MM#009 Default Target

MM#009 Default Target Dear Collaborators, Target region NOAA 2900 continues to decay especially within its intermediate portion of its D-type/beta sunspot group. 2900 was the source of three minor B-class events in the past 24 hour period. The largest was a B3.0 at 11/30/00:20 UT. Additional B-class events possible with only a slight chance of an isolated C-class event in the next 24 hour period. The position of NOAA 2900 on November 30 at 15:00 UT is: S27W57 (Solar X = 729", Solar Y = -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.

MM#009 Default Target Dear Collaborators, Target region NOAA 2900 (C-type/beta) is now in the decay stage. 2900 produced three B-class events since the last message. The largest was a B5.2 at 11/28/18:26 UT. NOAA 2899 now located beyond the southwestern limb at S22 was the source of six limb occulted B-class events. The largest was a B4.6 at 11/29/13:11 UT. NOAA 2898 (S24W29) is decaying and has been quiescent since the last message. A- and B-class events expected with a slight chance of an isolated C-class event in the next 24 hours. The position of NOAA 2900 on November 29 at 16:30 UT is: S26W46 (Solar X = 630", Solar Y = -438") 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 2900 continued in growth phase adding sunspot area especially within its trailing portion. The region's D-type/beta sunspot group has some weak mixed polarity. 2900 was the source of six B-class events since the last message. The largest was a B8.4 at 11/28/08:59 UT. NOAA 2898 (24W16) is now decaying within its intermediate and trailing areas. A- and B-class events expected with the chance of an isolated C-class event in the next 24 hour period. Include NOAA 2898, if possible, within your FOV. The position of NOAA 2900 on November 28 at 16:30 UT is: S27W33 (Solar X = 473", Solar Y = -457") 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 EFR (NOAA 2900, C-type/beta) was the source of five B-class events since the last message. The largest was a B5.1 at 11/27/04:50 UT. NOAA 2898 (S24W04) produced two B2.4 events. 2900 added sunspot area and sunspot count in the past 24 hour period. A- and B-class events expected with the chance of an isolated C-class event in the next 24 hour period. Include 2898, if possible, within your FOV. The position of NOAA 2900 on November 27 at 15:00 UT is: S28W18 (Solar X =266", Solar Y =-433") 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, NOAA 2898 (S24E10) regained penumbral area within its trailing area but only produced one A-class event since the last message. The target will switch for at least today to a rapidly developing EFR located about 15 degrees west of 2898. The EFR was the source of numerous A- and B-class events in the past 24 hours. The largest event was a B5.0 at 11/26/10:50 UT. The EFR is displaying bright H-alpha plage and dark arch-type filaments. Include, if possible, NOAA 2898 within your FOV. A- and B-class events expected with the chance of a C-class event if the EFR continues to develop in the next 24 hour period. The position of the target on November 26 at 15:00 UT is: S28W05 (Solar X = 075", Solar Y = -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.

MM#009 Default Target Dear Collaborators, Target region NOAA 2898 was the source of numerous minor events since the last message. The largest was a B1.3 event at 11/25/03:42 UT. The region's sunspot group lost some penumbral area in its trailing sunspots. The sunspot group classification is now C-class/beta. Additional A- and B-class events expected with an isolated C-class event possible in the next 24 hour period. The position of NOAA 2898 on November 25 at 15:45 UT is: S24E24 (Solar X = -363", Solar Y = -419") 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, Solar flare activity remains at a very low level. The recently emerged target region NOAA 2898 was the source of a few minor events since the last message. The largest was a B1.3 at 11/24/16:29 UT. 2898 continues in the growth phase adding sunspot area and spot count. The region's sunspot group classification is now D-type/beta. Additional minor A- and B-class events expected with a C-class event possible in the next 24 hour period. The position of NOAA 2898 on November 24 at 15:45 UT is: S24E37 (Solar X = -536", Solar Y = -417") 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, Solar flare activity continues at a very low level. The target region (old NOAA 2891) has completed east limb passage. It is a large spotless plage. The default target will switch to an EFR that is currently displaying a small B-type/beta sunspot group. No significant solar flare events expected in the next 24 hour period. The position of the target on November 23 at 15:30 UT is: S23E52 (Solar X = -707", Solar Y = - 398") 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, Solar flare activity continues at an extremely low level. Target region NOAA 2897 is mostly unchanged and quiescent since the last message. It is maintaining its magnetically simple H-type/alpha sunspot group. The return of old NOAA 2891 is located just beyond the northeastern limb at approximately N20 degrees. 2891 was somewhat active during its previous disk passage but it currently appears to be stable. We will switch the default target to old NOAA 2891 today. Only minor events expected in the next 24 hours. The approximate position of the target on Nov. 22 at 15:00 UT is: N20E89 (Solar X = -913", Solar Y = 332") 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 quiet condition with the soft X-ray flux flat at ~A3 since the last message. At present there are two regions with sunspots (NOAA 12896 and 12897) on the visible solar disk, both of which have an Alpha/H-type magnetic configuration. The target region NOAA 12897 continues to decay and no notable events are expected in the next 24 hours. The position of NOAA 12897 on November 21 at 04:30 UT is: N17E01 (-16", 250") 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.
