MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Aug '14

31 Aug '14

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 2149 continues to slowly decay but is maintaining mixed polarities and bright H-alpha plage. 2149 is producing C-class events. The largest since the last message was a long-duration C7.1 at 08/31/11:00 UT. NOAA 2152, S17E21, has grown significantly in the past few days and was also the source of C-class events in the past 24 hours. Both target region 2149 and 2152 have the potential to produce C-class events with a slight chance of an isolated M-class in the next 24 hour period. The position of NOAA 2149 on August 31 at 11:00 UT is: N09W57 (Solar X = 788", 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 2149 slowly added new small spots in the past 24 hours. Its magnetic classification is currently beta-gamma. 2149 was the source of C-class events since the last message. Additional C-class activity probable in the next 24 hour period. The position of NOAA 2149 on August 30 at 03:00 UT is: N09W36 (Solar X = 553", Solar Y = 053") 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 2146 is now located just beyond the northwestern limb. 2146 was the source of a limb occulted C4.3 event at 08/29/15:52. This event was associated with a flare spray and an eruptive prominence. 2146 has completed west limb passage. The new target region will be NOAA 2149. 2149 has an EFR located adjacent (south) of the large round leader sunspot. C-class events possible in the next 24 hours. The position of NOAA 2149 on August 29 at 17:00 UT is: N10W31 (Solar X = 483", Solar Y = 064") 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 2146 is in decay phase but is maintaining its magnetically complex beta-delta configuration. C-class activity probable with the chance of an isolated M-class event before 2146 completes west limb passage. The position of NOAA 2146 on August 28 at 11:00 UT is: N07W79 (Solar X = 925", Solar Y = 092") 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 2146 has lost penumbral area but is retaining its beta-delta magnetic configuration. C-class events probable and an isolated M-class event possible with a slight chance of an event =/>M5 in the next 24 hour period. The position of NOAA 2146 0n August 27 at 11:00 UT is: N07W65 (Solar X = 855", Solar Y = 065") 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 2146 is mostly unchanged maintaining a magnetically complex D-type/beta-delta sunspot group. 2146 was the source of a few C-class events and the M3.9 event at 08/25/20:20 UT. C-class events certain with a good chance of another M-class event. There is also a chance of an event =/>M5 if 2146 develops additional magnetic complexity in the next 24 hours. The position of NOAA 2146 on August 26 at 11:30 UT is: N09W53 (Solar X = 750", Solar Y = 078") 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 Major Flare Watch target (NOAA 2151, S07E49) has been quiescent since the major M5.9 event at 08/24/12:17 UT. 2151 is the decayed return of flare-active old NOAA 2130. 2151 currently has a simple C-type/beta sunspot group. It appears that the M5.9 event was the last large flare from this region. The new target will be NOAA 2146. 2146 has displayed rapid flux emergence in the past 48 hours. The new flux is located adjacent (south) to the old large leader sunspot creating an interesting D-type/beta-delta magnetic configuration. 2146 was the source of C-class activity in the past 24 hours and the M2.0 event at 08/25/15:11 UT. C-class events probable with the chance of another M-class event in the next 24-48 hours. The position of NOAA 2146 on August 25 at 11:30 UT is: N09W40 (Solar X = 604", Solar Y = 059") 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
by Max Millennium Chief Observer 24 Aug '14

24 Aug '14

Dear RHESSI Collaborators, The level of solar activity is moderate-to-high. NOAA 12149 has shown signs of decay over the past 24 hours after decreasing in area. This region is classified as a beta-gamma/E-type sunspot group and has produced several C-class flares since yesterday's message, including a C5.5 flare on 24-Aug-2014 at 04:53 UT. NOAA 12151 has been numbered after rotating over the South East limb and has already been the source of an M5.9 flare (on 24-Aug-2014 at 12:00 UT). This appears to be the return of the active region previously designated as 12130 that displayed a beta-gamma-delta classification on the last disk transit and produced two M-class flares. We are now initiating a MM#003 Major Flare Watch because 12151 produced a flare above the M5 level. More C-class activity is expected over the next 24 hour period, with a chance for more flaring above the M5 level. The position of NOAA 12151 on 24-Aug-2014 at 13:00 UT is: S07E64, ( -846", -166" ) 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 12149 has grown in spot area and number of spots with rotating onto the visible disk. With now being further from the limb, this region is accurately classified as a beta-gamma/E-type sunspot group. 12149 has continued to produce flares since yesterday's message, including a C3.5 flare on 23-Aug-2014 at 01:49 UT. More C-class activity is expected over the next 24 hours, with a good chance for another M-class flare. The position of NOAA 12149 on 23-Aug-2014 at 13:00 UT is: N12E56, ( -769", 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, Solar activity is at a moderate level. Yesterday's target region has been designated as NOAA 12149. Since yesterday's message this region has continued to produce many C-class flares and an M1.2 flare (on 22-Aug-2014 at 06:18 UT). NOAA 12149 is classified as a beta/C-type sunspot group, but is still too close to the limb to be accurately determined. More C-class activity is expected over the next 24 hours, with a good chance for another M-class flare. The position of NOAA 12149 on 22-Aug-2014 at 16:30 UT is: N12E68, ( -861", 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.
