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

10 Sep '13

Dear RHESSI Collaborators, The visible solar hemisphere is almost spotless. NOAA 11838 is in decay and now only comprises a tiny alpha spot. The only event of note since the last message was a B4.1 flare at 04:12 UT today, possibly associated with a small filament eruption to the east of the target region. No additional activity expected over the next 24 hours. The position of NOAA 11838 on 10-Sep-2011 at 13:05 UT is: S04E07, ( -116", -185" ) 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. NOAA 11838 was the source of a B4.1 flare at 16:29 UT yesterday but remains unchanged in terms of size and complexity. It shall continue to be the target region although no significant increase in activity is expected. The position of NOAA 11838 on 9-Sep-2013 at 13:05 UT is: S03E19, ( -310", -163" ) 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 X-ray flux has decreased to the low B-level with both NOAA 11836 and NOAA 11837 about to rotate off the visible solar disk. The only remaining active region is NOAA 11838, a small alpha region in the southeast quadrant. This shall be the new target region although no increase in activity is expected. The position of NOAA 11838 on 8-Sep-2013 at 13:05 UT is: S05E33, ( -518", -183" ) 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 with no events of note since the last message. NOAA 11837, now on the western limb, shall remain the target region for a further 24 hours although no significant increase in activity is expected. The position of NOAA 11837 on 7-Sep-2013 at 15:35 UT is: S16W82, (906", -276" ) 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 low levels. NOAA 11836 and NOAA 11837 both remain unchanged in terms of size and complexity, and both have produced isolated low C-class flares over the past 24 hours. NOAA 11837 shall remain the target region with a chance for additional isolated low-level events as it approaches the western limb. The position of NOAA 11837 on 6-Sep-2013 at 13:05 UT is: S16W69, ( 855", -301" ) 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 low levels with some minor events emanating from NOAA 11836 since the last message. The target region NOAA 11837 has remained quiescent but continues to show signs of flux emergence. Possibility of additional low level events from NOAA 11837 over the next 24 hours. The position of NOAA 11837 on 5-Sep-2013 at 13:05 UT is: S15W55, ( 754", -311" ) 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 increased due to C-class flares emanating from both NOAA 11834 and NOAA 11837 over the past 24 hours, the largest being a C3.6 flare from NOAA 11837 at 04:13 UT today. NOAA 11834 has begun to decay as it approaches the western limb and so NOAA 11837 shall become the new target region. NOAA 11837 has a simple bipolar configuration but has doubled in size since the last message. Further C-level activity possible. The position of NOAA 11837 on 4-Sep-2013 at 13:05 UT is: S16W40, ( 589", -349") 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 low levels. The target region, NOAA 11834, has produced additional B-class events since the last message, including a B8.8 at 14:14 UT today. The region continues to show signs of flux emergence and maintains its beta-gamma configuration. Further B-level activity expected with chance for an isolated C-class flare as the region approaches the western limb. The position of NOAA 11834 on 3-Sep-2013 at 19:35 UT is: N12W62, ( 822", 141" ) 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 low. A new bipolar AR is emerging near S15W15. Yesterday's target (NOAA 11834) has produced B-class activity since the previous message (a long duration ~B5 event beginning on 2-Sep-2013 at ~11:00 UT), likely due to ongoing flux emergence in its intermediate portion. Further high B-class activity is expected with a chance for an isolated C-class event. The position of NOAA 11834 on 2-Sep-2013 at 19:30 UT is: N12W55 = (761", 129") 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 low. Yesterday's target (NOAA 11836) has not produced further significant activity and its magnetic structure has simplified. On the other hand NOAA 11834 was responsible for a number of B- and a C-class event (a C1.8 flare on 1-Sep-2013 at 14:20 UT) since the previous message. The region has emerged some flux in its intermediate portion and now exhibits a mixed polarity configuration. Further high B-class activity is expected with a chance for a further isolated C-class event. The position of NOAA 11834 on 1-Sep-2013 at 18:30 UT is: N13W40, ( 600", 124" ) 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.
