MM#009 Default HESSI Target
by Max Millennium Chief Observer 20 Sep '17

20 Sep '17

Dear RHESSI Collaborators, Solar activity is very low. A new spotted region has rotated over the South East limb in the past 24 hours, likely to be the return of NOAA regions 12675/12676. This region has produced several B-class flares since the last message, but remains too close to the limb to confirm its magnetic classification. Further B-class activity is expected in the following 24-hour period. The approximate position of this region on 20-Sep-2017 at 20:00 UT is: S14E78, ( -906", -254" ) 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. NOAA 12680 remains the only spotted region on disk and has decayed marginally over the past 24 hours, decreasing slightly in spot area. This region is again designated an alpha/H-type sunspot group classification. No flares have occurred since the last message. An isolated low B-class flare may be possible in the next 24 hours. The position of NOAA 12680 on 19-Sep-2017 at 14:30 UT is: N08W48, ( 705", 54" ) 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. NOAA 12680 has again maintained number of spots and area over the past 24 hours, continuing to be classified as an alpha/H-type sunspot group. No flares have occurred since the last message. Low B-class flares may be possible over the following 24-hour period. The position of NOAA 12680 on 18-Sep-2017 at 21:30 UT is: N08W39, ( 596", 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 RHESSI Collaborators, The level of solar activity continues to be extremely low. The target region remains the only spotted region on disk. NOAA 12680 has slowed in its decay phase, maintaining number of spots and area. This region continues to be classified as an alpha/H-type sunspot group, while no flares have occurred since the last message. Low B-class flares could be possible in the next 24 hours. The position of NOAA 12680 on 17-Sep-2017 at 21:30 UT is: N08W25, ( 400", 25" ) 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 is at an extremely low level. NOAA 12680 remains the only spotted region on disk. This region showed signs of decay with increasing in number of spots while decreasing in spot area. 12680 has continued to be classified as an alpha/H-type sunspot group and no flares have occurred since the last message. Low B-class flares may be possible in the following 24-hour period. The position of NOAA 12680 on 16-Sep-2017 at 23:00 UT is: N08W13, ( 209", 17" ) 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. A-class background soft X-ray flux continues, with NOAA 12680 remaining the target. 12680 was again classified as an alpha/H-type sunspot group with no change in sunspot area over the past 24 hours. No flares have occurred since the last message. B-class activity may be possible over the next 24 hours. The position of NOAA 12680 on 15-Sep-2017 at 13:30 UT is: N08E05, ( -82", 13" ) 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 is at very low levels. The background soft X-ray flux has remained in the A-class range over the past 24 hours. The target will continue to be the only spotted region on disk, NOAA 12680. This region maintained spot area and classification as an alpha/H-type sunspot group since yesterday's message. No flares have occurred in this time. B-class flares are possible in the following 24-hour period. The position of NOAA 12680 on 14-Sep-2017 at 13:30 UT is: N09E18, ( -292", 35" ) 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 very low. Target region NOAA 12680 has grown very slightly in sunspot area, but remains classified as an alpha/H-type sunspot group. This region again produced the largest flare of the period - a C1.5 on 12-Sep-2017 at 19:03 UT. More low C-class activity is possible in the next 24 hours. The position of NOAA 12680 on 13-Sep-2017 at 13:30 UT is: N09E31, ( -486", 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 RHESSI Collaborators, Solar activity has returned to a low level. Yesterday's target NOAA 12674 has now rotated over the North West limb, so the target will switch to NOAA 12680. This region is classified as an alpha/H-type sunspot group, but produced a C3.0 flare on 12-Sep-2017 at 07:22 UT. Further C-class flares are possible in the following 24-hour period. The position of NOAA 12680 on 12-Sep-2017 at 13:30 UT is: N09E45, ( -667", 64" ) 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 has been very high. Yesterday's target NOAA 12673 produced an X8.2 flare on 10-Sep-2017 at 15:35 UT, but it has now rotated over the SW limb. The most complex region on disk is NOAA 12674, which is now approaching the NW limb. C-class activity is possible over the next 24 hours. The position of NOAA 12674 on 11-Sep-2017 at 20:30 UT is: N13W89, ( 928", 215" ) 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.
