MM#009 Default HESSI Target
by Max Millennium Chief Observer 20 Apr '13

20 Apr '13

Dear RHESSI Collaborators, Newly emerged active region NOAA 11726 has been the source of several C1 flares over the past 24 hours and shall be the new target region. The region appears to be quadrapolar in nature with polarity mixing in the trailing portion. Good chance for further low-to-intermediate level activity as the region continues to develop. The position of NOAA 11726 on 20-Apr-2013 at 09:00 UT is: N13E02, ( -32", 298" ) 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, NOAA 11719 was the source of an unexpected over-the-limb C6.5 flare at 17:56 UT yesterday but otherwise activity has remained at low levels. The target region NOAA 11723 continues to decay and maintains its beta/D-type configuration. No significant activity expected over the next 24 hours. The position of NOAA 11723 on 19-Apr-2013 at 09:00 UT is: S16W21, ( 333", -185" ) 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, NOAA 11719 has produced additional low C-class flares as it approaches the western limb. The target region NOAA 11723 has remained quiescent and has begun to decay in its trailing portion and is now classified as a beta region. Slight chance for some isolated low-level events. The position of NOAA 11723 on 18-Apr-2013 at 09:00 UT is: S18W10, ( 158", -211" ) 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, NOAA 11719, now on the western limb, was the source of several low-level events since the last message, including a C3.5 flare at 21:17 UT yesterday. The target region NOAA 11723 remains unchanged in terms of size and complexity, and has been relatively quiet. Slight chance of increased activity over the next 24 hours. The position of NOAA 11723 on 17-Apr-2013 at 09:00 UT is: S17E04, ( -61", -193" ) 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, NOAA 11718 is now over the western limb. Solar activity continues at the low C-level with several events emanating from NOAA 11723 in the southern hemisphere which shall be the new target region. NOAA 11723 has shown signs of flux emergence over the past 24 hours and is now classified as a beta-gamma region. Further C-level activity likely. The position of NOAA 11723 on 16-Apr-2013 at 09:00 UT is: S18E15, ( -233", -211" ) 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 low levels with no C-class flares over the past 24 hours. The target region NOAA 11718 retains its beta-gamma configuration as it approaches the western limb but continues to decay. Slight chance of an isolated intermediate level event before west limb passage. The position of NOAA 11718 on 15-Apr-2013 at 09:00 UT is: N20W75, ( 869", 348" ) 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, Solar flare activity is low. The largest x-ray event in the past 24 hours was a C1.4 at 04/13/19:53 UT produced by NOAA 1718. 1718 is now decaying but is currently maintaining its somewhat complex beta-gamma magnetic configuration. B-class events expected with a chance of a C-class event and only a slight chance of an isolated M-class event in the next 24 hours. The position of NOAA 1718 on April 14 at 13:00 UT is: N21W66 (Solar X = 816", Solar Y = 377") 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 1719, N11W22, has decayed significantly losing its magnetic delta configuration. It was the source of only minor C-class events in the past 24 hours. NOAA 1718 produced an isolated M3.3 event at 04/12/20:38 UT. 1718 has decayed slightly since the M-class event but remains a D-type/beta-gamma region with the brightest plage on the visible disk. The target will switch from 1719 to 1718 today. There is a chance of another M-class event in the next few days. The position of NOAA 1718 on April 13 at 13:00 UT is: N21W54 (Solar X = 723", Solar Y = 394") 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

MM#003 Major Flare Watch Dear RHESSI Collaborators, The magnetic delta configuration located in the trailing spot in target region NOAA 1719 has decayed somewhat after the M6.5 event yesterday but the region is maintaining its large E-type/beta-gamma-delta sunspot group. Another event =/>M5 is possible in the next few days if 1719 preserves its complex magnetic configuration. The position of NOAA 1719 on April 12 at 13:00 UT is: N10W08 (Solar X = 131", Solar Y = 260") 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 1719 was the source of an isolated M6.5 event at 04/11/07:16 UT. At this time we are implementing Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare). 1719 rapidly developed a magnetic delta configuration located in the southeastern portion of its reversed polarity D-type/beta-gamma sunspot group. We will switch to 1719 from NOAA 1718 today. 1718 is maintaining its D-type/beta-gamma sunspot group and is currently the brightest region on the visible disk. It is possible that 1719 will produce another major flare =/>M5 in the next few days. 1718 is also capable of producing an isolated M-class event. The position of NOAA 1719 on April 11 at 13:00 UT is: N10E05 (Solar X = -082", Solar Y = 262") 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.
