MM#009 Default Target
by Max Millennium Chief Observer 21 Dec '19

21 Dec '19

Dear Collaborators, Solar activity continues at very low levels. The Cycle 25 region in the northeast quadrant has remained quiescent, but has been joined by an emerging Cycle 24 region to the south. The northern region shall be the target region for a further 24 hours, but also include the southern region in your FOV if possible. No significant change in activity expected. The approximate position of the target region on 21-Dec-2019 at 14:30 UT is: N22E36, ( -539", 388" ) 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, GOES X-ray flux has continued at background levels since the last message. The bipolar plage region in the northeast quadrant remains quiescent but shall continue to be the target region. No change in activity expected over the next 24 hours. The approximate position of the target region on 20-Dec-2019 at 08:30 UT is: N22E53, ( -720", 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, Solar activity continues at very low levels. The target region in the northeast quadrant continues to produce small fluctuations in the GOES short-wavelength channel. The region is compact and spotless but is bright in EUV and X-ray emission. Any significant change in activity over the next 24 hours is unlikely. The approximate position of the target region on 19-Dec-2019 at 14:30 UT is: N22E65, ( -820", 375" ) 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. There have been some small increases in the GOES 0.5-4A flux since the last message, possibly due to an emerging flux region in the northeast quadrant. Its magnetic configuration is uncertain at this time, but it shall be the target region for the next 24 hours. No significant increase in activity expected. The approximate position of the target region on 18-Dec-2019 at 12:30 UT is: N22E80, ( -891", 369" ) 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, Quiet-Sun conditions continue. The visible solar disk remains quiescent and featureless. There shall be no default target region today, with no change in activity expected over the next 24 hours.

Dear Collaborators, Solar minimum conditions continue. The visible solar hemisphere remains spotless and devoid of any viable target region. There shall be no default target today with no change in activity expected over the next 24 hours, 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 remains extremely low. There continues to be no sunspots on the visible disk, while no X-ray flares have occurred in the past 24 hours. The target prominence on the South East limb has decreased somewhat in size but remains as the target for a further 24 hours. No change in flaring activity is expected in the following 24-hour period. The approximate position of this region on 15-Dec-2019 at 20:00 UT is: S50E90, ( -626", -746" ) 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 to be at an extremely low level. There are currently no sunspots on the visible disk, and no significant X-ray flares have occurred since the last message. The target prominence on the North East limb has decreased considerably in extent, so the target switches to a prominence on the South East limb. No change in flare activity is expected over the next 24 hours. The approximate position of this region on 14-Dec-2019 at 19:00 UT is: S48E90, ( -652", -724" ) 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 remains extremely low. No X-ray flares have occurred in the past 24 hours. Deep solar minimum conditions prevail, with no spots on the visible disk. The target prominence on the North West limb is no longer visible so the target switches to a small dynamic prominence on the North East limb. No change in flaring activity is expected in the following 24-hour period. The approximate position of this region on 13-Dec-2019 at 18:30 UT is: N37E90, ( -778", 586" ) 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 is at an extremely low level with no X-ray flares having occurred since the last message. Solar minimum conditions continue with no spots on the visible disk. The target ephemeral flux region in the North East quadrant has now disappeared. A new dynamic prominence on the North West limb becomes the target, but no change is expected in flaring activity over the next 24 hours. The approximate position of this region on 12-Dec-2019 at 23:30 UT is: N50W90, ( 626", 746" ) 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.
