MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Dec '17

31 Dec '17

Dear RHESSI Collaborators, Solar activity continues at very low levels. The small compact region in the northeast quadrant has remained quiescent and unnumbered. The underlying bipolar plage shall remain the target region with no increase in activity expected over the next 24 hours. The approximate position of the target region on 31-Dec-2017 at 14:30 UT is: N15E49, ( -711", 285" ) 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 RHESSI Collaborators, Solar activity continues at background levels. The target region in the northeast quadrant has remained quiescent and appears to be spotless. The corresponding plage region shall be the target for a further 24 hours although no significant change in activity is expected. The approximate position of the target region on 30-Dec-2017 at 12:30 UT is: N15E64, ( -845", 273" ) 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 RHESSI Collaborators, Solar activity continues at low levels. NOAA 12692 has remained quiescent and is now on the western limb. A new compact region has appeared on the northeast limb and was the source of a B8.3 flare at 22:25 UT yesterday. Its precise magnetic configuration is unknown at this time but it shall be the new target region. Further isolated low level events possible. The approximate position of the target region on 29-Dec-2017 at 16:30 UT is: N13E79, ( -934", 228" ) 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 RHESSI Collaborators, Solar activity remains unchanged. NOAA 12692 has now been downgraded to an alpha region as it approaches the northwest limb. The region continues to decay but shall remain the target region for a further 24 hours. No significant increase in activity expected. The position of NOAA 12692 on 28-Dec-2017 at 12:30 UT is: N17W53, ( 746", 310" ) 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 RHESSI Collaborators, Solar X-ray flux has remained below the B1 level since the last message. NOAA 12692 is almost completely spotless but retains bright H-alpha emission. It shall continue to be the target region although no significant increase in activity is expected over the next 24 hours. The position of NOAA 12692 on 7-Dec-2017 at 16:30 UT is: N18W45, ( 657", 330" ) 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 RHESSI Collaborators, Quiet-Sun conditions persist. NOAA 12692 has remained quiescent since the last message and appears to be in decay. It shall continue to be the target region with a slight chance of an isolated low-level event over the next 24 hours. The position of NOAA 12692 on 26-Dec-2017 at 12:30 UT is: N18W30, ( 465", 335" ) 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 RHESSI Collaborators, Solar activity continues at low levels. The largest event since the last message was a B1.6 flare at 07:11 UT today from target region NOAA 12692. The region retains its simple beta configuration with some polarity mixing in its core. Chance for an additional isolated low level event over the next 24 hours. The position of NOAA 12692 on 25-Dec-2017 at 12:30 UT is: N18W16, ( 256", 337" ) 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 RHESSI Collaborators, Solar activity continues at very low levels. The largest event since the last message was a B3.3 at 06:24 UT on December 23 produced by the target region NOAA 12692. 12692 remains its D-type/beta classification and continues showing mixed polarities in its leading and also intermediate portions. Low B-class activities are likely in the next 24 hours. The position of NOAA 12692 on December 24 at 02:30 UT is: N18E02 (-32", 335") 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 RHESSI Collaborators, Solar activity has been at a very low level. The largest event since the last message was a B3.0 at 11:36 UT on December 22 produced by the target region NOAA 12692. 12692 remains its D-type/beta configuration. It is showing some mixed polarities in its leading portion. Low B-class activities are possible in the next 24 hour period. The position of NOAA 12692 on December 23 at 04:30 UT is: N18E13 (-209", 333") 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 RHESSI Collaborators, The target region NOAA 12692 was the source of 5 B-class events since the last message, the largest one being a B7.2 at 01:40 UT on December 22. 12692 has been classified as a beta/D-type sunspot group. It is showing a positive flux emergence in its negative leader spots. Additional B-class activities are expected with a slight chance of low C-class event in the following 24 hours. The position of NOAA 12692 on December 22 at 04:30 UT is: N18E27 (-422", 328") 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.
