MM#009 Default HESSI Target
by Max Millennium Chief Observer 21 Apr '11

21 Apr '11

Dear RHESSI Collaborators, Solar activity remains at low levels. NOAA 11193 was the source of a C1.5 flare at 17:38 UT yesterday. A newly numbered region on the southeast limb, NOAA 11196, produced a C4.0 flare at 19:30 UT and shall be the new target region. Chance for further mid-C-level activity as the region rotates onto the disk. Also include NOAA 11195 in your field of view if possible. The position of NOAA 11196 on 21-Apr-2011 at 08:30 UT is: S27E64, ( -765", -399" ) 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, Quiet-Sun conditions continue. The target region NOAA 11193 has remained quiescent since the last message. The newly numbered region, NOAA 11195, in the southeast quadrant was the source of a C1.1 flare at 03:47 UT today, although its magnetic configuration is uncertain at this time. NOAA 11193 shall remain the target for a further 24 hours with chance of an isolated C-level event. The position of NOAA 11193 on 20-Apr-2011 at 08:30 UT is: N17W13, ( 209", 360" ) 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 low. NOAA 11190, now on the eastern limb, has decayed significantly over the past 24 hours. The new target region shall be NOAA 11193 which is crossing the central meridian. This region has a bipolar configuration with a strong leader spot, and was the source of a C1.5 flare at 18:55 UT yesterday. Chance for further isolated C-level events. The position of NOAA 11193 on 19-Apr-2011 at 08:30 UT is: N17W00, ( 3", 364" ) 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 has diminished as NOAA 11190 has begun to decay. The region continues to produce B-level activity, as well as a C1.8 flare at 03:18 UT. There have also been C1 flares from NOAA 11193 and an unnumbered region on the southeast limb. NOAA 11190 shall continue to be the target region for another 24 hours as it approaches the northwest limb. Further B-level activity expected with chance for an isolated C-class flare. The position of NOAA 11190 on 18-Apr-2011 at 08:30 UT at UT is: N14W58, ( 789", 276" ) 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 target region NOAA 11190 has continued to produce low C-level activity over the past 24 hours, including a C5.0 flare at 13:51 UT on 16-Apr-2011. The region is now classified as a beta-gamma region due to some mixed polarity in its trailing edge. Further C-level activity expected. The position of NOAA 11190 on 17-Apr-2011 at 08:30 UT is: N14W45, ( 660", 293" ) 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 target region NOAA 11190 was the source of an M1.3 flare yesterday at 17:02 UT, in addition to several C-class events. The region continues to develop in size but has retained a beta magnetic configuration. Further C-level activity expected with chance for another isolated M-class flare. The position of NOAA 11190 on 16-Apr-2011 at 09:30 UT is: N13W32, ( 492", 291" ) 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 low C-level. NOAA 11193 has remained quiescent since the C4.9 flare yesterday. At this time the target region shall revert back to NOAA 11190 which has been the source of numerous high B- and low C-class events over the past 24 hours as it continues to develop. Further intermediate level activity expected. The position of NOAA 11190 on 15-Apr-2011 at 09:30 UT is: N13W20, ( 316", 301" ) 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 elevated with numerous low C-class events occurring over the past 24 hours. The largest of these was a C4.9 at 05:20 UT today from NOAA 11193 which is now on the eastern limb. NOAA 11193 shall be the new target region and is expected to produce further C-level activity. If possible, also include NOAA 11191 in your field of view. The position of NOAA 11193 on 14-Apr-2011 at 09:30 UT is: N17E65, ( -832", 317" ) 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, Activity has increased over the past 24 hours. NOAA 11191 has begun to rotate onto the east limb and so far consists of a large bipolar leading spot. As yet, the trailing spot is difficult to characterize as it has not fully rotated onto the disk yet. NOAA 11190 is at the central meridian and continues to experience flux emergence at its center, now classified as beta gamma. Although both of these regions have, and will continue to produce C class flares, we will select 11190 as today's target, until 11191 rotates further onto the disk. Further C and possibly M class activity possible today. The position of NOAA 11190 on 13-Apr-2011 15:30 UT is: N15E03 ( -48", 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, Activity levels have increased slightly with four C class flares in the past 24 hours - two from a region on the east limb and two from the newly numbered NOAA 11190 located in the north east quadrant. This AR is former NOAA 11172 and until yesterday was in its decay phase. There has been significant emerging flux within the center of the region and to the west of it and now contains six sunspots. This will be the target of opportunity today. The position of NOAA 11190 on 12-Apr-2011 15:30 UT is: N12E16 ( -263", 290" ) 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.
