MM#009 Default HESSI Target

MM#009 Default HESSI Target Dear RHESSI Collaborators, Solar flare activity has been very low. The target region, NOAA 1236, was the source of the only activity since the last message. 1236 produced two minor B-class events. The largest was a B4.3 at 06/25/10:20 UT. 1236 is mostly unchanged with a C-type/beta sunspot group. No significant solar flare activity expected. The position of NOAA 1236 on June 25 at 20:30 UT is: N17W73 (Solar X = 863" Solar Y = 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, Solar activity has remained quiet for the past 24 hours despite the five numbered active regions on disk. All of these regions appear to be decaying, although a small, unnumbered EFR is emerging at the meridian in the northern hemisphere. If it continues to grow it may produce some mid-size flares. For now, we will continue to observe NOAA 11236 as it approaches the west limb. The position of NOAA 11236 on 24-Jun-2011 at 15:30 UT is: N16W55 ( 744", 241" ) 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 quiet, with no significant flares in the past 24 hours. Although the complexity of NOAA 11236 has been reduced to beta, as the largest and most flare-productive region it will continue to be today's target of opportunity. The position of NOAA 11236 on 23-Jun-2011 15:30 UT is: N16W41 ( 597", 237" ) 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 low today with no major flares occurring in the past 24 hours. There are currently five active regions on disk and, although NOAA 11236 continues to decay slowly, it remains the largest and most complex region. Its leading spot retains its beta-gamma classification and so it will continue to be todays target of opportunity. The position of NOAA 11236 on 22-Jun-2011 at 15:30 UT is: N17W30 ( 449", 251" ) 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 11236 was the source of an eruptive C7 flare earlier today as its large central filament erupted. Although the active region remains largely unchanged, the two spots that once formed the leading sunspot have merged into one large leader spot and have retained the large penumbra. In addition, small scale flux emergence close to the trailing spot, along with a new AR developing to the east of the region makes it a good candidate for further C class activity. The position of NOAA 11236 on 21-Jun-2011 at 15:30 UT is: N17W16 ( 249", 250" ) 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 produced two mid to low C class flares yesterday: a C4 flare from NOAA 11234 on the west limb and a C1.5 from 11237, an alpha region in the south east quadrant. AR 11236 will continue to be today's target at it crosses the meridian. It maintains its beta gamma configuration and mixed polarity leading spot. Further C class flares possible in the next 24 hours. The position of NOAA 11236 on 20-Jun-2011 at 15:30 UT is: N16W03 ( 47", 235" ) 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 11236 continues to decay and was the source of a B9.1 flare at 02:21 UT today. Further low-level activity likely with chance for an isolated C-class flare. The position of NOAA 11236 on 19-Jun-2011 at 10:30 UT is: N17E12, ( -188", 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.

Dear RHESSI Collaborators, Solar activity is at low levels. The C3.9 flare at 23:37 UT yesterday emanated from NOAA 11234. The target region NOAA 11236 has begun to decay and had been downgraded from a beta-delta to a beta-gamma region. There is still a chance for some C-level activity from the target region over the next 24 hours. The position of NOAA 11236 on 18-Jun-2011 at 10:30 UT is: N17E27, ( -411", 257" ) 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 conditions have remained quiet over the past 24 hours with the target region NOAA 11236 producing only B-level events. The region has remained unchanged in terms of size and complexity. C-level activity is still likely with a slight chance of an isolated M-class flare. The position of NOAA 11236 on 17-Jun-2011 at 10:30 UT is: N17E40, ( -582", 261" ) 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 11236 has been upgraded to a beta-gamma region and has almost doubled in size since the last message. The region produced a C7.1 flare at 10:13 UT today. Further C-level activity likely with chance for an isolated M-class flare. The position of NOAA 11236 on 16-Jun-2011 at 10:30 UT is: N17E52, ( -713", 256" ) 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.
