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

13 Aug '13

Dear RHESSI Collaborators, The level of solar activity is low. Since yesterday's message, NOAA 11809 was responsible for three C-class events, including the largest flare of the previous 24 hours (a C2.8 flare on 13-Aug-2013 at 11:46 UT). However, yesterday's target region, NOAA 11817, still maintains the largest spot area on disk. The delta spot at its center has separated, but the region still exhibits some evidence for a gamma configuration and the continues to emerge flux within its leading portion. Additionally, nearby NOAA 11819 appears to be strongly magnetically connected and may further destabilise NOAA 11817. C-class activity is likely, with a chance for an isolated low M-class event. The position of NOAA 11817 on 13-Aug-2013 at 17:00 UT is: S23W02, ( 33", -469" ) 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 moderate. NOAA region 11818 has continued to emerge flux but remains mainly bipolar. The region was only responsible for B-class activity. On the other hand, yesterday's target region, NOAA 11817 has also continued to emerge further flux: two bipolar structures are currently emerging adjacent to each other in the trailing and intermediate portions of the region. This has caused a delta spot to form at its center. There is evidence for shearing along the region's strong horizontal polarity separation line. In addition to a number of C-class events, NOAA 11817 was responsible for an M1.5 flare on 12-Aug-2013 at 10:41 UT. If the negative portion of the delta spot continues to grow, large flares may be expected. At this time, further high C-class activity is expected with a chance for further M-class events. The position of NOAA 11817 on 12-Aug-2013 at 17:30 UT is: S22E13, ( -191", -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 increased over the past 24 hours. The newly emerged region near the eastern limb, now designated as NOAA 11818, was the source of two additional C1 flares since the last message. However, another EFR in the southeast quadrant, NOAA 11817, has also produced multiple B- and C-level events, including a C2.0 flare at 14:18 UT today. NOAA 11817 is classified as a beta/C-type region and shall be the new target region. Further C-level activity expected as the region develops. The position of NOAA 11817 on 11-Aug-2013 at 13:00 UT is: S22E26, ( -385", -442" ) 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 11810 has now almost completely decayed. A new, as yet unnumbered, region on the eastern limb was the source of a C2.0 flare at 20:13 UT yesterday, which appears to have been associated with a CME. The region is still too close to the limb to ascertain its magnetic configuration but it shall be the new target region. Chance for additional C-level activity as it rotates on to the disk. The position of the target region on 10-Aug-2013 at 13:00 UT is: S05E72, ( -896", -115" ) 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 steady at the low B-level, with events from both NOAA 11810 and 11813 since the last message. Although NOAA 11810 continues to decay it shall remain the target region for a further 24 hours. Additional isolated low-level events possible. The position of NOAA 11810 on 9-Aug-2013 at 13:00 UT is: S25W41, ( 564", -470" ) 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 11810 is now in decay but has continued to produce B-level activity, the largest being a long-duration B6.3 flare beginning at 17:13 UT yesterday. A new alpha region on the southeast limb, NOAA 11814, has also been the source of some minor B-class flares. NOAA 11810 shall remain the target region for a further 24 hours. Additional low-level events possible. The position of NOAA 11810 on 8-Aug-2013 at 13:00 UT is: S25W27, ( 390", -482" ) 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 X-ray flux remains steady around the B2 level. The target region, NOAA 11810, remains largely unchanged and was the source of a B4.2 flare at 03:42 UT today. Further isolated low-level events possible. The position of NOAA 11810 on 7-Aug-2013 at 13:00 UT is: S26W14, ( 206", -503" ) 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 very low levels. NOAA 11810 continues to develop gradually and is now classified as having a beta configuration. The largest event produced since the last message was a B3.6 flare at 19:01 UT yesterday. Additional isolated minor events possible. The position of NOAA 11810 on 6-Aug-2013 at 13:00 UT is: S26W02, ( 29", -505" ) 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 very low levels. The target region, NOAA 11810, continues to show signs of flux emergence in its trailing portion but remains quiescent. No significant increase in activity expected over the next 24 hours. The position of NOAA 11810 on 5-Aug-2013 at 13:00 UT is: S26E12, ( -177", -502" ) 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. There has been no significant flare activity since the previous message. Yesterday's target region, NOAA 11806, has weakened and the two polarities have separated, somewhat. There is evidence for new flux emergence within NOAA 11810. The region exhibits ongoing spot emergence within its intermediate portion, and now shows some evidence of a gamma configuration. Low B-class activity is expected with a chance for a high B-class event. The position of NOAA 11810 on 4-Aug-2013 at 18:00 UT is: S25W42, ( 571", -466" ) 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.
