MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 May '13

31 May '13

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity continues at a very low level. All regions on the visible solar disk are in decay phase. The most active region since the last message was NOAA 1756, S18W81. 1756 was the source of two minor C-class events. The target region NOAA 1760 has a somewhat unusual east-west magnetic inversion line and the brightest H-alpha plage on the disk. No significant solar flare activity expected anytime soon. The position of NOAA 1760 on May 31 at 13:00 UT is: N12E43 (Solar X = -633", Solar Y = 205") 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. All regions on the visible solar disk are magnetically simple. Target region NOAA 1756, S19W61, has significantly decayed and has been quiescent during the past 24 hours. The target will switch from 1756 to NOAA 1760 today. 1760 is a recently emerged small bright compact plage with a B-type/beta sunspot group. 1760 has been producing a few minor C-class events over the past two days. The most recent was a C2.9 at 05/29/22:36 UT. No noteworthy events are expected in the next 24 hours. The position of NOAA 1760 on May 30 at 13:00 UT is: N10E55 (Solar X = -765", Solar Y = 172") 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 continues at low levels. There were two minor C-class events since the last message. NOAA 1756 produced a C1.2 at 05/29/07:36 UT and a new small compact region located at N11E74 was the source of a C1.5 event at 05/29/02:18 UT. Although target region 1756 is displaying significant decay, it will remain the target for another 24 hours. No noteworthy solar flare activity expected in the next 24 hour period. The position of NOAA 1756 on May 29 at 13:00 UT is: S20W46 (Solar X = 641", Solar Y = -314") 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 continues at a very low level. All regions on the visible solar disk are magnetically simple. The target region NOAA 1756 is decaying but remains a very extended F-type/beta region. No significant flare events expected in the next 24 hours. The position of NOAA 1756 on May 28 at 13:00 UT is: S20W34 (Solar X = 499", Solar Y = -310") 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. There were only two minor C-class events since the last message. Both events were produced by target region 1756. 1756 has a large extended F-type sunspot group but its magnetic classification is now a simple beta. There remains a slight chance of another C-class event in the next 24 hours. The position of NOAA 1756 on May 27 at 13:00 UT is: S20W21 (Solar X = 320", Solar Y = -307") 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 is at a low level. The largest event over the previous 24 hours was a C3.8 on 26-May-2013 at 09:57 UT released by yesterday's target (NOAA 11756). Although the region exhibits minor signs of decay, it shows the largest area (290 microhemispheres) and complexity (beta-gamma/Ehi) of the regions on disk. Further low C-class activity is expected with a chance for an isolated high C-class flare. The position of NOAA 11756 on 26-May-2013 at 18:00 UT is: S20W09, ( 137", -305" ) 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 is at a low level. The largest event over the previous 24 hours was a C2.1 flare on 25-May-2013 at 10:49 UT released by yesterday's target (NOAA 11756). The region shows the decay of intermediate spots in the leading portion and minor intermediate spot emergence in the following portion. The classification of NOAA 11756 remains unchanged (beta-gamma/Ehi). Further low C-class activity is expected with a chance for an isolated high C-class flare. The position of NOAA 11756 on 25-May-2013 at 16:30 UT is: S20E06, ( -94", -303" ) 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 is at a low level. Yesterday's target (NOAA 11756) produced the largest event over the previous 24 hours (a C3.4 flare on 23-May-2013) and has continued to produce low C-class activity. NOAA 11756 shows minor evidence for a gamma configuration and its polarity separation line appears to be weakening. However, its sunspot classification has changed from Dsi to Ehi. Further C-class activity is expected with a chance for an isolated high C-class flare. The position of NOAA 11756 on 24-May-2013 at 18:30 UT is: S20E17, ( -260", -302" ) 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 is at a low level. Yesterday's target (NOAA 11755) has produced low C-class activity over the previous 24 hours and the main polarity separation line between the two adjacent spots in the trailing portion has weakened. There is only minor evidence for its gamma magnetic classification. The largest event over the previous 24 hours was a C3.9 flare on 23-May-2013 at 14:50 UT, released by NOAA 11756. NOAA 11756 has undergone continued flux emergence and exhibits a clear gamma configuration. It was the source of multiple C-class flares over the previous 24 hours. Further C-class activity is expected with a chance for high C-class activity. The position of NOAA 11756 on 23-May-2013 at 18:30 UT is: S20E31, ( -459", -303" ) 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 is at a moderate to high level. The largest event over the previous 24 hours was an M5.0 flare on 22-May-2013 13:32 UT released by NOAA 11745. The region exhibits a simple configuration (beta/Cao) and there is some evidence that it was destabilised by dynamics within the adjacent region, NOAA 11748. No further substantial activity is expected from NOAA 11745. A newly emerging region in the South-East quadrant has been designated NOAA 11756 and was responsible for multiple low C-class flares. The region shows evidence for a beta-gamma configuration. On the other hand, yesterdays target (now designated NOAA 11755) has continued to emerge, also shows evidence for a beta-gamma classification, and additionally exhibits a very strong polarity separation line. Because of this, NOAA 11755 will remain the target. Low C-class activity is expected with a chance for a high C-class event. The position of NOAA 11755 on 22-May-2013 at 18:00 UT is: N10E52, ( -738", 183" ) 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.
