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

13 Oct '13

Dear RHESSI Collaborators, NOAA 11861 has remained quiescent since the last message and has been downgraded to a beta-gamma region. NOAA 11865, on the other hand, maintains its beta-gamma-delta configuration and was the source of an M1.7 flare at 00:12 UT today. The region comprises a highly sheared magnetic neutral line and has shown signs of positive flux emergence along its leading edge. NOAA 11865 shall be the new target region with low-to-intermediate level events possible. The position of NOAA 11865 on 13-Oct-2013 at UT is: S22E08, ( -124", -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, Solar activity has returned to low levels since the last message. NOAA 11861 continues to produce sporadic low C-class flares but has not shown any recent signs of development. At this time we are ending the DST Flare Campaign although NOAA 11861 shall remain the target region. Additional isolated low-level events possible. The position of NOAA 11861 on 12-Oct-2013 at 19:35 UT is: S09W05, ( 83", -249" ) 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#019 DST Flare Campaign
by Max Millennium Chief Observer 11 Oct '13

11 Oct '13

Dear RHESSI Collaborators, Solar activity is at moderate levels. A region currently behind the northeast limb was the source of a partially-occulted M1.5 flare at 07:01 UT today but its magnetic configuration is unknown. Both NOAA 11865 and NOAA 11861 have continued to produce C-class flares since the last message. NOAA 11861 shall remain the DST Flare Campaign target region for a further 24 hours. Additional C-level activity likely. The position of NOAA 11861 on 11-Oct-2013 at 19:35 UT is: S10E10, ( -165", -266" ) 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#019 DST Flare Campaign
by Max Millennium Chief Observer 10 Oct '13

10 Oct '13

Dear RHESSI Collaborators, Both NOAA 11865 and NOAA 11861 have produced a number of C1 flares since the last message. NOAA 11865 is now classified as a beta-delta region but has begun to show signs of decay. NOAA 11861, on the other hand, has shown significant development over the past 24 hours and also sports a delta configuration with negative polarity flux embedded in the penumbra of the positive leader spot. NOAA 11861 shall be the target region for tomorrow's DST Flare Campaign between 14:00-17:00 UT. Chance for additional C-level activity. The position of NOAA 11861 on 10-Oct-2013 at 19:35 UT is: S13E25, ( -397", -307" ) 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#019 DST Flare Campaign
by Max Millennium Chief Observer 09 Oct '13

09 Oct '13

Dear RHESSI Collaborators, A newly numbered region near the southeast limb, NOAA 11865, was the source of an M2.8 flare at 01:23 UT today and shall be the new target region. At this time we are implementing MM#019 DST Flare Campaign in support of the Service Mode operations being run at the Dunn Solar Telescope throughout the month of October. The region appears to contain some mixed polarity in its trailing portion and has exhibited some dynamic behavior since the flare. There is an increased possibility of the region producing another C5 flare or greater over the next 24-48 hours. If supporting the DST Flare Campaign, please select NOAA 11865 as your target region and observe between 14:00-17:00 UT when seeing conditions are optimal at the facility. The position of NOAA 11865 on 9-Oct-2013 at 20:35 UT is: S20E61, ( -791", -374" ) 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
by Max Millennium Chief Observer 08 Oct '13

08 Oct '13

Dear RHESSI Collaborators, Solar activity remains at low levels. NOAA 11856 has continued to decay and has been quiescent since the last message. The active region in the southeast quadrant responsible for the current B-level activity has now been designated NOAA 11861 and shall be the new target region. Further B-level activity likely with chance for an isolated C-class flare. If possible, also include the adjacent, unnumbered beta region close the eastern limb in your field of view. The position of NOAA 11861 on 8-Oct-2013 at 11:35 UT is: S13E57, ( -786", -271" ) 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 elevated. There have been a number of B-class events, as well as two C1 flares from a new region on the eastern limb since the last message, although its magnetic configuration is unclear at this time. NOAA 11856, was the source of a C6.2 flare at 03:58 UT today but appears to be in decay. NOAA 11856 shall remain the target region for a further 24 hours with a chance for additional isolated C-level events. The position of NOAA 11856 on 7-Oct-2013 at 15:35 UT is: 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
by Max Millennium Chief Observer 06 Oct '13

06 Oct '13

Dear RHESSI Collaborators, Solar flare activity is at a low level. Since the previous message, a C1 flare was released by a decayed plage region (~S05W10) on 06-Oct-2013 at ~14:00 UT, which does not appear to be likely to produce further activity. Subsequently, a B-class flare was released from a region over the East limb, but its magnetic configuration cannot be gauged. Although yesterday's target has decayed and now exhibits an alpha magnetic classification, in the absence of a more productive region, the target not change for at least one more day. B-class activity is possible. The position of NOAA 11856 on 06-Oct-2013 at 20:00 UT is: N08E20, ( -325", 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.

Dear RHESSI Collaborators, Solar flare activity is at a low level. Since the previous message, NOAA 11857 was responsible for B-class activity. Coronal connectivity between NOAA 11857 and the target region (NOAA 11856) is still evident. Neither region's magnetic and coronal configuration has changed significantly. If the instrument allows, both regions should be included within the FOV. B-class activity is expected with the possibility of an isolated C-class event. The position of NOAA 11856 on 05-Oct-2013 at 20:00 UT is: N08E32, ( -504", 42" ) 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. Since the previous message, a C2.5 flare was released on 04-Oct-2013 at 03:32 UT from yesterday's target region (NOAA 11856). The photospheric and coronal configuration of the target has not changed appreciably since the flare. Nearby NOAA 11857 is mildly active in X-rays and appears to be strongly magnetically connected to the target region, possibly leading to further destabilisation. Continued B-class activity is expected with a further C-class event being likely. The position of NOAA 11856 on 04-Oct-2013 at 20:00 UT is: N07E45, ( -674", 40" ) 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.
