MM#009 Default HESSI Target
by Max Millennium Chief Observer 28 Feb '18

28 Feb '18

Dear RHESSI Collaborators, Solar activity has been at a very low level for the past 24 hours. Only an ~A9 flare was produced by the target region NOAA 12700. 12700 is now classified as a beta/B-type sunspot group. It is showing some mixed polarities in its intermediate portion. Only minor activities are possible in the next 24 hours. The position of NOAA 12700 on 28-Feb-2018 at 08:30 UT is: N06W33 (526", 202") 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 has been designated as NOAA 12700 with a C-type/beta magnetic configuration. 12700 was the source of two B-class flares, a B1.0 at 02/26/11:58 UT and a B3.3 at 02/26/15:48 UT. It continues showing emerging flux. Low B-class activities are expected over the following 24 hours. The position of NOAA 12700 on 27-Feb-2018 at 04:30 UT is: N06W16 (266", 217") 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. Yesterday's target prominence/filament has been stable. Today the target will switch to an emerging flux region (unnumbered yet) in the northwest quadrant. Some tiny spots are emerging in this new region. Minor activities are possible in the next 24 hours. The approximate position of the target region on 26-Feb-2018 at 08:30 UT is: N06W05 (80", 210") 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, Quiescent, spotless conditions continue. The large prominence above the northeast limb is still visible in EUV and X-ray images, with a filamentary component also visible in H-alpha. This shall remain the target region although no significant increase in activity is expected unless the filament erupts. The approximate position of the target region on 25-Feb-2018 at 16:30 UT is: N27E82, ( -855", 451" ) 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 and quiescent. The new target region shall be the large prominence visible above the northeastern limb. No change in activity expected at this time. The approximate position of the target region on 24-Feb-2018 at 14:30 UT is: N24E82, ( -876", 408" ) 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 background levels. The small, compact region approaching the western limb remains quiescent and spotless but shall continue as the target region for a further 24 hours. No change in activity expected at this time. The approximate position of the target region on 23-Feb-2018 at 12:30 UT is: N05W76, ( 938", 113" ) 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 continue. The visible solar disk remains spotless. A small, compact region with a bright X-ray component has emerged in the northwest quadrant and shall be the new target region. No change in solar activity expected over the next 24 hours. The approximate position of the target region on 22-Feb-2018 at 16:30 UT is: N05W62, ( 853", 140" ) 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. Yesterday's small compact target region in the northeast quadrant appears to have decayed slightly but retains a bright EUV component. It shall remain the target region for a further 24 hours although no flaring activity is expected at this time. The approximate position of the target region on 21-Feb-2018 at 14:30 UT is: N05E54, ( -783", 154" ) 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, with the GOES X-ray flux remaining constant around the A3 level. The new target region shall be small plage region rotating on to the eastern limb. No increase in activity is expected at this time. The approximate position of the target region on 20-Feb-2018 at 16:30 UT is: N05E73, ( -926", 118" ) 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. There was a isolated, long-duration B1.1 flare associated with an emerging flux region in the southeast quadrant at 04:58 UT today. The region may continue to develop over the next 24 hours and shall therefore be the new target region. However no significant increase in activity is expected at this time. The approximate position of the target region on 19-Feb-2018 at 12:30 UT is: S05E23, ( -377", 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.
