MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Sep '13

30 Sep '13

Dear RHESSI Collaborators, Solar flare activity is at a low level. A C1.2 flare was released due to a filament lift-off (~N10W33) that spanned the region between decayed NOAA 11836 and yesterday's target region (NOAA 11850) on 29-Sep-2013 at 23:39 UT. The flaring structure appeared to be magnetically connected to both NOAA regions. Also, the main polarity separation line within NOAA 11850 has strengthened somewhat. B-class activity is possible, with a slight chance for a further low C-class event. The position of NOAA 11850 on 30-Sep-2013 at 17:00 UT is: N10W69, ( 884", 126" ) 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 flare activity is at a low level. A C1.6 flare was released from a region over the West limb (NOAA 11853) on 29-Sep-2013 at 01:27 UT. Yesterday's target region (NOAA 11850) has not evolved significantly, exhibiting a beta magnetic classification. However the target was also the source of a C1.6 flare on 29-Sep-2013 at 05:25 UT. NOAA 11852 and 11850 are near by and may be destabilising each other. B-class activity is possible, with a slight chance for a further low C-class event. The position of NOAA 1850 on 29-Sep-2013 at 18:00 UT is: N10W56, ( 783", 103" ) 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 very low level. Target region NOAA 1850 is slowly decaying - its sunspot group is now classified a magnetically simple D-type/beta. All regions on the visible solar disk are stable. No significant flare events expected anytime soon. The position of NOAA 1850 on Sept. 28 at 15:30 UT is: N10W39 (Solar X =596", Solar Y = 078") 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, Quiet solar conditions prevail. Target region NOAA 1850 was the source of a few minor B-class events in the past 24 hours. The background x-ray flux is at a low B2 level. 1850 has decayed somewhat since the last message but still has a weak beta-gamma magnetic configuration. B-class events expected with only a slight chance of an isolated C-class event in the next 24 hours. The position of NOAA 1850 on Sept. 27 at 11:30 UT is: N10W24 (Solar X = 385", Solar Y = 062") 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. NOAA 1850 is maintaining its D-type/beta-gamma sunspot group. 1850 was the source of a few B-class events since the last message. B-class events expected with the chance of a C-class event in the next 24 hours. The position of NOAA 1850 on Sept. 26 at 11:30 UT is: N09W10 (Solar X = 165", Solar Y = 037") 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. Target region NOAA 1850 produced several B-class events in the past 24 hours. 1850 has increased its sunspot area and count and magnetic complexity. It is currently displaying a D-type/beta-gamma sunspot group. B-class events expected with a C-class event probable in the next 24 hour period. The position of NOAA 1850 on Sept. 25 at 10:45 UT is: N09E03 (Solar X = -050", Solar Y = 035") 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 was at a low level for the past 24 hours. The largest event was a B8.1 at 09/24/02:09 UT produced by target region NOAA 1850. New flux is emerging just north of the old leader sunspot. There is an increased chance of C-class activity in the next 24 hour period. The position of NOAA 1850 on Sept. 24 at 11:30 UT is: N10E20 (Solar X = -324", Solar Y = 058") 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 background x-ray flux is flat- lined at the B2.0 level. The largest event in the past 24 hours was a B6.0. Its source region was target region NOAA 1850. 1850 has a C-type/beta sunspot group and is slowly decaying. No significant flare activity is expected anytime soon. The position of NOAA 1850 on Sept. 23 at 15:30 UT is: N10E30 (Solar X = -473", Solar Y = 066") 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.
