MM#009 Default Target

MM#009 Default Target Dear Collaborators, The target region, NOAA 2733, has completed west limb passage but it is still the source of several limb occulted B-class events. The largest was a B7.2 at 01/31/00:58 UT. 2733 will remain the target for the next 24 hours. There is a region located just beyond the northeastern limb at N08 that produced a limb occulted B1.3 event at 01/31/15:43 UT. This region will most likely be the default target tomorrow. The position of NOAA 2733 on January 31 at 14:30 UT is: N04W91 (Solar X = 970", Solar Y = 065") 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 2733 was the source of numerous B-class events and 3 C-class events since the last message. The largest C-class event was a C5.2 at 01/30/06:11 UT. 2733 is now too close to the northwestern limb to ascertain its magnetic configuration but it is likely that the emerging opposite trailing positive polarity flux joined the leading sunspot's negative polarity penumbra to form a small magnetic delta configuration. B-class events probable with the chance of another C-class event in the next 24 hour period. The position of NOAA 2733 on January 30 at 14:30 UT is: N05W85 (Solar X = 966", Solar Y = 093") 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 2733 was the source of numerous B-class events and an isolated C1.9 event at 01/29/10:31 UT. Trailing positive polarity flux emerged adjacent to the southern edge of the large leading negative polarity sunspot's penumbra resulting in an increase in activity located just south of the leading sunspot. B-class activity probable with a slight chance of another isolated C-class event in the next 24 hours. The position of NOAA 2733 on January 29 at 18:00 UT is: N06W72 (Solar X = 922", Solar Y = 131") 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 2733 has decayed significantly especially within its intermediate and trailing sunspots. 2733 is now displaying a C-type sunspot group with a beta magnetic configuration. The largest x-ray event since the last message was a B1.1 at 01/28/01:04 UT. A- and B-class events are possible with only a slight chance of an isolated C-class event in the next 24 period. The C5.0 event that 2733 produced on 01/26/2019 at 13:22 UT was the largest event since the C8.1 event produced by NOAA 2699 on February 7, 2018. The position of NOAA 2733 on January 28 at 14:30 UT is: N05W57 (Solar X = 815", Solar Y = 137") 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 12733 produced a few A- and B-class events in the past 24 hours, the largest being a B8.6 at 16:14 UT yesterday. 12733 retains its beta/D-type sunspot group. It is still emerging some new magnetic fluxes. More B-class activities are expected with a chance of an isolated low C-class flare in the next 24 hour period. The position of NOAA 12733 on January 27 at 14:30 UT is: N06W43 (662", 171") 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 has increased. The largest event since the last message was a C5.0 at 13:13 UT today (only two hours ago) produced by the target region NOAA 12733. 12733 was also the source of eight low level B-class flares. This region retains its beta/D-type configuration, but increasing in sunspot area and number of spots. It is emerging some opposite polarity flux in its leading portion. Further B-class activities are expected with a chance of another C-class event in the next 24 hours. The position of NOAA 12733 on January 26 at 14:30 UT is: N06W29 (471", 184") 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 12733 was the source of numerous (more than 20) A- and B-class events in the past 24 hours. The largest event of the period was a B6.9 at 01/25/04:05 UT. 12733 has been classified as a beta/D-type configuration, retaining its sunspot area and number of spots. It appears to continue showing magnetic cancellations in its intermediate portion. Further B-class flares are expected in the next 24 hours. The position of NOAA 12733 on January 25 at 14:30 UT is: N06W16 (268", 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.

Dear Collaborators, The target region NOAA 12733 was the source of several A-class flares in the past 24 hours. 12733 remains its beta/ C-type classification, but slightly increasing in sunspot area and number of spots. It still shows some mixed polarities in its intermediate portion. Further A-class activities are expected in the following 24 hours. The position of NOAA 12733 on January 24 at 14:30 UT is: N06W01 (16", 193") 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 has been designated as NOAA 12733 with a C-type/beta magnetic configuration. 12733 has produced several low A-class flares. It is still emerging magnetic flux and shows some mixed polarities in its intermediate portion. more A-class flares are expected in the next 24 hours. The position of NOAA 12733 on January 23 at 14:30 UT is: N06E13 (-218", 189") 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 an extremely low level. No flares occurred in the past 24 hours. Yesterday's plage target did not show any notable activities and seems to be under its final decay phase. Today we will watch a new region emerged two days ago, which now is developing some tiny spots. this region displays small EUV jets continuously. Very low activities are likely in the following 24 hours. The approximate position of the target on January 22 at 14:30 UT is: N05E27 (-480", 150") 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.
