MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Jun '11

30 Jun '11

Dear RHESSI Collaborators, Solar activity is extremely quiet, with no flares today. NOAA 11242 did not continue to grow at the rate at which it emerged and as such, has not evolved significantly in the past 24 hours. However, it will continue to be todays target with some B class activity possible. The position of NOAA 11242 on 30-Jun-2011 15:30 UT is: N17W26 ( 397", 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, There were a series of mid-B class flares yesterday that were produced by NOAA AR 11240, now on the west limb and 11243 - yesterday's target in the north east quadrant. A new region, AR 11242 has emerged quickly at disk center. Continued growth at this rate, with the level of complexity it is already showing would mean high chance of some C-class or even M-class activity in the coming days. The position of NOAA 11242 on 29-Jun-2011 15:30 UT is: N18W12 ( 187", 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, There were three B class flares in the past 24 hours with the largest - a B9 event - coming from NOAA 11236/11239, now behind the limb. The still unnumbered region on the north-east limb produced a smaller B class flare and will continue to be todays target. Although it is difficult to say due to its position, this region shows signs of small sunspots with some dense field regions, though STEREO B images suggest it may have entered its decay phase. The position of the target on 28-Jun-2011 at 16:30 UT is: N15E69 ( -850", 229" ) 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 low with two B class flares produced by NOAA 11236 and 11241 in the past 24 hours. With NOAA 11236 having rotated behind the limb, the target region will switch to the east limb where an unnumbered region is rotating onto the disk. Though the complexity of the region is difficult to specify, it is bright in EUV and is showing large loop structures overlying the region. The position of the target on 27-June-2011 at 16:00 UT is: N15E90, ( -900", 200" ) 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. No significant changes in the level of activity expected anytime soon. The target region is now on the west limb. A minor event is possible before it completes west limb passage. The position of NOAA 1236 on June 26 at 10:30 UT is: N15W80 (Solar X = 898", Solar Y = 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.

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.
