MM#009 Default Target

Dear Collaborators, Solar activity continues at an extremely low level with the visible solar disk remaining spotless. The target plage region NOAA 12800 has been flare quiet since the last message. 12800 decays further as rotating to the west limb. No noteworthy activities are expected in the next 24 hours. The position of NOAA 12800 on January 31 at 04:30 UT is: N18W64 (833", 341") 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 at a very low level. The visible solar disk remains spotless. The target plage region NOAA 12800 was the source of two B-class flares (a B2.5 and a B3.8) in the past 24 hours. 12800 is in its decay phase. Only very low activities are likely in the next 24 hours. The position of NOAA 12800 on January 30 at 04:30 UT is: N18W51 (721", 360") 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 target region NOAA 12800 produced the largest event of the period, a B3.4 flare at 1/28/22:58 UT. 12800 has decayed to a plage region, losing all of its sunspots. Now the visible solar disk is spotless. No significant activities are expected in the next 24 hours. The position of NOAA 12800 on January 29 at 04:30 UT is: N18W38 (572", 374") 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 at a very low level. The largest event in the past 24 hours was a B1.0 peaking at 21:58 UT yesterday from a plage region in the north east quadrant (N19E13). Today the target will switch to a newly numbered region NOAA 12800. 12800 has a beta/B-type configuration and shows some flux emergence followed by cancellation. Only very low level activities are likely in the next 24 hours. The position of NOAA 12800 on January 28 at 08:30 UT is: N19W25 (390", 400") 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 very low level. The largest event in the past 24 hours was a B1.3 (also the only B-class event since the last message), produced by the target region NOAA 12799. 12799 has rotated over the west limb but with some overlying loops still visible. We will watch this region for a further 24 hours. Only very low level activities are likely in the following 24 hours. The position of NOAA 12799 on January 27 at 08:30 UT is: N23W88 (895", 381") 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 target region NOAA 12799 was classified as a beta/D-type region and produced a B1.6 flare in the past 24 hours. 12799 is rotating over the west limb and fragmenting its sunspots. It seems to enter the decay phase. Low B-class activities are still likely in the next 24 hours. The position of NOAA 12799 on January 26 at 08:30 UT is: N22W75 (873", 386") 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, Yesterday's target NOAA 12798 has decayed to a plage region. Today the target will switch to NOAA 12799. 12799 has produced 5 B-class flares since the last message, with the largest one being a B5.0 at 06:31 UT today. This region is rotating to the west limb and emerging positive and negative fluxes. More B-class flares are expected, with a light chance of a low C-class activity in the next 24 hours. The position of NOAA 12799 on January 25 at 08:30 UT is: N23W64 (807", 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.

Dear Collaborators, The target region NOAA 12798 produced a B3.0 flare at 23:34 UT on January 23 (the only B-class event in the past 24 hours). 12798 has decayed to an alpha/A-type region. Only minor activities are likely in the following 24 hours. The position of NOAA 12798 on January 24 at 16:30 UT is: S16W05 (81", -179") 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 very low. The largest X-ray event was a B1.3 at 00:02 UT today (also the only B-class event in the past 24 hours), produced by the target region NOAA 12798. There are three regions with sunspots in the visible solar disk now, with the other two regions NOAA 12797 (alpha/H-type, S18W01) and 12799 (beta/B-type, N21W40) being flare quiet. The target NOAA 12798 remains its beta/C-type configuration and has entered the decay phase. Low B-class activities are still possible in the next 24 hours. The position of NOAA 12798 on January 23 at 16:30 UT is: S16E08 (-130", -181") 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 target region NOAA 12798 (the original trailing spots of NOAA 12797) has produced two B1 flares since the last message. 12798 is remaining its beta/C-type configuration with slightly increasing in number of spots but decreasing in sunspot area. Additional low B-class activities are likely in the next 24 hours. The position of NOAA 12798 on January 22 at 12:30 UT is: S16E27 (-426", -191") 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.
