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

31 May '12

MM#009 Default HESSI Target Dear RHESSI Collaborators, The east limb target was the source of several C-class events in the past 24 hour period. The largest was a C2.5 event at 05/31/15:36 UT. The target area includes a young region with a beta magnetic configuration located just west of the east limb passage of the return of old NOAA 1476. Additional C-class events expected with a slight chance of an isolated M-class event in the next 24 hour period. The approximate position of NE limb target on May 31 at 15:30 UT is: N13E80 (Solar X = -909", Solar Y = 215") 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, All visible disk regions are either in decay phase or stable. The new target today will be a region on the northeastern limb near the location of the return of old NOAA 1476. The region was the source of the C1.1 event at 05/30/08:50 UT. Additional C-class activity possible in the next 24 hour period. The approximate position of the target on May 30 at 08:45 UT is: N13E89 (Solar X = -922", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1492, S13E32, continues to slowly decay and is quiet. We'll switch to NOAA 1490. 1490 is displaying flux emergence within its northern portion. A C-class event is possible in the next 24 hour period. The position of NOAA 1490 on May 29 at 00:30 UT is: S12E05 (Solar X = -081", Solar Y = -182") 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 has been at a low level in the past 24 hours. Target region, NOAA 1492, is currently an E-type/beta region. A C-class event is possible in the next 24 hour period. The position of NOAA 1492 on May 28 at 02:15 UT is: S12E44 (Solar X = -645", 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 1492, is maintaining a D-type/beta sunspot group. 1492 produced a long-duration C3.1 event at 05/27/05:51 UT. Another C-class event is possible in the next 24 hour period. The position of NOAA 1492 on May 27 at 02:00 UT is: S14E55 (Solar X = -755", Solar Y = -218") 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 1492, has an E-type/beta sunspot classification. It appears to be a region in decay phase but it is possible that it will produce a C-class event in the next 24 hour period. The position of NOAA 1492 on May 26 at 00:00 UT is: S13E65 (Solar X = -838", Solar Y = 204") 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, located northwest of NOAA 1486, developed slowly and is currently a D-type/beta region. The ERF was the source of a C1.1 event yesterday. We'll switch the target to a region rotating over the southeast limb that was the source of several C- and B-class events since the last message. Additional C-class events possible in the next 24 hours. The position of the SE limb region on May 25 at 13:00 UT is: S12E86 (Solar X = -925", Solar Y = -195" 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 1484, N11W60, continues in slow decay phase and was quiet. The target will switch to an EFR. This new region has several small spots with an interesting E-W magnetic inversion line and bright H-alpha plage. A C-class event is possible in the next 24 hour period. The position of the EFR target on May 24 at 11:00 UT is: N22W07 (Solar X = 108", Solar Y = 380") 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. The largest event in the past 24 hour period was a C1.1 at 05/23/00:27. Its source was target region NOAA 1484. 1484 has decayed somewhat since the last message. Another minor C-class event is possible in the next 24 hours. The position of NOAA 1484 on May 23 at 13:00 UT is: N10W53 (Solar X = 726", Solar Y = 181") 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. NOAA 1484 is mostly unchanged within its trailing portion but has decayed within its leading portion. 1484 is maintaining weak mixed polarities and is currently the brightest plage on the visible disk. A C-class event is possible in the next 24 hour period. The position of NOAA 1484 on May 22 at 15:00 UT is: N10W39 (Solar X = 589", Solar Y = 187") 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.
