MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Apr '14

30 Apr '14

Dear RHESSI Collaborators, NOAA 12048 has remained quiescent over the past 24 hours on its approach to the western limb and has begun to show signs of decay. NOAA 12049, a large beta-gamma region in the southeast quadrant, was the source of two C1 flares since the last message and shall be the new target region. NOAA 12049 appears to be increasing in both size and complexity and is likely to produce further C-level events. The position of NOAA 12049 on 30-Apr-2014 at 11:00 UT is: S07E36, ( -557", -59" ) 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. The target region, NOAA 12048, was the source of several B-class flares since the last message, as well as a C3.4 flare at 15:17 UT yesterday. The region maintains its beta configuration and has shown signs of flux emergence in its leader spot. Further low-level activity likely with chance for an additional isolated C-class flare. The position of NOAA 12048 on 29-Apr-2014 at 07:35 UT is: N20W55, ( 734", 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 continues at low levels. The newly-emerged region in the northwest quadrant has now been designated as NOAA 12048, and was the source of a B7.3 flare at 04:07 UT today. The region continues to show signs of development and maintains its mixed polarity core. Further low-level events likely with a chance for C-class activity. The position of NOAA 12048 on 28-Apr-2014 at 07:35 UT is: N20W41, ( 589", 378" ) 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 current level of solar activity is low. Since the previous message, yesterday's target region (NOAA 12047) has not produced significant activity, and its flux emergence appears to have subsided. A new AR has emerged near N20W30, exhibiting a mixed polarity (gamma-like) configuration, and also shows evidence for the formation of a mixed polarity spot in its intermediate portion. C-class activity is likely, with a chance for a high C-class flare. The position of the new region on 26-Apr-2014 at 15:40 UT is: N20W41, ( 594", 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.

Dear RHESSI Collaborators, The current level of solar activity is very low. Since the previous message, yesterday's target region (NOAA 12045) produced low C-class activity, but has since decayed. A small bipole has since emerged near the East limb. Low C-class activity is possible. The position of the new region on 26-Apr-2014 at 15:40 UT is: S17W72, ( 866", -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.

Dear RHESSI Collaborators, The current level of solar activity is low. Since the previous message, yesterday's target region (NOAA 12046) has progressed over the West limb. The Major Flare Watch (MFW) is ended at this time. There is evidence for minor flux emergence adjacent (just East) to the large spot in NOAA 12045. Low C-class activity is possible. The position of 12045 on 25-Apr-2014 at 18:10 UT is: S25W01, ( 012", -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#003 Major Flare Watch
by Max Millennium Chief Observer 24 Apr '14

24 Apr '14

Dear RHESSI Collaborators, The current level of solar activity is high. Since the previous message, an X1.3 flare has occurred on 25-Apr-2014 at 00:17 UT at the limb, likely within yesterday's target region (NOAA 12035), which is located beyond the West limb. The flare was likely connected to today's target region (newly numbered NOAA 12046). Therefore, the target will remain with NOAA 12046. If possible, the instrument should include the area at the West limb, just to the North- West of 12046 within its FOV. A Major Flare Watch (MFW) is now in effect. A further significant flare (>M5) is possible. The position of 12046 on 25-Apr-2014 at 01:10 UT is: S17W79, ( 895", -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, The current level of solar activity is low. Since the previous message, yesterday's target (NOAA 12035) was responsible for C-class activity, but has now rotated over the West limb. A new bipolar region has emerged 10-20 degrees east of 12035. So far it has been connected to at least one C-class event rooted in 12035. Further low C-class activity is expected. The position of the new region on 24-Apr-2014 at 17:20 UT is: S17W73, ( 875", -256" ) 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 current level of solar activity is low-moderate. Since the previous message, yesterday's target (NOAA 12035) was responsible for C-class activity, including the largest since the previous message, a C5.1 flare on 23-Apr-2014 at 12:48 UT. Flux emergence within the region appears to have subsided. Further moderate C-class activity is possible, with a chance for a high C-class flare. The position of NOAA 12035 on 23-Apr-2014 at 17:40 UT is: S13W81, ( 918", -201" ) 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 current level of solar activity is low-moderate. Since the previous message, yesterday's target (NOAA 12035) was responsible for a series of C-class events, including the largest event since the previous message, a C8.8 flare on 22-Apr-2014 at 11:29 UT. The region is undergoing continued flux emergence and exhibits at least one small mixed-polarity spot. Further high C-class activity is possible, with a chance for a low M-class flare. The position of NOAA 12035 on 22-Apr-2014 at 17:20 UT is: S15W68, ( 853", -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.
