solar X = 611", Solar Y = -317") 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 2473 was the source of C-class events in the past 24 hour period. The largest was a C6.8 at 12/29/10:32 UT. 2473 is maintaining its large F-type/beta-delta sunspot group. C-class events expected with the chance of an M-class event in the next 24 to 48 hours. The position of NOAA 2473 on December 29 at 15:35 UT is: S22W28 (Solar X = 426", Solar Y = -329") 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 2473 was the source of an isolated long-duration M1.9 event at 12/28/12:45 UT. The M-class x-ray event was associated with a large double-ribbon flare and eruptive filament. 2473 also produced a few C-class events since the last message. 2473 is maintaining its large F-type/beta-delta sunspot group. Another M-class event is possible in the next 48 hours with C-class events probable. The position of NOAA 2473 on December 28 at 15:35 UT is: S22W14 (Solar X = 219", Solar Y = -327") 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 a low level. Over the past 24 hours, NOAA 12473 has again grown significantly in number of spots and marginally in spot area. This growth has resulted in 12473 being redesignated as a beta-gamma-delta/F-type sunspot group, but it may have already lost the weak delta-spot in its intermediate portion. This region has only managed to produce B-class events since the last message but includes the largest magnitude flare of the period - a B9.7 on 27-Dec-2015 at 11:58 UT. Further C-class activity is expected over the following 24 hours, with a chance for an isolated low M-class flare. The position of NOAA 12473 on 27-Dec-2015 at 16:30 UT is: S22E00, ( -1", -328" ) 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 is low. NOAA 12473 continues to be the largest and most complex region on disk. NOAA 12473 grew in number of spots and marginally in spot area over the past 24 hours, while losing a significant amount of penumbrae from its internal spots. 12473 has retained a beta-gamma/E-type sunspot group designation and has continued to produce the majority of the ongoing C-class activity, including the largest magnitude flare since yesterday's message (a C7.8 on 26-Dec-2015 at 05:01 UT). More C-class flares are expected over the next 24 hours, with a reasonable chance for a low M-class flare. The position of NOAA 12473 on 26-Dec-2015 at 20:30 UT is: S22E11, ( -172", -330" ) 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 low level. NOAA 12473 remains the largest and most complex region on the visible disk. This region grew in spot area marginally over the past 24 hours, maintaining number of spots and a beta-gamma/E-type sunspot group designation. NOAA 12473 has continued to produce C-class events, while the largest flare since the last message came from decaying region 12472 (a C6.9 flare on 25 Dec-2015 at 16:59 UT). More C-class activity is expected, with a chance for an isolated low-to-mid M-class flare. The position of NOAA 12473 on 25-Dec-2015 at 22:00 UT is: S22E23, ( -356", -334" ) 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 is low-to-moderate. NOAA region 12473 grew significantly in spot area over the previous 24 hours. This region is now classified as a beta-gamma/E-type sunspot group and again produced the largest flare since the last message - an M1.1 on 24-Dec-2015 at 01:49 UT. Further C-class activity is expected, with a good chance for additional low-to-mid M-class flares. The position of NOAA 12473 on 24-Dec-2015 at 23:30 UT is: S23E36, ( -533", -356" ) 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 moderate level. NOAA 12473 continued to grow in spot area over the past 24 hours, displaying a beta-delta/D-type classification before producing the largest flare of the period (an M4.7 on 23-Dec-2015 at 00:23 UT). However, this region may have now lost its delta-spot configuration because of the opposite polarity umbrae no longer having a common penumbra. More C-class activity is expected, with a good chance for another low-to-mid M-class flare. The position of NOAA 12473 on 23-Dec-2015 at 17:00 UT is: S23E53, ( -717", -363" ) 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 is moderate. NOAA region 12470 has decayed over the past 24 hours. Yesterday's target region is now designated as NOAA 12472 and was first classified as an alpha/H-type sunspot group. This region now appears to have at least a beta magnetic class, with extensive trailing plage. In the past 24 hours, another region rotated over the South East limb and is designated as NOAA 12473. This region has grown since becoming visible and produced the largest flare since the last message (an M1.6 on 22-Dec-2015 at 03:15 UT). NOAA 12473 was initially classified as a beta/C-type sunspot group, but this should be revised to (at least) a D-type region as the leading and trailing spots each have mature penumbrae. More C-class activity is expected, with a good chance for additional low-to-mid M-class flares. The position of NOAA 12473 on 22-Dec-2015 at 17:00 UT is: S22E70, ( -850", -356" ) 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.
