MM#009 Default Target
by Max Millennium Chief Observer 28 Feb '22

28 Feb '22

Dear Collaborators, The NOAA 12954/12955 complex has remained quiescent since the last message. There has been B-level activity from an EFR in the northeast quadrant, while a pore close to NOAA 12957 in the southeast quadrant has produced two C-class flares, including a C3.1 at 09:02 UT today. NOAA 12957 and the surrounding area shall be the new target region with further B- and C-level activity possible. The position of NOAA 12957 on 28-Feb-2022 at 12:30 UT is: S13E50, ( -724", -140" ) 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 largest event since the last message was a C1.5 event at 02/27/06:26 UT. The source was a recently emerged region (S14E60). It is currently displaying a B-class/beta sunspot group with several tiny spots. Target region 2955 was mostly unchanged. The target position will slightly change to include both 2955 and 2954. No significant solar flare activity expected in the next 24 hours. The position of NOAA 2954/2955 on February 27 at 15:00 UT is: N16W05 (Solar X = 082", Solar Y =383") 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 largest event since the last message was a C5.1 at 02/25/21:40. Its source was the east limb region located at S26. The region currently appears to be a spotless decaying plage but it is still too close to the limb to ascertain if it has sunspots. It is most likely the return of old NOAA 2944. Target region NOAA 2955 is mostly unchanged. A C-class event is possible in the next 24 hour period. The position of NOAA 2955 on February 26 at 15:00 UT is: N16E13 (Solar X = -210", Solar Y = 380") 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 2955 was mostly unchanged and was mostly quiescent. STEREO-A images show two regions about to begin southeastern limb passage in the location of the return of old NOAA regions 2939 (S17) and 2944 (S26). Both regions were the source of occulted minor B-class events. The largest was a B3.1 at 02/15/11:36 UT produced by the region located at S26. No significant solar flare activity expected in the next 24 hour period. The position of NOAA 2955 on February 25 at 17:30 UT is: N15E25 (Solar X = -397", Solar Y = 356") 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 2955 developed a few more small sunspots just east of its large leader sunspot since the last message but most of them quickly decayed. 2955 was the source of six B-class events in the past 24 hours. The largest was a B9.3 at 02/24/02:54 UT. A C-class event is possible in the next 24 hour period. The position of NOAA 2955 on February 24 at 15:00 UT is: N16E40 (Solar X = -601", Solar Y = 355") 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 2955 developed a few spots located within its leading polarity just east of the large leader sunspot. 2955 was the source of seven minor B-class events since the last message. The largest was a B4.9 at 02/23/02:44 UT. A C-class event is possible in the next 24 hour period. The position of NOAA 2955 on February 23 at 15:00 UT is: N16E53 (Solar X = -746", Solar Y = 336") 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 2955 has completed east limb passage. 2955 is currently displaying a magnetically simple H-type/alpha sunspot group. 2955 was the source of several minor B-class events and two C-class events. The largest was a C3.2 at 02/21/19:00 UT. C-class events are possible in the next 24 hour period. The position of NOAA 2955 on February 22 at 15:00 UT is: N16E66 (Solar X = -853", Solar Y = 313") 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's large leading sunspot is now visible near the northeastern limb. The intermediate and trailing sunspots are still beyond the limb. There were no noteworthy events in the past 24 hours. It appears that the region has decayed after the large flare event and CME on February 15-16. C-class events are still very possible with a chance of an isolated M-class event in the next 24 hours. The position of the target region on February 21 at 15:00 UT is: N15E78 (Solar X = -917", Solar Y = 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.

MM#009 Default Target Dear Collaborators, The target region located beyond the northeastern limb was the source of minor B-class activity and two C-class events in the past 24 hours. The largest event was a limb occulted C5.2 at 02/20/04:07 UT. C-class events expected with the chance of an isolated M-class event in the next 24 hour period. The position of the target on February 20 at 15:00 UT is: N18E87 (Solar X= -922", Solar Y = 304") 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 2948 (S28W08) is mostly unchanged and quiescent in the past 24 hours. The target will switch to a region located just beyond the northeastern limb that was the likely source of the very large CME on February 17th. The region produced three limb occulted B-class events today. The largest event was a B4.7 at 02/19/17:12 UT. C-class activity probable with the chance of an isolated M-class event in the next 24 hour period. The position of the target on February 19 at 13:00 UT is: N17E87 (Solar X = -927", Solar Y = 288") 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.
