MM#009 Default HESSI Target
by Max Millennium Chief Observer 17 Mar '11

17 Mar '11

Dear RHESSI Collaborators, The level of solar activity is now low. NOAA region 11169 has maintained a beta-gamma magnetic configuration as it approaches the NW limb. This region has continued to produce C-class flares, the largest of which was a long-duration C3.7 event at 17:52 UT on 16-Mar-2011. Further C-class activity is possible. The position of NOAA 11169 on 17-Mar-2011 at 16:00 UT is: N17W84, ( 917", 292" ) 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 region 11166 has now rotated up to the NW limb, with an observed decrease in the number of flares. NOAA regions 11166 and 11169 both display beta-gamma magnetic configurations, with 11169 being the source of an M1.0 event at 00:18 UT on 15-Mar-2011. C-class activity is expected, with a small chance of another low M-class event. The position of NOAA 11169 on 16-Mar-2011 at 15:30 UT is: N17W68, ( 859", 322" ) 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 1169, was the source of C-class activity and two M-class events since the last message. The largest M-class event was an M4.2 at 03/14/19:52 UT. The region has decayed somewhat after the M-class events but is maintaining a beta-gamma magnetic configuration with opposite polarity flux still located along the southwestern edge of the leading polarity penumbra. C-class activity expected with the chance of another M-class event. The position of NOAA 1169 on March 15 at 11:30 UT is: N18W54 (Solar X = 743", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1166 continues in decay phase. NOAA 1169 has added a small area of opposite polarity flux near the large leading penumbra. The default target will switch from 1166 to 1169 today. C-class activity probable with a slight chance of an isolated M-class event. The position of NOAA 1169 on March 14 at 11:30 UT is: N20W41 (Solar X = 596", Solar Y = 414") 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 1166 has continued in decay phase losing its complicated beta-gamma-delta magnetic classification. It has decayed to a simple beta magnetic configuration. NOAA 1169 increased its sunspot area but is also a beta configuration. 1166 produced a few C-class events since the last message. Both 1166 and 1169 should produce C-class events with a slight chance of an isolated M-class event in the next few days. The position of NOAA 1166 on March 13 at 16:30 UT is: N09W62 (Solar X = 843", Solar Y = 206") 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 1166 has continued to slowly decay but remains a beta-gamma-delta magnetic class. It produced numerous C-class events again plus an M1.3 event at 03/12/04:43 UT. 1166 will continue to produce C-class activity with a good chance of another M-class event in the next 24 hours. The position of NOAA 1166 on March 12 at 16:30 UT is: N09W49 (Solar X = 721", Solar Y = 228") 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

11 Mar '11

MM#003 Major Flare Watch Dear RHESSI Collaborators, We will continue the Major Flare Watch on NOAA 1166 for at least another 24 hours. 1166 has decayed somewhat but is maintaining a beta-gamma-delta magnetic classification and bright H-alpha plage. 1166 produced several C-class events and an M1.1 event at 03/10/22:41 UT. NOAA 1169 (N20W03) appears to be forming a small magnetic delta configuration in its leading portion. 1166 and 1169 are expected to produce C-class events with the chance of an M-class event as well. An isolated M-class =>M5 is also possible in the next 24 hours. The position of NOAA 1166 on March 11 at 11:30 UT is: N09W33 (Solar X = 521", Solar Y = 251") 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 1166, was the source of a major X1.5 flare late yesterday at 23:23 UT. 1166 developed rapidly during the day increasing its spot count, spot area and magnetic complexity forming a strong delta configuration within its central portion. If the region retains its magnetic complexity, an event => than M5 is possible. The position of NOAA 1166 on March 10 at 11:30 UT is: N09W19 (Solar X = 311", Solar Y = 264") 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

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, NOAA 1165, was very active yesterday during west limb passage. It was the source of numerous C-class events and an M4.4 event at 03/08/18:28 UT and an M1.5 at 03/08/20:16 UT. The target will switch to NOAA 1166 today. 1166 produced an M1.7 event at 03/09/11:07 UT. 1166 has a beta-gamma-delta magnetic configuration. 1166 and former target 1164 are capable of producing M-class events. There also remains a slight chance of a mid-level M-class event. The position of NOAA 1166 on March 09 at 11:30 UT is: N11W08 (Solar X = 132", Solar Y = 302") 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 1164 was the source of a long duration M3.7 x-ray event at 02/07/20:01 UT. This flare was associated with a strong Type II radio event, a fast full halo CME, and a minor proton event. The largest x-ray event since the last message was an M5.3 at 03/08/10:44 UT. The M5.3 source region was NOAA 1165 on the SW limb. This region emerged on March 3 on the northern edge of NOAA 1165. It entered a very rapid growth phase on March 6 and quickly developed a complex beta-gamma-delta magnetic classification. There appears to be a strong delta configuration located in the trailing portion. 1165 is currently displaying bright H-alpha plage and surges as it rotates over the west limb. The target will switch from 1164 to 1165 today. Another large event is possible from 1165 before it rotates off the visible disk. 1164 (N24W66) and 1166 (N11E05) are also capable of producing an event equal to or greater than M5. The position of the target (NOAA 1165) on March 08 at 11:30 UT is: S20W85 (Solar X = 904", Solar Y = -318") 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.
