MM#003 Major Flare Watch
by Max Millennium Chief Observer 31 Jan '22

31 Jan '22

Dear Collaborators, The level of solar activity is moderate. The target region NOAA 12936 has shown some evolution over the past 24 hours, now being classified as a beta/E-type sunspot group. This region contains some intermediate pores, several of which have consolidated into the primary leading and trailing sunspots. NOAA 12396 has continued producing C-class activity since the last message (6 in total, but all low C-class). Additional C-class activity is expected over the following 24-hour period, while the Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare) will remain in effect as NOAA 12936 retains the potential to produce a >M5 flare. The position of NOAA 12936 on 31-Jan-2022 at 16:00 UT is: N17W18 , ( 285", 377" ) 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

MM#003 Major Flare Watch Dear Collaborators, At this time we are implementing Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare). Target region NOAA 2936 has developed a weak magnetic delta in the trailing portion of its E-type/beta-gamma-delta sunspot group. 2936 produced an isolated M1.1 event and several C-class events since the last message. The M1.1 was at 01/29/23:32 UT. Another low level M-class event is likely with an event >M4 possible. There is only a slight chance of an X-class event in the next 24 hours. The position of NOAA 2936 on January 30 at 15:00 UT is: N17W04 (Solar X = 065", Solar Y = 381") 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

29 Jan '22

MM#009 Default Target Dear Collaborators, Target region NOAA 2936 continues to increase its sunspot area and spot count. 2936 has a large compact E-type/beta sunspot group with a mostly E-W magnetic inversion line with leading and trailing polarities closely spaced. Continued growth might result in the region forming a magnetic delta configuration. 2936 produced several C-class events since the last message. The largest was a C6.9 at 01/29/12:19 UT. A region beyond the southeastern limb at approximately S16 was the source of a limb occulted C7.3 event at 01/29/16:55 UT. C-class events certain with an excellent chance of an isolated low level M-class event. A larger M-class (>M3) is possible if a magnetic delta configuration develops in the next 24 hour period. The position of NOAA 2936 on January 29 at 15:45 UT is: N17E10 (Solar X = -162", Solar Y = 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.

MM#009 Default Target Dear Collaborators, Target region NOAA 2936 developed significantly in the past 24 hour period. New flux emergence within the leading and intermediate portion has increased sunspot area and spot count. Should growth continue the region may develop a magnetic delta configuration. 2936 was the source of eight minor C-class events since the last message. The largest was a C3.1 at 01/28/17:35 UT. C-class events expected and if the region continues in growth phase, there is a good chance of an isolated M-class event in the next 24 hours. The position of NOAA 2936 on January 28 at 15:45 UT is: N17E24 (Solar X = -380", Solar Y = 370") 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 2938 (N18E63, B-type/beta) produced numerous B-class events and a C1.4 event at 01/27/12:26 UT. 2938 has decayed somewhat losing penumbral area. The target will switch back to NOAA 2936. 2936 has slightly increased its sunspot area and spot count but its sunspot group remains a D-type/beta. If possible, include 2938 within your FOV. Another C-class event likely with a slight chance of an isolated M-class event in the next 24 hours. The position of NOAA 2936 on January 27 at 15:45 UT is: N17E37 (Solar X = -563", Solar Y = 358") 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 2936 (N16E53, D-type/beta) is mostly unchanged and was the source of only minor B-class activity since the last message. We will switch to a new region located just east of 2936. The new target produced a few C-class events including a C9.9 event at 01/25/23:49 and a C7.2 event at 01/26/07:32 UT. The region is currently displaying a small C-type/beta sunspot group with some mixed polarities. If possible, include 2936 within your FOV. C-class activity likely with an isolated M-class event possible in the next 24 hours. The position of the target on January 26 at 15:00 UT is: N18E76 (Solar X = -900", Solar Y =322") 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, Newly assigned target region NOAA 2936 was the source of a dozen B-class events and three C-class events since the last message. The largest was a C3.7 at 01/25/10:29 UT. 2936 is currently displaying a D-type/beta sunspot group. B-class events expected with C-class events likely in the next 24 hour period. The position of NOAA 2936 on January 25 at 15:00 UT is: N16E66 (Solar X = -857", Solar Y = 305") 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

24 Jan '22

MM#009 Default Target Dear Collaborators, Target region NOAA 2934 (S25E18) has been quiescent since the last message. The target will switch to a new region located on the northeastern limb. This region was the source of a few B-class and two C-class events today. The largest event was a C1.1 at 01/24/02:37 UT. The region's sunspot group is too close to the limb to ascertain its magnetic configuration. B-class events likely with C-class events possible in the next 24 hours. The position of the target region on January 24 at 15:00 UT is: N15E80 (Solar X = -928", Solar Y = 267") 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 to be at a very low level. The largest event since the last message was a B6.4 flare at 01/22/06:55 UT produced by NOAA 12930 which has completely rotated over the west limb now. At present there are two regions with sunspots on the visible solar disk, NOAA 12933 and 12934, both of which have an alpha/H-type configuration. 12933 (S19W80) is rotating over the west limb. The target will be 12934 today. Only low activities are possible in the next 24 hours. The position of NOAA 12934 on January 23 at 08:30 UT is: S25E36 (-520", -345") 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 been at a very low level. Only a few B-class flares were produced by the target region NOAA 12929 (the largest one being a B5.5 at 01/21/08:07 UT). 12929 has rotated beyond the west limb with some overlying loops visible. Today we will watch this region for a final 24 hours. B-class activities are expected in the next 24 hours. The approximate position of NOAA 12929 on January 22 at 04:30 UT is: N08W91 (964", 133") 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.
