MM#009 Default HESSI Target
by Max Millennium Chief Observer 10 Apr '12

10 Apr '12

Dear RHESSI Collaborators, Solar activity is at a low level. NOAA region 11450 has now rotated over the North West limb while several currently unnumbered regions are rotating over the South East limb. The region at ~S25 is likely to be the return of NOAA region 11440 and that at ~S13 is likely to be NOAA 11436 returning. The latter region appears to have a spot in its leading polarity faculae but the region is too close to the limb to determine a magnetic complexity. B-class activity is possible in the next 24 hours. The approximate position of this region on 10-Apr-2012 at 12:00 UT is: S13E80, ( -919", -198" ) 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, NOAA region 11450 has decreased in number of spots as it nears the North West limb, most likely due to foreshortening effects, but has maintained area because of the dominating leading spot. This region has an alpha/H-type sunspot group classification and produced a C2.6 flare on 9-Apr-2012 at 01:11 UT. Further B-class events are expected, with a chance of more C-class activity before 11450 rotates over the North West limb. The position of NOAA 11450 on 9-Apr-2012 at 09:00 UT is: N15W80, ( 911", 263" ) 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 remains at a very low level. NOAA region 11450 appears to be decaying as it approaches the North West limb. However, some of the decrease in spot area, number of spots, and complexity may be due to foreshortening effects. This region has a beta-gamma/C-type sunspot group classification. B-class events are possible in the next 24 hours, with a chance for a C-class event. The position of NOAA 11450 on 8-Apr-2012 at 09:00 UT is: N15W64, ( 833", 290" ) 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 very low level. NOAA region 11450 has increased in overall spot area as it approaches the North West limb, despite the continued decay of its trailing and intermediate spots. This region has maintained a beta-gamma/E-type sunspot group class in the last 24 hours. More B-class events are probable, with a chance for some C-class events. The position of NOAA 11450 on 7-Apr-2012 at 10:30 UT is: N16W51, ( 715", 326" ) 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, NOAA region 11450 has grown in spot area, number of spots, and complexity in the last 24 hours and is now classified as a beta-gamma/E-type sunspot group. This region has produced 3 C-class flares since the last message, the largest being a C3.1 flare on 5-Apr-2012 at 16:16 UT. NOAA 11450 now appears to be in decay phase, with the trailing spots decreasing in area. Further C-class events are possible in the next 24 hours. The position of NOAA 11450 on 6-Apr-2012 at 10:30 UT is: N15W37, ( 556", 328" ) 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, The level of solar activity remains very low. NOAA region 11450 has slowed in its evolution, but continues to develop more mature spots between the leading and trailing spots. This region has maintained a beta/D-type sunspot group classification and was the source of a C1.2 flare on 4-Apr-2012 at 16:17 UT. B-class activity is expected, with a chance for further C-class events in the next 24 hours. The position of NOAA 11450 on 5-Apr-2012 at 09:30 UT is: N17W24, ( 377", 371" ) 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, The level of solar activity remains very low. NOAA region 11450 has continued to grow slightly in spot area and number of spots. This region has maintained a beta magnetic configuration but increased in D-type sunspot group complexity by developing spots between the primary leading and trailing spots. NOAA 11450 was the source of 5 B-class events since the last message, the largest being a B7.1 flare on 4-Apr-2012 at 05:29 UT. Further B-class events are likely in the next 24 hours, with a chance for a C-class event. The position of NOAA 11450 on 4-Apr-2012 at 10:30 UT is: N16W10, ( 157", 364" ) 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 very low level. Two new bipolar regions have appeared on disk, while today's target will be NOAA 11450. This region has experienced some growth in spot area and number of spots and produced a B4.9 flare on 2-Apr-2012 at 21:53 UT. NOAA 11450 has a well-developed, compact bright EUV loop structure and an extensive region of bright plage between the leading and trailing spots. Further B-class events are possible, with a chance for a C-class event. The position of NOAA 11450 on 3-Apr-2012 at 09:30 UT is: N16E02, ( -29", 367" ) 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 very low. The large dark NE-SW filament located along the region's main magnetic inversion line has become activated especially in the southwestern portion. Increased internal motion could trigger a flare. The position of NOAA 1451 on April 02 at 11:00 UT is: N17E33 (Solar X = -501", Solar Y = 366") 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, No noteworthy solar flare activity in the past 24 hour period. Old NOAA 1429, now renamed NOAA 1451, is a region in decay phase with a small reversed polarity B-type/beta sunspot group. There are a few bright points adjacent to the region's large NE-SW filament. No significant flare activity expected in the next 24 hours. The position of NOAA 1451 on April 01 at 15:00 UT is: N17E44 (Solar X = -639", Solar Y = 354") 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.
