MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 2659 produced minor B-class events since the last message. The largest was a B6.8 event at 05/30/19:47 UT. 2659 is now well beyond the west limb. The new target is a region located on the northeastern limb where small leader sunspots are visible. The region was the source of limb occulted B-class events today. The largest was a B6.4 at 05/31/11:40 UT. Additional B-class activity possible with a slight chance of an isolated C-class event in the next 24 hour period. The very large quiescent filament located in the southeastern quadrant at approximately S14E28 disappeared centered around 05/30/12:00 UT. The position of the target on May 31 at 06:30 UT is: N05E89 (Solar X = -943", Solar Y = 083") 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 visible solar disk is currently spotless. NOAA 2659 has completed west limb passage but is displaying some weak limb surges. 2659 was the source of minor B-class activity since the last message. No significant solar flare events expected in the next 24 hour period. The position of NOAA 2659 on May 30 at 13:30 UT is: N13W91 (Solar X = 921", Solar Y = 212") 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 2659 was the source of a C3.3 event at 05/28/19:28 UT and a C1.0 event at 05/28/23:13 UT. 2659 developed some minor mixed polarities in its trailing portion yesterday but has decayed since the C-class activity. 2659 is currently displaying a D-type/beta sunspot group. B-class activity and another isolated C-class event is possible before 2659 completes west limb passage. The position of NOAA 2659 on May 29 at 15:30 UT is: N13W79 (Solar X = 905", Solar Y = 215") 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 12659 has produced numerous B-class flares since the last message including a B9.2 flare at 17:47 UT yesterday. The region is approaching the western limb and is continuing to develop. It shall remain the target region with further B- and C-level activity possible. The position of NOAA 12659 on 28-May-2017 at 13:30 UT is: N13W65, ( 837", 220" ) 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 the B-level. The target region NOAA 12659 has developed into beta-gamma region with a large leader spot as it approaches the western limb. Further B-level activity expected with chance for an isolated C-class flare. The position of NOAA 12659 on 27-May-2017 at 11:30 UT is: N14W52, ( 725", 241" ) 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. Target region NOAA 12659 produced a few low B-class flares since the last message. 12659 was reclassified as a beta/D-type region, increasing in sunspot area and number of spots. It shows some mixed polarities in its intermediate portion, and shall remain the target region for another 24 hours. B-class activities are expected with a slight chance of an isolated low C-class event. The position of NOAA 12659 on May 26 at 11:30 UT is: N13W39 (582", 230") 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 12660 was the source of another B-class flare since the last message (a B3.8 flare at 13:31 UT yesterday). NOAA 12659 continues to develop but has remained quiescent. A new active region appears to be rotating on to the eastern limb, but NOAA 12659 shall remain the target region for a further 24 hours. Slight chance of an isolated low level event. The position of NOAA 12659 on 25-May-2017 at 11:30 UT is: N12W25, ( 392", 218" ) 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 since the last message was a B4.4 flare from NOAA 12660 at 14:04 UT yesterday. NOAA 12659 is undergoing renewed flux emergence in its trailing portion and shall remain the target region. Chance for some additional low level activity over the next 24 hours. The position of NOAA 12659 on 24-May-2017 at 07:30 UT is: N13W10, ( 160", 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.

Dear RHESSI Collaborators, Solar activity continues at very low levels. NOAA 12659 has remained quiescent and its trailing spot has almost completely decayed. It shall remain the target region as it crosses the central meridian, although no increase in activity is expected at this time. The position of NOAA 12659 on 23-May-2017 at 13:30 UT is: N14E03, ( -48", 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, Solar X-ray flux remains steady at the sub-B-level. The newly emerged region in the northeast quadrant has now been designated as NOAA 12659, and is classified as a beta/D-type region. It shall continue to be the target region although no significant increase in activity is expected at this time. The position of NOAA 12659 on 22-May-2017 at 07:30 UT is: N14E22, ( -345", 257" ) 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.
