21 May '11

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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target EFR, now numbered NOAA 1214, only produced one B-class event since the last message. The largest event (C1.3 at 05/15/14:25 UT) was produced by NOAA 1208. 1208 was also the source ot two B-class events. We'll switch to 1208 today with a possible switch back to 1214 (currently located at S24E08) tomorrow. There is additional new flux emerging just to the east of 1214 at S24E15. The position of NOAA 1208 on May 15 at 10:00 UT is: N10W43 (Solar X = 640", Solar Y = 197") 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. There is an emerging flux region located in the southeast quadrant. The EFR is currently displaying a beta magnetic configuration, bright H-alpha plage and a small arch-type filament system. We'll switch to the EFR from the spotless plage/filament target today. Only minor solar flare activity is expected at this time. The position of the target region on May 14 at 10:15 UT is: S24E21 (Solar X = -312", Solar Y = -348") 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 stable or in decay phase. The target will be the spotless plage located in the NE quadrant. This spotless region was the source of the C5.4 event on May 9 and the C1.8 event on May 12. The filament located along the region's main magnetic inversion line that was associated with the C1.8 event has reformed. There is only a very slight chance of another C-class event from the target region in the next 24 hours. The position of the target region on May 13 at 13:00 UT is: N17E44 (Solar X = -633", Solar Y = 311") 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 regions with sunspots on the visible disk are mostly unchanged or decaying. The spotless unnumbered region located at approximately N20E61 was the source of a C1.8 x-ray event at 05/12/12:15 UT. The event was most likely associated with a filament eruption. No significant solar flare events are expected in the next 24 hours. The position of NOAA 1210 on May 12 at 10:30 UT is: N19W27 (Solar X = 409", Solar Y = 351") 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.
