MM#009 Default Target

Dear Collaborators, The level of solar activity is very low. Target region NOAA 12965 has now fully rotated over the North West limb. The plage region that was previously designated as NOAA 12971 has undergone some flux emergence and is consolidating flux into two small opposite-polarity spots, and was the source of mid-B-class flares since the last message. The most flare-productive region is a new spot region rotating over the South East limb that has produced several footpoint occulted B-class flares as well as the largest flare of the period (a C1.2 on 20-Mar-2022 at 18:04 UT). Further B-class activity is expected, with a good chance for mid-/high- C-class activity over the following 24-hour period. The approximate position of this region on 21-Mar-2022 at 18:00 UT is: S18E90 , ( -916", -295" ) 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 in the past 24 hours was a C4.6 at 03/20/07:30 UT produced by NOAA 12971 that just re-emerged some tiny spots. Target region NOAA 12965 has decayed to a beta/C-type configuration and is rotating beyond the west limb. It was the source of a C2.1 flare and also a few B-class flares. Additional C-class activities are probably in the next 24 hours. The position of NOAA 12965 on March 20 at 08:30 UT is: N26W73 (828", 450") 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 at a very low level. The largest event in the past 24 hours was a C1.3 flare at 03/19/03:49 UT produced by target region NOAA 12965. 12965 also produced seven B-class flares during the period. It retains a beta/F-type configuration but decays further. Additional C-class activities are expected with a slight chance of a low M-class flare when 12965 rotates over the west limb. The position of NOAA 12965 on March 19 at 08:30 UT is: N25W60 (757", 458") 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 since the last message. Target region NOAA 12965 was the source of a C1.0 (at 03/17/19:06 UT, being the largest event) and two high B-class flares in the past 24 hours. 12965 has decayed to a beta/F-type region, significantly decreasing in the number of spots. Additional C-class activities are expected with a light chance of a low M-class flare in the next few days. The position of NOAA 12965 on March 18 at 08:30 UT is: N24W49 (666", 461") 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 low level since the last message. The largest event of the period was a C1.2 at 03/17/01:36 UT produced by the target region NOAA 12965. 12965 also produced several B-class flares. It retains a beta-gamma/F-type configuration but appears to enter the decay phase. Further C-class activities are expected still with a chance of a low M-class flare in the next few days. The position of NOAA 12965 on March 17 at 08:30 UT is: N24W35 (506",480") 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 moderate level. The target region NOAA 12965 was the source of two low M-class flares (an M1.4 at 03/15/12:33 UT and an M1.5 at 03/15/22:39 UT), five C-class flares, and also five B-class flares. 12965 retains a beta-gamma/F-type configuration while decreasing in the sunspot area. It continues showing mixed polarities in both of its leading and trailing portions. Further low M-class flares are likely and More C-class flares are expected in the next few days. The position of NOAA 12965 on March 16 at 16:30 UT is: N24W27 (401",488") 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 moderate level since the last message. The largest event of the period was an M2.0 at 03/14/08:29 UT produced by the target region NOAA 12965. 12965 also produced six C-class flares. This region was re-classified as a beta-gamma/ F-type configuration. More C-class activities are expected with a chance of additional low M-class flare in the following 24 hours. The position of NOAA 12965 on March 15 at 04:30 UT is: N24W06 (92",500") 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 low level. The largest event since the last message was a C3.9 flare at 03/13/23:24 UT produced by the region NOAA 12966 that has rotated over the west limb. The target region NOAA 12965 produced a C1.3 and a C2.1 flare just today. It shows signals of decay and has been classified as a beta/F-type region. Further C-class activities are expected in the next 24 hours. The position of NOAA 12965 on March 14 at 04:30 UT is: N24E06 (-92", 500") 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 is at a low level. Target region NOAA 12964 has now rotated over the South West limb, producing a foot-point occulted B8.7 flare on 13-Mar-2022 at 09:54 UT. The only region to produce C-class flares since the last message was spotless NOAA 12962 (the largest being a C4.9 flare on 13-Mar-2022 at 03:12 UT). The target returns to NOAA 12965, which has shown signs of redistribution and flux emergence to now be classified as a beta-gamma/F-type sunspot group. C-class flares are possible in the following 24-hour period. The position of NOAA 12965 on 13-Mar-2022 at 20:00 UT is: N23E11 , ( -173", 485" ) 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, The level of solar activity is moderate. Target region NOAA 12965 has grown slightly since the last message, but it remains classified as a beta/E-type sunspot group. NOAA 12965 produced several C-class flares, while decaying NOAA 12964 also produced several C-class flares and the largest flare of the period - an M2.2 on 12-Mar-2022 at 22:13 UT. NOAA 12964 is currently approaching the South West limb, but it becomes the target region for the next 24 hours. More C-class activity is expected over the next 24 hours, with a small chance for another M-class flare. The position of NOAA 12964 on 12-Mar-2022 at 22:30 UT is: S28W80 , ( 840", -431" ) 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.
