MM#009 Default HESSI Target
by Max Millennium Chief Observer 10 Apr '13

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity continues at low levels. Target region NOAA 1718 was the source of several minor C-class events and NOAA 1719, N10E18, produced one minor C-class event since the last message. Both regions have been classified by NOAA as D-type/beta-gamma. 1719 has a reversed polarity magnetic configuration. Additional C-class events probable with a chance of an isolated M-class event as well in the next 24 hour period. The position of NOAA 1718 on April 10 at 13:00 UT is: N21W14 (Solar X = 217", Solar Y = 432") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity remains at a low level with only minor C-class events in the past 24 hours. NOAA 1718 has been the most dynamic since the last message adding sunspot count and area. It is currently classified as a D-type/beta-gamma region. Target region NOAA 1719, N07E31 is mostly unchanged and has been quiescent. The target will switch from 1719 to 1718 today. C-class events expected with a chance of an isolated M-class event in the next 24 hour period. The position of NOAA 1718 on April 09 at 13:00 UT is: N22W01 (Solar X = 015", Solar Y = 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity is at low levels. Target region NOAA 1719 and NOAA 1718, N20E12, are currently the most likely regions on the visible solar disk to produce C-class activity. Both regions have D-type/beta-gamma sunspot groups. A C-class event is possible with a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 1719 on April 08 at 13:00 UT is: N08E45 (Solar X = -672", Solar Y = 204") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, NOAA 1719 increased sunspot count and area and magnetic complexity. The region is now classified a D-type/beta-gamma. It was the source of a few low-level C-class events since the last report. Additional C-class activity is probable with the chance of another M-class event in the next 24 hour period. The position of NOAA 1719 on April 07 at 13:00 UT is: N08E58 (Solar X = -806", Solar Y = 186") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, The target region, now numbered NOAA 1719, was the source of an isolated M2.2 event at 04/05/17:48 UT. 1719 is currently displaying a disappointing H-type/alpha sunspot group but it does have mixed polarites in its non-spot plage. Recently emerged NOAA 1718, N23E37, is producing low-level C-class activity. It is possible that 1719 will produce another isolated M-class event in the next 24 hour period. The position of NOAA 1719 on April 06 at 13:00 UT is: N08E70 (Solar X = -892", Solar Y = 167") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity continues at a low level. The largest event in the past 24 hours was a limb occulted C2.1 event and associated CME at 04/05/06:50 UT. The source region is located beyond the northeastern limb in the location of old NOAA 1692. The target will switch from NOAA 1711 to the NE limb. Another C-class event is possible in the next 24 hour period. The approximate position of the target on April 05 at 12:00 UT is: N10E88 (Solar X = -944", Solar Y = 169") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity is very low. Target region NOAA 1711 is mostly unchanged. 1711 is maintaining its very large leader sunspot with some minor mixed polarity located along the eastern edge of its penumbra. 1711 was the source of a minor C1.7 event at 04/03/18:45 UT. Another C-class event is possible in the next 24 hours. The position of NOAA 1711 on April 04 at 13:00 UT is: S17E16 (Solar X = -253", Solar Y = -182") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity continues at a low level. There were two C-class events in the past 24 hours. Both events were produced by NOAA 1708 (N10W05). 1708 is a small C-type/beta region with an unusual E-W magnetic inversion line. Another C-class event is possible. Target region NOAA 1711 is mostly unchanged and quiescent during the past 24 hours but is maintaining its very large leader sunspot with minor mixed polarities. B-class events probable with a chance of an isolated C-class event. The position of NOAA 1711 on April 03 at 13:00 UT is: S17E28 (Solar X = -432", Solar Y = -189") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity continues at a low level with only minor B-class events detected with most of them produced by an EFR located at N08E29. The target region, NOAA 1711, is now slowly decaying. B-class events probable from 1711 and the EFR with the possibility that 1711 will produce an isolated C-class event in the next 24 hours. The position of NOAA 1711 on April 02 at 13:00 UT is: S20E44 (Solar X = -628, Solar Y = -253") 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.

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity is very low. The largest event in the past 24 hours was a B7.3 at 03/31/15:15 UT. Its source was target region NOAA 1711. 1711 is a C-type/beta region with a very large leader sunspot. B-class events expected with a chance of a C-class event in the next 24 hour period. The position of NOAA 1711 on April 01 at 13:00 UT is: S17E54 (Solar X = -744", Solar Y = -218") 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.
