MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, There were two C-class events since the last message. NOAA 1226 produced a C1.7 at 05/31/05:53 and NOAA 1227 produced a C1.8 at 05/31/04:43 UT. Both regions are slowly decaying. The target region will continue to be 1226 but if possible, include 1227 within your F-O-V. The position of NOAA 1226 on May 31 at 10:30 UT is: S21E36 (Solar X = -520", Solar Y = -330") 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 1226 and 1227 were the source of several C-class events since the last message. The largest was a C8.7 event at 05/29/21:15 UT. Its source region was NOAA 1227 located just east of NOAA 1226. Both regions have beta-gamma magnetic configurations. Additional C-class activity expected with a slight chance of an M-class event in the next 24 hours. If possible, include both 1226 and 1227 within your F-O-V. The position of NOAA 1226 on May 30 at 10:30 UT is: S21E48 (Solar X = -658", Solar Y = -330") The position of 1226/1227 on May 30 at 10:30 UT is: S20E55 (Solar X = -730", 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, Target region, NOAA 1226, was the source of countless C-class events and two M-class events (M1.1 at 05/28/21:50 and an M1.4 at 05/29/10:30 UT). The M1.4 event was associated with a large CME blasting off the east limb. 1226 has a D-type sunspot group with a beta-gamma magnetic configuration. C-class events certain with a good chance for another M-class event as well in the next 24 hours. A region located just east of 1226 at S19E75 appears to have reversed polarity. The position of NOAA 1226 on May 29 at 15:00 UT is: S21E60 (Solar X = -767", Solar Y = -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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region, now numbered NOAA 1226, was the source of numerous C-class events since the last message. The largest was a C8.3 at 05/28/03:15 UT. The region is currently classified as a D-type sunspot group with a beta magnetic configuration but there is a possible magnetic delta developing in the trailing portion of the region. C-class events expected with a good chance of an M-class event as well. If the delta develops, there is a chance of an M-class event = or > than M5. The position of NOAA 1226 on May 28 at 10:30 UT is: S18E68 (Solar X = -835", Solar Y = -286") 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 1223, produced a few B-class events since the last message. The target region will switch to a new region located on the SE limb. This region is too close to the limb to ascertain its magnetic configuration but it has bright H-alpha plage and is currently displaying active surging. B-class events expected with a good chance of C-class activity as well in the next 24 hours. The position of the SE limb target on May 27 at 14:45 UT is: S21E89 (Solar X = -884", Solar Y = -339") 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 activity increased somewhat with the rapid development later in the period of an EFR located in the SE quadrant. The EFR was the source of a C1.1 event at 05/25/21:03 and the C1.4 event at 05/25/21:58 UT. The region is still in growth phase. B-class activity probable with the chance of another C-class event in the next 24 hours. The position of the target EFR on May 26 at 06:15 UT is: S15E26 (Solar X = -403", Solar Y = -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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity is very low. There were only 4 low level B-class events in the past 24 hours. Two were produced by target region NOAA 1220 before it rotated over the west limb. The other two B-class events were produced by new target region NOAA 1218. 1218 is currently spotless but is the brightest H-alpha plage on the visible disk. Solar flare activity is expected to continue at a very low level with no change expected anytime soon. The position of NOAA 1218 on May 25 at 10:30 UT is: S16W20 (Solar X = 312", Solar Y = -239") 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. The largest events in the past 24 hours were only two minor B-class events from target region NOAA 1220 on the west limb. Solar flare activity is expected to continue at a very low level for the next 24 hours. The position of NOAA 1220 on May 24 at 04:30 UT is: N13W82 (Solar X = 914", Solar Y = 216") 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. The target EFR, now numbered NOAA 1220, is currently classified as a small B-type sunspot group with a beta magnetic configuration. Only low level B-class activity expected in the next 24 hours. The position of NOAA 1220 on May 23 at 10:30 UT is: N14W71 (Solar X = 870", Solar 238") 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. The target will switch to an EFR located in the northwest quadrant. The EFR is displaying bright H-alpha plage and dark arch-type filaments. It currently has a simple beta magnetic configuration. B-class events possible with a chance of a C-class event in the next few days if development continues. The position of the target region on May 22 at 12:30 UT is: N12W56 (Solar X = 771", Solar Y = 214") 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.
