MM#009 Default HESSI Target
by Max Millennium Chief Observer 22 Aug '11

22 Aug '11

Dear RHESSI Collaborators, Solar activity remains at mid-low levels. There have been numerous B class flares produced by NOAA 11271 and 11272 along with two low C class flares. There are two new active regions on the east limb - NOAA 11274 and 11275. 11274 appears to be in decay although it is unclear whether 11275 is emerging or decaying at this point in time. Although 11271 and 11272 are also in their decay phases, 11271 will continue to be todays target as it is the largest region on disk with the most number of sunspots. C class activity is possible. The position of NOAA 11271 on 22-Aug-2011 15:30 UT is: N16W10 ( 158", 151" ) 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. NOAA 11271 produced the largest flare of the last 24 hours - a C2.9 - at 23:00 UT. There is a newly numbered region near the north east limb, NOAA 11274, whose magnetic topology is difficult to determine due to its proximity to the limb. As such, today's target will remain NOAA 11271. Although clearly in decay, this region is now at disk center and is retaining its penumbral sunspots and some of its magnetic complexity. C-class activity possible. The position of NOAA 11271 on 21-Aug-2011 15:30 UT is: N17E1 ( -10", 167") 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 although NOAA 11271 and 11272 have produced multiple B class flares between them. Both regions appear to be in the early stages of decay with signs of fragmentation particularly clear in 11271 which has also lost its delta classification. Despite this, 11271 will continue to be todays target as it retains a beta-gamma classification and has three large, bipolar sunspots all of which have strong penumbra. C class activity is possible over the next 24 hours. The position of NOAA 11271 on 20-Aug-2011 15:30 UT is: N17E14 ( -217", 171" ) 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, Activity levels have been low over the past 24 hours with only minor B class flares produced. A new region - NOAA 11273 - has emerged in the south west quadrant and appears to be reasonably simple and compact at this time. NOAA 11272 remains largely unchanged and may still be the source of some mid size flares. NOAA 11271 will continue to be the target of choice today. It is holding its large, complex structure and retains its beta-gamma-delta classification. The position of NOAA 11271 on 19-Aug-2011 15:30 UT is: N16E29 ( -443", 165" ) 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 moderate levels with continued C class activity from NOAA 11271 and 11272. Although both regions are likely to flare, NOAA 11271 will continue as today's target. Its beta-gamma-delta magnetic configuration, bright H-alpha along the magnetic inversion line and multiple large, penumbral sunspots make it the best candidate for >=M class activity. The position of NOAA 11271 on 18-Aug-2011 15:30 UT is: N16E41 ( -599", 178" ) 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, Activity levels are increasing slightly with the rotation of NOAA 11272 onto the disk in addition to 11271. These two regions, both in the eastern hemisphere, have been producing C-class activity over the past 24 hours. Although 11272 does not share the magnetic complexity or the number of sunspots as 11271, it is still a large, flare producing region that is bright in H-alpha. However, NOAA 11271 remains the most likely source of a large flare. With its multipolar magnetic field configuration and large, filamentary penumbral spots, this region will continue to be todays target. Continued C class flares probable with a possibility of some M class activity. The position of NOAA 11271 on 17-Aug-2011 15:30 UT is: N15E54 ( -742", 180" ) 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, Activity is beginning to increase as NOAA 11271 and the still unnumbered region on the south east limb rotate onto the disk. NOAA 11271 is showing signs of significant complexity: multiple large sunspots and multipolar topology. This region which is bright in H-alpha, EUV and X-rays will most likely continue to produce C class activity. In addition, some M-class activity may be possible. The position of NOAA 11271 on 16-Aug-2011 15:30 UT is: N17E65 ( -822", 230" ) 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 solar disk continues to be very quiet today. However, there are now two regions approaching the east limb - one in the north and one in the south. Both of these regions have produced occulted C flares in the past 24 hours are are likely to continue to do so. Today's target will continue to be the newly numbered NOAA 11271 on the north eastern limb as STEREO B observations indicate that it is slightly closer to the solar limb. In addition, it is possible to ascertain the presence of at least one large sunspot, although the magnetic complexity remains indeterminate. The position of NOAA 11271 on 15-Aug-2011 15:30 UT is: N11E87 ( -929", 174" ) 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, All of the active regions on disk are in their decay phases with none showing much promise of significant flaring activity. However, a B class flare was observed from a highly occulted active region on the east limb at approximately 09:45 UT. This region may be the return of NOAA 11260 which produced a huge number of C and M class flares during its previous passage. As such, todays target will be the east limb at the position of this active region as it is the most likely source of flaring activity in the next 24 hours. The position of the target on 14-Aug-2011 at 16:30 UT is: N17E90 ( -905", 274" ) 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 very low levels with no significant flares in the past 24 hours. As such, today's target will continue to be NOAA 11270, although like the other regions on disk, it too appears to be in the early stages of decay. No significant flares expected in the next 24 hours. The position of NOAA 11270 on 13-Aug-2011 15:30 UT is: N23E32 ( -463", 284" ) 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.
