MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Sep '18

30 Sep '18

Dear RHESSI Collaborators, Solar activity continues at very low levels. Yesterday's target region has now designated as NOAA 12723 with a beta/B-type sunspot group. This region is emerging magnetic flux. Minor activity is likely in the following 24 hours. The position of NOAA 12723 on September 30 at 07:10 UT is: S08W05 (83", -244") 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 level of solar activity is extremely low. The visible solar disk remains spotless. Only some very small scale EUV brightenings show up. Today we will watch one of the brightenings close to the central meridian. small EUV jets are possible in the next 24 hours. The approximate position of the target on September 29 at 07:10 UT is: S10E10 (-120", -200") 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 a background level and the visible solar disk remains spotless. There show up some small brightenings within the target coronal hole. No flaring activity is expected in the next 24 hours. The approximate position of the target on September 28 at 07:10 UT is: S01E41 (-600", -95") 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 at a background level. No noteworthy events occurred on the spotless disk. Yesterday's target prominence/filament seems to disappear. Today we will watch a small "coronal hole" in the southeastern quadrant that is close to the equator. Some bright emissions (especially in AIA 193) show up. No flaring activity is likely in the following 24 hours. The approximate position of the target on September 27 at 07:10 UT is: S02E58 (-760", -90”) 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 extremely low levels. The visible solar disk remains spotless. The target prominence/filament shows some swirling motions and appears to erupt some plasma. Today we will continue to watch this target. No significant activity is expected in the next 24 hours. The approximate position of the target on September 26 at 07:10 UT is: N44E80 (-600", 650") 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 at an extremely low level. The visible solar disk is very clean. Yesterday's target (a plage region) has rotated beyond the west limb. Today we will switch to a limb prominence/filament, which is rotating onto the disk. A cavity appears to form at the limb. No significant activity is expected in the next 24 hours. The approximate position of the target on September 25 at 07:10 UT is: N44E90 (-650", 650") 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 extremely low levels with the GOES soft X-ray flux being flat at ~A3. The visible solar disk is featureless, no spots or filaments. The decaying plage region shall remain the target for a further 24 hours although no flaring activity is expected. The approximate position of the target region on September 24 at 07:10 UT is: N08W75 (910", 90") 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 at very low levels. The decaying plage region has remained quiescent as it approaches the western limb. It shall remain the target region for a further 24 hours although no change in activity is expected. The approximate position of the target region on 23-Sep-2018 at 07:10 UT is: N08W60, ( 825", 75" ) 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 visible solar disk remains spotless. The decaying plage region along the western equator continues to exhibit UV and EUV brightenings, and has developed a mini-filament along its polarity inversion line. It shall continue to be the target region although no significant change in activity is expected over the next 24 hours. The approximate position of the target region on 22-Sep-2018 at 16:10 UT is: N07W54, ( 765", 47" ) 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 visible solar hemisphere is almost featureless. The new target region shall be a weak, decaying plage region along the western equator, which contains a few bright H-alpha kernels. No change in activity is expected over the next 24 hours. The approximate position of the target region on 21-Sep-2018 at 16:10 UT is: N06W41, ( 620", 10" ) 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.
