MM#009 Default Target
by Max Millennium Chief Observer 30 Apr '20

30 Apr '20

Dear Collaborators, There are now three numbered active regions on the visible solar disk, with a possible fourth emerging in the northeast quadrant. NOAA 12760 was the source of several A-class flares since the last message, while NOAA 12762 in the northwest quadrant produced a B1.3 flare at 12:09 UT today. NOAA 12762 has a highly inclined magnetic neutral line but its sunspots have almost decayed. NOAA 12760 shall therefore continue to be the target region for a further 24 hours, with additional A-level activity possible. The position of NOAA 12760 on 30-Apr-2020 at 13:30 UT is: S06W25, ( 401", -36" ) 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 newly emerged region in the southwest quadrant, NOAA 12761, was the source of an A4.0 flare at 05:19 UT today, but has already decayed significantly. Another ERF with a bipolar configuration has appeared in the northwest quadrant since the last message. NOAA 12760 has remained quiescent but shall be the target region for a further 24 hours, with no significant change in activity expected. Also include NOAA 12761 in your field of view if possible. The position of NOAA 12760 on at UT is: S06W11, ( 181", -29" ) 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 conditions remain unchanged since the last message. NOAA 12760 appears to be in decay and is now classified as an alpha region. A cycle 24 region has also emerged in the southwest quadrant. It has a beta sunspot configuration but remains unnumbered. NOAA 12760 shall continue to be the target region, but also include the EFR in your field of view if possible. No significant increase in activity expected over the next 24 hours The position of NOAA 12760 on 28-Apr-2020 at 07:30 UT is: S07E06, ( -99", -43" ) 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 remains at extremely low levels. NOAA 12760 has remained quiescent since the last message, but retains its beta/B-type configuration. It shall continue to be the target region although no change in activity is expected over the next 24 hours. The position of NOAA 12760 on 27-Apr-2020 at 07:30 UT is: S07E20, ( -324", -46" ) 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 continues to be extremely low. The target region has now developed into newly numbered NOAA 12760, a beta/B-type sunspot group. No flares have occurred since the last message, with no change in flaring activity expected over the next 24-hour period. The position of NOAA 12760 on 26-Apr-2020 at 16:00 UT is: S07E28 , ( -446", -49" ) 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 remains at an extremely low level. The target region in the South East quadrant has emerged a small amount of magnetic flux in the past 24 hours and has formed 2 pores (1 in each of its polarities). No X-ray flares have occurred since the last message, with no changes in flaring activity expected in the following 24 hours. The approximate position of this region on 25-Apr-2020 at 20:00 UT is: S06E41 , ( -624", -41" ) 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 continues to be extremely low, with the visible solar disk remaining spotless. The small weak magnetic flux region in the South East quadrant has lost its pore and produced a few A-class events since the last message. No change is expected in flaring activity over the next 24-hour period. The approximate position of this region on 24-Apr-2020 at 17:00 UT is: S06E57 , ( -798", -57" ) 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 remains at an extremely low level. There are no spot regions on the visible solar disk, but the target region in the South East quadrant with compact bright EUV loops does display a small pore. No change in flare activity is expected in the following 24 hours. The approximate position of this region on 23-Apr-2020 at 14:00 UT is: S07E73 , ( -906", -92" ) 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 continues to be extremely low, with no spots on the solar disk. The target compact bright EUV-loop region has now rotated over the South East limb, but no change in flaring activity is expected over the next 24-hour period. The approximate position of this region on 22-Apr-2020 at 14:00 UT is: S08E90 , ( -945", -132" ) 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 remains at an extremely low level, with no spots on the solar disk. A set of compact, bright EUV loops are beginning to become visible over the South East limb near to the location previously chosen as the target region. No change in flaring activity is expected in the following 24 hours. The approximate position of this region on 21-Apr-2020 at 14:00 UT is: S08E90 , ( -945", -132" ) 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.
