MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Sep '12

30 Sep '12

Dear RHESSI Collaborators, A newly emerged active region on the north western limb, designated NOAA 11583, was the source of an M1 flare at 04:33 UT today and shall be the new target region. The region is classified as having a beta configuration and may produce further low to intermediate level events before it rotates over the western limb. The position of NOAA 11583 on 30-Sep-2012 at 12:00 UT is: N13W82, ( 924", 198" ) 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 below C-level. The target region NOAA 11579, now classified as a beta region, continues to show signs of flux emergence and is becoming increasingly bright in H-alpha. Chance of an isolated low-level event if the region continues to develop. The position of NOAA 11579 on 29-Sep-2012 at 09:00 UT is: S09E15, ( -242", -258" ) 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 Sun has produced two mid C-level flares in the past 24 hours: one from NOAA 11579 and one due to a filament eruption from NOAA 11577. NOAA 11579 appears to be undergoing new flux emergence in the wake of the leading sunspot and shall be the new target region. Chance for additional isolated low-level events. The position of NOAA 11579 on 28-Sep-2012 at 09:00 UT is: S10E28, ( -441", -265" ) 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 solar conditions continue with the solar X-ray flux remaining steady around the mid-B-level. A large alpha spot has appeared on the southeast limb but has not resulted in any increased activity. NOAA 11580 shall remain the target region for a further 24 hours although no significant increase in activity is expected at this time. The position of NOAA 11580 on 27-Sep-2012 at 09:00 UT is: N17E48, ( -682", 205" ) 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 on the northeast limb has now been designated as NOAA 11580 and was the source of a C4.5 flare at 17:47 UT yesterday. The region is classified as a simple beta region and may produce additional isolated low-level events over the next 24 hours. The position of NOAA 11580 on 26-Sep-2012 at 09:00 UT is: N17E62, ( -809", 226" ) 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 new region on the southeast limb is now designated as NOAA 11579 but has been relatively quiet since rotating on to the visible disk. Yet another, as-yet unnumbered, region has since appeared on the northeast limb producing a number of high B/low C-class flares, including a C3.6 flare at 04:24 UT today. The magnetic configuration of this new target region is uncertain but further low-to-intermediate level events are expected. The approximate position of the new target region on 25-Sep-2012 at 09:00 UT is: N15E78, ( -906", 224" ) 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, NOAA 11575 has remained inactive since the last message and has begun to show signs of decay. A new region rotating on to the south east limb was the source of a long duration C1.7 flare at 15:02 UT yesterday and shall be the new target region. The flare was concurrent with a large scale CME observed in LASCO images indicating possible increased activity over the next 24 hours as the region rotates onto the disk. The approximate position of the new target region on 24-Sep-2012 at 09:00 UT is: S07E78, ( -929", -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, NOAA 11575 has increased in sunspot area over the past 24 hours due to some negative flux emergence within the trailing positive plage, and is now classified as a beta-gamma region. The region has remained quiescent but increased activity is possible if it continues to develop. The position of NOAA 11575 on 23-Sep-2012 at 09:00 UT is: N08E19, ( -309",22" ) 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 low levels. The target region NOAA 11575 remains relatively unchanged in terms of size and complexity. Sporadic B-level events possible. The position of NOAA 11575 on 22-Sep-2012 at 15:00 UT is: N08E28, ( -445", 30" ) 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 target region NOAA 11575 has remained predominantly quiescent since the last message but has shown signs of flux emergence. Isolated low-level events still possible. The position of NOAA 11575 on 21-Sep-2012 at 09:00 UT is: N07E45, ( -670", 33" ) 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.
