MM#009 Default Target Dear Collaborators, Target region NOAA 2916 (E-type/beta-gamma) is decaying and produced only a couple of minor B-class events in the past 24 hours. The largest event since the last message was a C9.8 at 12/31/06:56. The source region was almost spotless NOAA 2918 (N20W63). A C-class event is possible in the next 24 hour period. The position of NOAA 2916 on December 31 at 15:45 UT is: S17W44 (Solar X = 650", Solar Y = -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.

MM#009 Default Target Dear Collaborators, NOAA regions 2915, 2918, and 2921 produced several minor B-class events in the past 24 hours. The target region NOAA 2916 (E-type/beta-gamma) added a few small leading polarity sunspots located just east of the large trailing polarity sunspot since the last message. Those spots are now decaying. C-class events possible with only a very slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2916 on December 30 at 15:00 UT is: S17W30 (Solar X = 468", Solar Y = -246") 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 Target Dear Collaborators, Target region NOAA 2918 (N20W36) has decayed and produced only a few B-class events since the last message. The target will switch back to NOAA 2916. 2916 has decayed slightly but remains the largest region on the visible disk with its E-type/beta sunspot group. 2916 was the source of a C4.6 event at 12/29/04:28. Another C-class event likely with a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2916 on December 29 at 15:00 UT is: S17W17 (Solar X = 274", Solar Y = -244") 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 Target Dear Collaborators, The Target region NOAA 2916 (S17W04, E-type/beta) is mostly unchanged and was quiescent in the past 24 hours. The target will switch to NOAA 2918 for the next 24 hour period. 2918 was the source of several C-class events and an M1.8 event at 12/28/04:01 UT. The events were centered on the location of recently emerged opposite polarity flux within the region's leading polarity portion. The magnetic class of the region's sunspot group is now beta-gamma. C-class events likely with the chance of another M-class event in the next 24 hours. The position of NOAA 2918 on December 28 at 15:00 UT is: N21W23 (Solar X = 357", Solar Y = 389") 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 Target Dear Collaborators, Several minor C-class events were produced by NOAA regions 2908, 2915, 2916, 2917, and 2920. NOAA 2908 located beyond the southwestern limb was the source of the largest event (C3.2 at 12/26/20:12 UT). Target region NOAA 2916 is not as magnetically complex today losing its beta-gamma-delta configuration but it still has a large E-type/beta sunspot group with some weak mixed polarities within its trailing portion. C-class events are possible from several regions currently located on the visible solar disk. Target region NOAA 2916 has the potential to produce C-class events with a slight chance an isolated M-class event in the next 24 hour period. The position of NOAA 2916 on December 27 at 15:00 UT is: S17E09 (Solar X = -147", Solar Y = -246") 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 Collaborators, Solar activity has remained at moderate levels with NOAA 12918 in the northern hemisphere producing a series of low C-class flares. However, the target region NOAA 12916 has continued to develop and is now classified as a beta-gamma-delta/E-type region with an area of almost 500uh. The delta spot is at the trailing edge of the region. Despite remaining quiescent, the region may become more active over the next 24 hours with chance of an M-class flare. The position of NOAA 12916 on 26-Dec-2021 at 12:30 UT is: S18E21, ( -333", -266" ) 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 Collaborators, Solar activity has dropped to the C1 level since the last message with flares from multiple regions. NOAA 12907 and 12908 have continued to decay as they transit the western limb. Meanwhile, NOAA 12916 has increased in size and shows signs of mixed polarities in its trailing region. NOAA 12916 shall be the new target region with C-level activity possible over the next 24 hours. The position of NOAA 12916 on 25-Dec-2021 at 08:30 UT is: S18E37, ( -560", -273" ) 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 Collaborators, Solar activity continues at intermediate levels with NOAA 12907 and 12908 continuing to produce C-class flares. The largest event since the last message was a C7.4 flare from NOAA 12917 at 03:25 UT. NOAA 12907 retains its beta-gamma configuration while NOAA 12908 has reverted back to a beta region as they both approach the southwest limb. NOAA 12908 shall remain the target region but also include NOAA 12907 in your field of view if possible. Further C-level activity likely. The position of NOAA 12908 on 24-Dec-2021 at 12:30 UT is: S20W59, ( 787", -316" ) 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 Collaborators, Solar activity has diminished since the last message. There have been a number of low C-class flares from the multi-region complex in the southwest quadrant. NOAA 12908 has now been classified as a beta-gamma region along with NOAA 12907 as they merge together. Further C-level activity expected over the next 24 hours with chance for an additional isolated M-class flare. The position of NOAA 12908 on 23-Dec-2021 at 12:30 UT is: S20W46, ( 661", -312" ) 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 Collaborators, Solar activity remains elevated with twelve numbered active regions now present on the visible solar disk. NOAA 12908 remains unchanged in terms of size and complexity and continues to produce C-level activity as well as an M1.3 flare at 06:54 UT today. The new region now on the southeast limb has now been designated as NOAA 12916 and has also produced two M1 flares since the last message. NOAA 12908 shall remain the target region with further intermediate level activity expected. Also include NOAA 12907 and 12909 in your field of view if possible. The position of NOAA 12908 on 22-Dec-2021 at 16:30 UT is: S20W35, ( 527", -309" ) 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.
