MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Mar '15

31 Mar '15

Dear RHESSI Collaborators, Solar flare activity continues at low levels. The largest event was a C4.2 at 21:34 on March 30, which seems to be an occulted flare beyond the North West limb. Yesterday's target region NOAA 12305 has produced several low C-class events since the last message. 12305 maintains its D-type/beta magnetic classification. It is showing some flux emergence as well as mixed polarities in its leading portion. There is a chance for low C-class activity over the next 24 hour period. The position of NOAA 12305 on March 31 at 11:35 UT is: S10W58 (Solar X = 803", Solar Y = -108") 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 low levels. The largest event was a C4.7 at 01:38 UT on March 30 produced by NOAA 12303 (N18W91), which has rotated completely over the limb now. Yesterday's target region NOAA 12305 was the source of a C1.6 event at 18:45 on March 29. 12305 is classified as a D-type/beta magnetic configuration. Although 12305 is in decay phase, it is the most potential region on the solar disk to produce C-class activity in the next 24 hours. The position of NOAA 12305 on March 30 at 11:35 UT is: S10W43 (Solar X = 647", Solar Y = -85") 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 continues at low levels. NOAA 12303 (N18W85) was the source of numerous low C-class events before rotating off the visible disk. Yesterday's target region NOAA 12305 is mostly unchanged preserving an E-type/beta-gamma configuration. It continues to show some flux emergence in its leading portion. There is still a chance for C-class activity over the next 24-48 hours. The position of NOAA 12305 on March 29 at 11:35 UT is: S08W26 (Solar X = 418", Solar Y = -33") 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 low levels. NOAA 12309 (N14W86) was the source of a few C1 events as it was rotating over the west limb. Yesterday’s target region NOAA 12305 has produced two C2 events today. 12305 maintains its beta-gamma configuration with increasing in spot area and count somewhat. 12305 is showing some mixed polarities in its intermediate portion. It has the potential to produce further low C-class activity. The position of NOAA 12305 on March 28 at 12:35 UT is: S09W17 (Solar X = 278", Solar Y = -42") 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 has returned to low levels. There were three C1 events produced by the target region 12305 in the past 24 hours. 12305 has lost some of its spot area, number of spots, and magnetic complexity. It is classified as a C-type/beta-gamma configuration. Even though it is now in decay phase, 12305 will continue to be the target region. Additional low C-class events are likely within the next 24 hours. The position of NOAA 12305 on March 27 at 12:35 UT is: S08W02 (Solar X = 33", Solar Y = -20") 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 intermediate-to-low levels. The target region NOAA 12305 has produced a few low C-level events since the last message. 12305 continued to increase its sunspot area and number of spots, and was classified as an E-type/beta-gamma-delta magnetic configuration. It is showing some flux emergence at both the leading and trailing portions. Further C-class activity is expected over the next 24 hours. The position of NOAA 12305 on March 26 at 12:35 UT is: S08E12 (Solar X = -198", Solar Y = -22") 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 has increased over the past 24 hours. Target region, NOAA 12305, was the source of three C-class events (the largest being a C8.7 at 04:36 on March 25). 12305 increased its spot area, and was once classified as a beta-gamma-delta magnetic type, though the delta configuration has somewhat decayed now. 12305 continues to show some mixed polarities in its intermediate portion. C-class activity is expected with a slight chance for an M-class event in the next 24 hour period. The position of NOAA 12305 on March 25 at 12:35 UT is: S08E25 (Solar X = -404", Solar Y = -29") 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 low levels with numerous B-class events emanating from the visible disk. The target region NOAA 12305 continues to show signs of growth over the past 24 hours, increasing in spot area and number of spots. 12305 maintains its E-type/beta-gamma configuration and bright H-alpha plage. It is showing some flux emergence in the intermediate portion. C-class events are still possible in the next 24 hours. The position of NOAA 12305 on March 24 at 12:35 UT is: S08E37 (Solar X = -575", Solar Y = -41") 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 solar activity continues at a low level. The largest event since the last message was a C3.6 at 08:49 UT on March 23 produced by an undesignated region (S25E86) over the South East limb. Yesterday's target region NOAA 12305 has increased in spot area and count, and now is classified as an E-type/beta-gamma magnetic configuration. C-class activity is possible in the next 24 hours. The position of NOAA 12305 on March 23 at 12:35 UT is: S08E51 (Solar X = -742", Solar Y = -60") 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 region 12303, has remained flare quiet since the last message. NOAA 12305 has shown signs of growth over the previous 24 hours, increasing in spot area and number of spots. This region was first classified today as a beta/D-type sunspot group, but now appears to show mixed polarities in its intermediate portion (making 12305 a beta-gamma region classification). C-class activity is possible over the next 24 hours. The position of NOAA 12305 on 22-Mar-2015 at 22:00 UT is: S08E55, ( -781", -66" ) 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.
