MM#009 Default HESSI Target
by Max Millennium Chief Observer 25 May '11

25 May '11

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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity is extremely low. The largest x-ray event was a B1.6 at 05/21/07:42 UT from target region NOAA 1214. No increase in solar flare activity is expected anytime soon. The position of NOAA 1214 on May 21 at 15:30 UT is: S24W79 (Solar X = 850", Solar Y = -379") 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 extremely low. All regions on the visible disk with sunspots have simple alpha magnetic configurations. No significant change in the low level of solar activity is expected anytime soon. The default target will continue to be NOAA 1214. The position of NOAA 1214 on May 20 at 15:30 UT is: S24W65 (Solar X = 786", Solar Y = -372") 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 largest x-ray event yesterday was a long duration C2 at 18:30 UT from NOAA 1208 near the northwest limb. The event was associated with a west limb CME. The target region (NOAA 1218) has a simple alpha sunspot group. We will switch to NOAA 1214. Solar flare activity is expected to be very low today. The position of NOAA 1214 on May 19 at 15:30 UT is: S24W51 (Solar X = 674", Solar Y = -365") 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 1214 is significantly decaying. The target will switch to a region rotating over the southeast limb at approximately S16. This region was the source of a B-class event and the C1.2 event at 05/18/12:58 UT. The region is too close to the limb to ascertain its magnetic complexity. Another B-class event probable with a chance of another C-class event as well. The position of the target region on May 18 at 13:00 UT is: S16E80 (Solar X = -899", Solar Y = -255") 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 1208 continues to decay as it approaches west limb passage. The target will switch to the twin beta regions located in in the southwest (NOAA 1214). 1214 was the source of a few B-class events since the last message. No significant solar flare activity is expected in the next 24 hours. The position of NOAA 1214 on May 17 at 15:30 UT is: S24W19 (Solar X = 283", Solar Y = -352") 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 1208, was the source of a C4.8 event at 05/15/23:34 UT. It also produced a B5.7 event at 05/16/10:40 UT. 1208 is now in decay phase but it is still possible that it could produce another B-class event with a slight chance of a C-class event in the next 24 hours. The position of NOAA 1208 on May 16 at 10:30 UT is: N11W54 (Solar X = 755", 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.
