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

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1147 added a few trailing polarity spots but retains a simple C-type/beta sunspot group. 1147 continues to produce numerous B-class events. Additional B-class events expected with a slight chance of an isolated C-class event today. The position of NOAA 1147 on January 17 at 15:30 UT is: N27E56 (Solar X = -712", Solar Y = 482") 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 1147 has been mostly quiet since east limb passage. It was the source of several minor B-class events. The largest was a B5.7 at 01/15/23:48. Its current magnetic configuration appears to be a simple beta. 1147 still has the potential to continue producing B-class events with a chance of a C-class event. The position of NOAA 1147 on January 16 at 18:30 UT is: N24E69 (Solar X = -832", Solar Y = 421") 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 target region was the source of 10 B-class events and a C1.1 event at 01/15/14:19 UT. Bright plage and a leader sunspot are now visible on the NE limb. The region is still too close to the limb to ascertain its magnetic complexity. Another C-class event probable today with even a slight chance of a low-level M-class event in the next few days. The position of the target on January 15 at 11:00 UT is: N24E85 (Solar X = -888", Solar Y = 402") 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 increasing. A region located just behind the NE limb was the source of two C-class events with associated CMEs. This active region was also the source of a large CME on January 13. The largest C-class event was a C1.6 at 01/14/03:30 UT. Another C-class event is possible today. The approximate position of the target on January 14 at 15:00 UT is: N23E88 (Solar X = -898", Solar Y = 383") 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 1140, was the source of a few B-class events since the last message. The largest was a B3.4 at 01/13/09:19 UT. 1140 has now completed west limb passage. The visible solar disk is very quiet. The only region with spots is the new target (NOAA 1146). Solar flare activity is expected to be very low today. The position of NOAA 1146 on January 13 at 17:30 UT is: N24E09 (Solar X = -139", Solar Y = 464") 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 very low. The target region is now located on the west limb. Minor B-class activity is possible today. The position of NOAA 1140 on January 12 at 16:00 UT is: N33W83 (Solar X = 811", Solar Y = 537") 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 1140 added a few sunspots located in its trailing polarity portion. Low-level B-class events probable today. The position of NOAA 1140 on January 11 at 14:00 UT is: N32W69 (Solar X = 772", Solar Y = 537") 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 1140, produced a few B-class events since the last message. The largest B-class event was a B4.6 at 01/10/10:28 UT. Additional B-class events are probable today. The position of NOAA 1140 on January 10 at 16:30 UT is: N32W58 (Solar X = 702", Solar Y = 547") 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 remains at a very low level. The target region, NOAA 1140, produced a minor B1.3 event at 01/09/13:51 UT. 1140 has decayed somewhat within its trailing polarity portion. Solar flare activity is expected to continue at very low levels. A B-class event is still possible today. The position of NOAA 1140 on January 9 at 17:30 UT is: N33W46 (Solar X = 589", Solar Y = 570") 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. NOAA 1139 (S27W84) produced a B2.5 event at 01/08/09:23 UT. Target region 1142 (S14W55) continues to decay. We'll switch to new target NOAA 1140. 1140 has an unusual E-W magnetic inversion line with small positive polarity trailer spots located north of its large negative polarity leader sunspot. Solar flare activity is expected to remain at a low level. A B-class event is possible today. The position of NOAA 1140 on January 8 at 17:30 UT is: N33W34 (Solar X = 458", Solar Y = 577") 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.
