MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Mar '12

MM#009 Default HESSI Target Dear RHESSI Collaborators, Old NOAA 1429 has returned to the visible solar disk displaying a nearly spotless reversed polarity plage with a well developed filament located on the region's magnetic inversion line. It was the source of a few B-class events and a C-class event since the last message. No significant flare activity expected in the next 24 hour period. The position of the target on March 31 at 7:30 UT is: N19E68 (Solar X = -843", Solar Y = 350") 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, Old NOAA 1429, has appeared to have returned to the visible disk significantly decayed but it is still too close to the limb to thoroughly ascertain its magnetic configuration and sunspot group. The region was the source of numerous B-class events and a C1.4 event at 03/29/16:40 UT. Additional minor events expected with the chance of an isolated M-class event in the next 24 hour period. The position of the target on March 30 at 13:00 UT is: N19E80 (Solar X = -895", Solar Y = 329") 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 northeast limb target region (Old NOAA 1429) was the source of two limb occulted C-class events in the past 24 hour period. The largest was a C7.7 at 03/29/09:53 UT. Additional C-class events expected with a good chance of an M-class event as well in the next 24 hours. The approximate position of the target region on March 29 at 13:30 UT is: N19E87 (Solar X = -907", Solar Y = 316") 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 will switch from NOAA 1442 to the northeast limb. Old flare productive NOAA 1429 should return to the visible disk sometime during the next 24 hour period. The chance of an M-class event in the next 24 hours is significantly greater. The approximate position of the target on March 28 at 14:00 UT is: N18E88 (Solar X = -914", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target EFR, now re-numbered NOAA 1442, produced C-class activity in the past 24 hours. The largest was a C2.7 at 03/26/23:38 UT. The largest event of the period was a C5.3 at 03/27/03:08. Its source region was NOAA 1444 located just north of 1442. Both regions are maintaining simple beta magnetic configurations. No significant flare activity expected from the visible disk regions in the next 24 hour period. Old NOAA 1429 will return to the visible disk in the next few days. It has continued to be very active during its far side transit. The position of NOAA 1442 on March 27 at 13:00 UT is: N12W09 (Solar X = 147", Solar Y = 308") 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 will switch to an EFR located just south of NOAA 1444 (N19E05). The EFR has bright H-alpha plage, an arch-type-filament system and a cluster of many small spots. It is currently classified a simple beta magnetic configuration. If possible include NOAA 1444 within your F-O-V. No significant flare activity expected in the next 24 hour period. The position of the target on March 26 at 10:00 UT is: N12E10 (Solar X = -164", Solar Y = 284") 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 11444 and NOAA 11445 have each produced a C-class flare in the last 24 hours. NOAA 11445 maintains its E-type/beta configuration and remains the dominant sunspot group on the visible hemisphere, and shall continue to be the target region. Further C-level activity likely with chance for an isolated low M event. The position of NOAA 11445 on 25-Mar-2012 at 09:30 UT is: S24E57, ( -740", -332" ) 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, A new region has emerged on the southeast limb and was the source of an M1 flare at 19:34 UT yesterday. The region is designated NOAA 11445 and has an E-type sunspot group with a beta configuration. Further C-level activity expected as the region rotates on to the disk with chance for another low M-class flare. The position of NOAA 11445 on 24-Mar-2012 at 11:00 UT is: S24E70, ( -829", -354" ) 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 NOAA 11440 now in decay. The new target region shall be an emerging flux region in the northeast quadrant designated NOAA 11442. The region appears to have a beta-gamma magnetic configuration with an east-west polarity inversion line and may produce some low to intermediate level events if it continues to develop. The position of NOAA 11442 on 23-Mar-2012 at 12:00 UT is: N13E42, ( -629", 299" ) 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 emerging flux region in the southwest quadrant has now been designated as NOAA 11440. The region is classified as a beta-gamma-delta region due to some polarity mixing in the trailing sunspot but still maintains a low sunspot area. Several low C-class flares were produced as the region emerged indicating that further intermediate level activity is likely. The position of NOAA 11440 on 22-Mar-2012 at 12:30 UT is: S26W31, ( 452", -331" ) 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.
