MM#009 Default HESSI Target
by Max Millennium Chief Observer 31 Aug '13

31 Aug '13

Dear RHESSI Collaborators, The level of solar activity is low. Yesterday's target (NOAA 11836) has produced a further C-class event that is currently in progress (a ~C2 flare on 31-Aug-2013 at ~17:30 UT). The region's following spots appear to have strengthened somewhat. Further high B-class activity is expected with a chance for a further isolated C-class event. The position of NOAA 11836 on 31-Aug-2013 at 19:00 UT is: N11E13, ( -203", 66" ) 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. NOAA 11835 has further fragmented and has not produced significant flare activity. On the other hand, yesterday's target region (NOAA 11836) was the source of the largest flare since the previous message (a C8.3 flare on 30-Aug-2013 at 02:46 UT). The coronal structure appears to have simplified somewhat since the flare but the photospheric configuration has not changed significantly. Further high B-class activity is expected with a chance for a further isolated C-class event. The position of NOAA 11836 on 30-Aug-2013 at 17:00 UT is: N12E33, ( -503", 99" ) 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 region (NOAA 11835) has shown signs of fragmentation and decay in its leading and following spots. The largest event since the last message was a C1.2 flare released by NOAA 11836 on 29-Aug-2013 at 04:34 UT). NOAA 11836 was also responsible for B-class activity. Although the region does not show the largest spot area on disk, it is surrounded by mixed polarity plage in its southern portion, which may be contributing to its destabilisation. The region has not shown signs of decay and may still be in an unstable state. Its loop configuration seen in X-ray images has not changed dramatically since the C-class flare. Further B-class activity is expected with a chance for an isolated C-class event. The position of NOAA 11836 on 29-Aug-2013 at 18:00 UT is: N10E45, ( -664", 82" ) 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. Since the last message, the largest event was a West-limb flare (a B9.0 flare on 27-Aug-2013 at 15:56 UT). Yesterday's target region (NOAA 11835) has shown some signs of spot development in its trailing portion. The region was responsible for a ~B4.0 flare that is currently in progress (peak at around 17:30 UT). Further B class activity is expected with a chance for high B-class events. The position of NOAA 11835 on 28-Aug-2013 at 18:00 UT is: S10E29, ( -456", -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.

Dear RHESSI Collaborators, The level of solar activity is low. The largest event since the previous message was a B7.7 flare released by NOAA 11834 on 27-Aug-2013 at 08:35 UT. The region is a decayed bipolar feature which may have been destabilised by a new region that has rotated over the East limb (near N10E75). The new region shows evidence of an alpha/H-type magnetic configuration. Yesterday's target (NOAA 11835) has not produced significant activity since the previous message but still shows the largest spot area of the regions on disk. Also, its trailing polarity spots have strengthened, thereby increasing the gradient along its main polarity separation line. B-class activity is expected with a chance for high B-class events. The position of NOAA 11835 on 27-Aug-2013 at 17:30 UT is: S10E41, ( -619", -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, The level of solar activity is very low. No significant activity has occurred since the previous message. Yesterday's target region (NOAA 11830) has rotated over the West limb. Since NOAA 11835 currently exhibits the largest spot area of the regions on disk, it is now designated as the new target region. B-class activity is likely, with a chance for a high B-class event. The position of NOAA 11835 on 26-Aug-2013 at 17:30 UT is: S10E53, ( -752", -233" ) 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 very low. Only B-class flares have occurred since yesterday's message. NOAA region 11830 maintained spot area and number of spots as it rotates towards the West limb. B-class activity is expected in the following 24 hours, with a chance for low C-class events. The position of NOAA 11830 on 25-Aug-2013 at 10:30 UT is: S05W84, ( 940", -95" ) 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 a low level. NOAA 11830 has slowed in its growth since the last message. This region has shown a minor increase in spot area over the past 24 hours, maintained a beta/D-type sunspot group classification and produced a C1.0 flare on 23-Aug-2013 at 16:45 UT. B-class activity is expected over the following 24 hours, with a good chance for further C-class events. The position of NOAA 11830 on 24-Aug-2013 at 10:30 UT is: S05W70, ( 888", -122" ) 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. NOAA 11820 has started to decay in the past 24 hours, decreasing in spot area and number of spots as well as being classified as a beta/D-type sunspot group. NOAA 11820 produced two C-class events since yesterday's message, the largest being a C1.9 flare on 22-Aug-2013 at 23:56 UT that might have been magnetically connected to NOAA 11830. NOAA region 11830 will be the new target as it has shown signs of new flux emergence in the past 24 hours and has formed mature leading and following spots. Further C-class activity is likely in the next 24 hours. The position of NOAA 11830 on 23-Aug-2013 at 10:30 UT is: S06W57, ( 791", -162" ) 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 a low level. NOAA region 11818 has rotated over the West limb and was the source of the largest event in the past 24 hours (a foot-point occulted C4.1 flare on 22-Aug-2013 at 04:49 UT). NOAA 11820 has continued to emerge new magnetic flux, increasing in spot area and number of spots while maintaining a beta-gamma/D-type sunspot group classification. Further C-class activity is likely in the following 24 hours. The position of NOAA 11820 on 22-Aug-2013 at 12:30 UT is: S12W54, ( 751", -263" ) 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.
