MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Dec '16

31 Dec '16

Dear RHESSI Collaborators, Solar activity is at very low levels. A new region has been designated as NOAA 12622. It is currently the only region with sunspots on the visible solar disk. Today the target will switch to 12622 with an Alpha/A-type sunspot group. No notable events are expected in the following 24 hours. The position of NOAA 12622 on December 31 at 14:30 UT is: N12W68 (885", 221") 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 visible solar disk is spotless again. The target region NOAA 12621 has rotated beyond the west limb with some overlying loops still visible. 12621 produced several minor B-class events in the past 24 hours. We will watch this region for a further 24 hours. No significant activities are expected in the next 24 hours. The position of NOAA 12621 on December 30 at 20:30 UT is: N10W91 (960", 168") 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. The visible solar disk is almost spotless as the target region NOAA 12621 rotates up to the west limb. 12621 has entered the decay phase and has been downgraded to a beta/B-type region. Only minor activities are possible in the next 24 hours. The position of NOAA 12621 on December 29 at 14:30 UT is: N10W83 (953", 174") 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 been extremely low with the GOES soft X-ray flux flat at ~A8 level. The target region NOAA 12621 has been flare quiet since the last message. 12621 now has a beta/C-type sunspot group, increasing in sunspot area and number of spots slightly. B-class activities are likely in the next 24 hour period. The position of NOAA 12621 on December 28 at 14:30 UT is: N10W70 (903", 184") 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 slightly. The target region, designated as NOAA 12621, was the source of numerous B-class events with the largest one being a B8.3 at 20:56 UT yesterday. 12621 has a beta/B-type sunspot group. It is displaying mixed polarities in the leading portion. Further B-class activities are possible in the following 24 hours. The position of NOAA 12621 on December 27 at 14:30 UT is: N11W54 (776", 211") 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 visible solar disk remains spotless. Yesterday's target region NOAA 12620 has been quiescent since the last message. Today the target will switch to a newly emerged region in the northwest quadrant. This region is displaying some surges in H-alpha images. B-class activities are very likely in the next 24 hours. The approximate position of the target on December 26 at 14:30 UT is: N10W40 (580", 200") 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 visible solar hemisphere is now spotless. Solar X-ray flux remains constant below the B-level. The looptops of NOAA 12620 are still visible above the southwestern limb and shall remain the target region for a further 24 hours. No increase in activity is expected. The position of NOAA 12620 on 25-Dec-2016 at 14:30 UT is: S23W86, ( 895", -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, Solar X-ray flux remains below the B-level. NOAA 12620 is now on the western limb and has remained quiescent. It shall remain the target region for a further 24 hours although no change in activity is expected before it transits the western limb. The position of NOAA 12620 on 24-Dec-2016 at 14:30 UT is: S23W86, ( 895", -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, Quiet-Sun conditions continue. The target region NOAA 12620 has continued to decay as it approaches the western limb. The region has been downgraded to an alpha spot and is unlikely to produce any further activity before west limb passage. The position of NOAA 12620 on 22-Dec-2016 at 20:30 UT is: S23W62, ( 794", -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.

Dear RHESSI Collaborators, Solar activity continues at extremely low levels. NOAA 12620 has remained quiescent since the last message and has begun to show signs of decay. It shall remain the target region as it approaches the western limb although no significant increase in activity is expected at this time. The position of NOAA 12620 on 22-Dec-2016 at 14:30 UT is: S23W58, ( 762", -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.
