MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Aug '15

31 Aug '15

Dear RHESSI Collaborators, Solar activity has returned to a low level as NOAA 12403 rotates over the southwestern limb. 12403 produced a C2.2 event at 08/31/04:55 UT, which was associated with a weak CME. Occulted C-class activity is likely in the next 24 hours. The position of NOAA 12403 on August 31 at 14:35 UT is: S15W91 (Solar X = 917", Solar Y = -241") 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 2403 is now located mostly beyond the southwestern limb. 2403 produced a couple of C-class events and a very long-duration M1.4 event at 08/30/03:30 UT. No significant x-ray events expected in the next 24 hour period. The position of NOAA 2403 on August 30 at 12:30 UT is: S15W89 (Solar X =917", Solar Y = -417") 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 2403 is mostly unchanged maintaining its F-type beta-gamma-delta sunspot group. The magnetic delta configuration is located within the large leader sunspot. 2403 produced numerous C-class events and an isolated M2.1 event at 08/28/19:03 UT. C-class events expected with the chance of another M-class event before 2403 completes west limb passage. The position of NOAA 2403 on August 29 at 14:35 UT is: S15W78 (Solar X = 897", Solar Y = -267") 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 2403 continues to decay especially within its trailing portion. 2403 is currently classified as an F-type/beta-gamma sunspot with a weak magnetic delta configuration located in its leading polarity sunspot. 2403 was the source of numerous C-class events and an isolated M2.2 event at 08/28/13:16 UT. C-class events expected with the chance of another M-class event in the next 24 hour period. A major flare =/>M5 is now not likely. The position of NOAA2403 on August 28 at 12:30 UT is: S15W64 (Solar X = 825", Solar Y = -294") 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#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 2403 continues to slowly decay but is still displaying a somewhat complex F-type/beta-gamma-delta sunspot group. 2403 was the source of an isolated M2.9 event at 08/27/05:44 UT. Another isolated M-class event is possible with a slight chance of an M-class event =/>M5 in the next 24 hour period. The position of NOAA 2403 on August 27 at 14:35 UT is: S16W53 (Solar X = 730", Solar Y = -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.

MM#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 2403 continues to slowly decay but is maintaining its F-type/beta-gamma-delta classification. There are small opposite polarity flux elements located within both the large leading and following spot penumbrae. 2403 was only able to produce numerous C- and B-class events since the last message. The largest was a C9.5 at 08/26/13:53 UT. Although 2403 is currently losing its magnetic complexity somewhat, we will continue the MM#003 observing plan for another 24 hours. There is still a slight chance of an event =/>M5. The position of NOAA 2304 on August 26 at 12:30 UT is: S15W38 (Solar X = 566", Solar Y = -333") 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#003 Major Flare Watch Dear RHESSI Collaborators, NOAA 2403 is maintaining its large F-type/beta-gamma-delta sunspot group. There are small magnetic delta configurations located within the leading and trailing sunspots. 2304 was the source of an isolated M1.0 event at 08/24/17:46 UT. 2403 also produced countless C- and B-class events since the last message. C- and M-class events expected with the chance of an event =/>M5 in the next 24 hour period. The position of NOAA 2403 on August 25 at 14:35 UT is: S15W27 (Solar X = 417", Solar Y = -345") 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#003 Major Flare Watch Dear RHESSI Collaborators, Target region, NOAA 2403, was the source of an impulsive M5.6 event at 08/24/07:33 UT. 2403 also produced 13 C-class events since the last message. 2403 has decayed slightly following the M5 event but is still a large F-type sunspot group with a beta-gamma-delta magnetic configuration with the potential to produce another event =/>M5. At this time we are implementing Max Millennium coordinated observing plan #003. C-class events certain with a chance for a major flare =/>M5 in the next 24 hour period. The position of NOAA 2403 on August 24 at 14:35 UT is: S15W13 (Solar X = 206", Solar Y = -354") 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 at a moderate level. The largest event in the past 24 hours was an M3.5 at 08/22/21:19 UT produced by the target region NOAA 12403. 12403 was also the source of 8 C-class flares. 12403 is now classified as a beta-gamma-delta/E-type sunspot group, with increasing in sunspot area and number of spots slightly. It still has the potential to produce an isolated low M-class activity in the next 24 hours. The position of NOAA 12403 on August 23 at 14:35 UT is: S14W00 (Solar X = 0”, Solar Y = -340") 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 flare activity continues at moderate levels. Three low M-class flares (M1.1 at 08/21/19:10 UT, M1.2 at 08/22/06:39 UT, and M2.2 at 08/22/13:17 UT) were produced by the target region NOAA 12403 in the previous 24 hours. 12403 was also the source of several high level C-class events. 12403 continues to increase in sunspot area and number of spots, and remains classified as a beta-gamma/D-type sunspot group. It is continuing to mix polarities in its intermediate portion. Seems that the magnetic field in its leading portion becomes stronger. C-class flares are expected, with a potential of (high) M-class activity. The position of NOAA 12403 on August 22 at 14:35 UT is: S14E14 (Solar X = -223", Solar Y = -336") 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.
