MM#009 Default Target
by Max Millennium Chief Observer 11 Aug '21

11 Aug '21

MM#009 Default Target Dear Collaborators, The spotless target region NOAA 2853 is mostly unchanged. It produced only two minor A-class events in the past 24 hour period. Two tiny regions with tiny spots emerged since the last message. They are located at S22W29 and N13E67. Solar flare activity is expected to continue at a very low level for the next 24 hours. The position of NOAA 2853 on August 11 at 14:00 UT is: N25E31 (Solar X = -444", Solar Y = 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.

MM#009 Default Target Dear Collaborators, The visible solar disk is spotless. Target region NOAA 2853 decayed somewhat losing its tiny spots. In the past 24 hours 2853 was the source of minor A-class events and a single B3.0 event at 08/09/18:20 UT. B-class activity possible with only a slight chance of an isolated C-class event in the next 24 hour period . The position of NOAA 2853 on August 10 at 14:00 UT is: N25E44 (Solar X = -598", Solar Y = 330") 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 is now numbered NOAA 2853. 2853 was the source of numerous minor A- and B-class events since the last message. It also produced an isolated C1.3 event at 08/08/00:04 UT. The activity was associated with an active/eruptive filament located along the region's main magnetic inversion line and a tiny negative polarity spot that emerged yesterday within the positive polarity leading plage. There are a few tiny pores currently visible in both leading and trailing areas of the region. B-class activity likely with another C-class event possible in the next 24 hour period. The position of NOAA 2853 on August 09 at 14:00 UT is: N25E55 (Solar X = -704", Solar Y = 344") 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 current visible solar disk is spotless. The only noteworthy event since the last message was a limb occulted B5.4 at 08/07/17:01 UT produced by NOAA 2850 located well beyond the SW limb at approximately S30. The large spotless target plage was unchanged and quiescent in the past 24 hour period. Minor B-class activity is possible in the next 24 hours. The position of the target on August 08 at 14:00 UT is: N26E67 (Solar X = -785", Solar Y = 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#009 Default Target Dear Collaborators, Target region NOAA 2850 was the source of four B-class events since the last message. The largest was a B2.6 at 08/06/19:21 UT. 2850 has completed west limb passage. The target will switch to the return of old NOAA 2842 rotating over the northeastern limb. The region is currently spotless. This region produced a minor B1.6 event at 08/06/19:21 UT. Minor A- and B-class events possible in the next 24 hour period. The position of the target on August 07 at 14:00 UT is: N25E80 (Solar X = -845", Solar Y =382") 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 spotless target region NOAA 2850 was the source of a B1.4 event at 08/05/23:31 UT. There is a region located just beyond the northeastern limb at approximately N25 that will likely be the target tomorrow. Only minor events expected in the next 24 hour period. The position of NOAA 2850 on August 06 at 10:00 UT is: S30W75 (Solar X = 792", Solar Y = -493") 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 2850 has decayed significantly since the last message and is now spotless. There are two regions on the visible disk that have tiny B-type/beta sunspot groups (S12E47 and N16W03). No significant events expected anytime soon. The position of NOAA 2850 on August 05 at 15:30 UT is: S31W64 (Solar X = 729", Solar Y = - 522") 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 leading sunspot in target region NOAA 2850 has decayed significantly. The trailing sunspots of the simple B-type/beta sunspot group are mostly unchanged. 2850 produced three A- and two B-class events since the last message. The largest event was a B5.9 at 08/04/03:29 UT. A- and B-class events possible in the next 24 hour period. The position of NOAA 2850 on August 04 at 14:00 UT is: S32W50 (Solar X = 616", Solar Y = -554") 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 2850 was the source of two minor A-class events and two B-1.0 events since the last message. The region's leader sunspot area increased but the trailing spots have decayed somewhat. The region is maintaining its magnetically simple C-type/beta sunspot group. A- and B-class events possible in the next 24 hour period. The position of NOAA 2850 on August 03 at 14:00 UT is: S32W37 (Solar X =484", Solar Y = -567") 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 2846) has completed west limb passage. The new target will be the recently emerged NOAA 2850. 2850 is currently displaying a simple C-type/beta sunspot group that appears to be slowly developing. Minor A- and B-type events possible in the next 24 hours. The position of NOAA 2850 on August 02 at 14:30 UT is: S32W23 (Solar X = 314", Solar Y = -576") 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.
