MM#009 Default HESSI Target
by Max Millennium Chief Observer 20 Apr '12

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target region will switch today to a strong EFR located in the southeast. Former target region, NOAA 1463, is maintaining a weak beta-gamma magnetic configuration but continues in decay phase. The target region could produce C-class activity in the next 24 hour period. Several other NOAA regions (1459,1460,1462 and 1463) on the visible disk also have the potential to produce C-class events. The position of the EFR target on April 20 at 13:00 UT is: S17E47 (Solar X = -670", Solar Y = -223") 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 numbered NOAA 1463, produced C-class activity in the past 24 hour period. 1463 is now in decay phase but has retained minor mixed polarities. Additional C-class events possible in the next 24 hours. NOAA regions 1459, S16E20, and 1460, N16E04 also have the potential to produce C-class events. The position of NOAA 1463 0n April 19 at 13:00 UT is: S26W44 (Solar X = 597", Solar Y = -361") 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 of choice today will switch from NOAA 1461 to a strong EFR located in the southwestern quadrant. This EFR was the source of 4 C-class events today The largest was a C8.9 at 04/18/12:39 UT. C-class events expected with the chance of an M-class event in the next 24 hour period. The position of the target EFR on April 18 at 12:30 UT is: S26W29 (Solar X = 418", Solar Y = -349") 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, now numbered NOAA 1461, was the source of an M1.7 limb event at 04/16/17:40 UT. The event produced a very impressive flare spray off the northeast limb. The region also produced two C-class events. 1461 is currently an unimpressive plage with an H-type/alpha sunspot group. Additional C-class activity is possible in the next 24 hour period. The position of NOAA 1461 on April 17 at 03:30 UT is: N12E75 (Solar X = -904", Solar Y = 221") 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 NE limb target region was the source of the C1.8 event at 04/16/00:45 UT. The region is still too close to the limb to ascertain its sunspot group type and magnetic classification. Another C-class event is possible in the next 24 hours. The approximate position of the target on April 16 at 00:30 UT is: N12E88 (Solar X = -935", Solar Y = 201") 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 from NOAA 1455 to a region located just beyond the northeast limb. This region was the source of two limb occulted C-class x-ray events. The largest was a C2.7 at 04/15/01:40 UT. Additional C-class events are possible in the next 24 hour period. The approximate position of the target on April 15 at 01:30 UT is: N11E88 (Solar X = -938", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, NOAA 1455, was the source of numerous B-class events since the last message. The largest was a B9.8 event at 04/14/00:47 UT. 1455 is maintaining a D-type/beta-gamma sunspot group. B-class activity is expected with the chance of a C-class event in the next 24 hour period. The position of NOAA 1455 on April 14 at 13:00 UT is: N07W27 (Solar X = 432", Solar Y = 199") 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 region 11455 has continued to emerge new flux in the last 24 hours. This region has increased in spot area and number of spots, and produced B-class activity. NOAA 11455 is now classified as a beta/D-type sunspot group, with the trailing positive polarity spots still developing mature penumbrae. More B-class activity is expected, with a chance for C-class activity if 11455 continues to undergo flux emergence. The position of NOAA 11455 on 13-Apr-2012 at 11:00 UT is: N06W11, ( 184", 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, Yesterday's target is now designated as NOAA region 11455. This region has merged some smaller spots into more substantial leading spots, with additional spot emergence. NOAA 11455 was the source of several B-class events and has a beta/C-type sunspot group classification. More B-class activity is expected in the next 24 hours, with a chance for a C-class flare if 11455 continues to emerge new flux. The position of NOAA 11455 on 12-Apr-2012 at 09:00 UT is: N07E03, ( -50", 213" ) 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 level of solar activity remains low. Yesterday's target was the source of 2 B-class flares and is now designated as NOAA 11454 with a beta/C-type sunspot group classification. A newly spotted region appeared in the North East quadrant a few hours before today's NOAA number designations were issued. This region has experienced bipolar flux emergence within pre-existing negative plage field, displaying some polarity mixing between the primary leading and trailing spots. B-class events are probable in the next 24 hours, with a chance for C-class activity if this new region continues to emerge new flux. The approximate position of this region on 11-Apr-2012 at 09:30 UT is: N08E16, ( -263", 226" ) 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.
