MM#009 Default Target
by Max Millennium Chief Observer 18 Feb '22

18 Feb '22

MM#009 Default Target Dear Collaborators, Target region NOAA 2941, now located well beyond the northwestern limb, was the source of a B8.9 event at 02/17/22:07 UT. The target will switch to NOAA 2948 (C-type/beta). No significant solar flare activity expected in the next 24 hour period. The position of NOAA 2948 on February 18 at 15:00 UT is: S27E07 (Solar X = -106", Solar Y = -335") 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 2941 was the source of three limb occulted C-class events. The largest was a C2.3 at 02/17/06:02 UT. All three C-class events were associated with limb flare sprays. The largest spray appeared with the C1.0 event at 02/17/03:24 UT. 2941 is located beyond the northwestern limb but there is a slight chance of another C-class event in the next 24 hour period. The position of NOAA 2941 on February 17 at 16:30 UT is: N25W91 (Solar X = 879", Solar Y = 405") 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 2941 continues to slowly decay and produced only minor B-class events since the last message. C-class activity possible with a slight chance of an isolated M-class event before 2941 completes west limb passage. The position of NOAA 2941 on February 16 at 12:30 UT is: N24W86 (Solar X = 884", Solar Y = 399") 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 2941 produced an isolated M1.3 event at 02/15/18:15 UT. 2941 has decayed somewhat in the past 24 hours but it is maintaining its E-type/beta-gamma sunspot group. Another M-class event is possible before 2941 rotates beyond the northwestern limb. An EFR located S22W33 was the source of two C-class events. The largest was a C4.7 at 02/15/05:18 UT. The EFR is currently displaying a C-type/beta-gamma sunspot group. The position of NOAA 2941 on February 15 at 15:00 UT is: N25W73 (Solar X = 843", Solar Y = 439") 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 2939 is now located beyond the southwestern limb at S22. The target will switch to NOAA 2941. 2941 has new leading polarity flux emerging within the trailing polarity of its F-type/beta-gamma sunspot group. 2941 produced five C-class events and was the source of an isolated M1.0 event at 02/14/17:31 UT. The emerging flux might form a magnetic delta configuration if growth continues. C-class events expected and another M-class event is very possible in the next 24 hours. The position of NOAA 2941 on February 14 at 15:00 UT is: N25W60 (Solar X = 764", Solar Y = 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, There were two high C-class flares from the western limb since the last message: a C9.2 flare from NOAA 12940 in the north and a C8.0 from the NOAA 12939/12944 complex in the south. The sunspots of NOAA 12939 are now beyond the western limb but the looptops shall remain the target for a further 24 hours. Isolated C-class flare possible before west limb passage. The position of NOAA 12939 on 13-Feb-2022 at 08:30 UT is: S22W88, ( 900", -366" ) 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, NOAA 12939 near the southwest limb was the source of an M1.4 flare at 08:25 UT, as well as some low C-class activity. NOAA 12941 has remained quiescent since the last message and has shown signs of decay. Although the magnetic configuration of NOAA 12939 is unclear at this time, it shall be the new target region for the next 24 hours. Further C-level activity likely, with chance for another low M-flare before west limb passage. The position of NOAA 12939 on 12-Feb-2022 at 12:30 UT is: S16W91, ( 933", -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 has returned to low levels. There have been ~C1 events from multiple regions across the disk since the last message, including NOAA 12941. The region remains unchanged in terms of size and complexity and shall continue as the target region. Only isolated low-level events expected at this time. The position of NOAA 12941 on 11-Feb-2022 at 12:30 UT is: N24W22, ( 333", 489" ) 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 increased to C-level since the last message with several events emanating from NOAA 12941. However, the largest event of the past 24 hours was a C5.7 flare from NOAA 12939. NOAA 12941 has continued to increase in size but has decreased in complexity as it has reverted back to a beta class region. It shall continue as the target region with further B- and C-level activity possible. The position of NOAA 12941 on 10-Feb-2022 at 12:30 UT is: N24W12, ( 185", 494" ) 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 low levels. The largest event since the last message was a C5.1 flare from NOAA 12939 in the southwest quadrant at 21:29 UT yesterday, while the target region NOAA 12941 has continued to produce B-level activity. NOAA 12941 has continued to develop and is now classified as a beta-gamma region as it crosses the central meridian. Further B-level activity expected with chance for some C-class flares over the next 24 hours. The position of NOAA 12941 on 9-Feb-2022 at 12:30 UT is: N23E03, ( -47", 481" ) 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.
