MM#009 Default HESSI Target
by Max Millennium Chief Observer 24 Jul '11

24 Jul '11

MM#009 Default HESSI Target Dear RHESSI Collaborators, The several regions on the visible solar disk are very quiescent. Solar flare activity is expected to continue at a very low level. The target region (most likely the return of old NOAA regions 1243/1246) has mostly rotated over the NE limb. It appears to have just one small leader sunspot. There is weak surging in the trailing portion. No significant solar flare activity is expected during the next 24 hour period. The position of the target region on July 24 at 15:00 UT is: N19E78 (Solar X = -874", Solar Y = 290") 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, The regions on the disk are decaying. The target will switch from NOAA 1254 to a new region located on the east limb. The new region is displaying bright surges in H-alpha. It was the source of two B-class events. The largest was a B5.4 at 07/23/14:49 UT. Additional B-class events expected in the next 24 hour period. There is a slight chance of a C-class event if the region continues in growth phase. The position of the target on July 23 at 14:50 UT is: N19E89 (Solar X = -893", Solar Y = 305") 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. The target region was the source of B-class events. Additional B-class activity is possible today. The position of NOAA 1254 on July 22 at 15:30 UT is: S24W37 (Solar X = 520", Solar Y = -443") 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 remains low. The largest event was B8.3 produced by target region NOAA 1254 at 07/20/15:51 UT. 1254 lost sunspot area in the leading portion but gained penumbral area in the trailing portion. It currently has a C-type/beta sunspot group. NOAA located at N25E33 is also developing new flux in its trailing portion. Both target region 1254 and 1259 may produce a C-class event in the next 24 hour period. The position of NOAA 1254 on July 21 at 15:30 UT is: S22W26 (Solar X = 385", Solar Y = -420") 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 is maintaining a low level - only B-class events in the last 24 hour period. The target region (NOAA 1254) was the source of most of the B events with the largest a B7.2 at 07/20/10:00 UT. 1254 is slowly increasing sunspot area and count. The region has a D-type/beta sunspot group and is currently displaying a weak arch-type filament system with minor bright disk surges. B-class events probable with a slight chance of an isolated C-class event as well. The position of NOAA 1254 on July 20 10:30 UT is: S22W10 (Solar X = 152", Solar Y = -425") 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 low level. The target region produced two B-class events during the last period. NOAA regions 1254, 1257, and 1259 are all capable of producing an isolated C-class event. The target region will switch from NOAA 1257 now located on the west limb to NOAA 1254 located near disk center. 1254 was the source of two B-class events. The largest was a B7.1 at 07/19/11:27 UT. Additional B-class events probable with a slight chance of an isolated C-class event as well. The position of NOAA 1254 on July 19 at 15:30 UT is: S22E02 (Solar X = -030", Solar Y = -426") 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 remains at a low level. The largest x-ray event was a C1.0 event at 07/18/10:28 UT. Its source region was NOAA 1254 (S23E14). The target EFR, now numbered NOAA 1257, produced a B8.0 event at 07/17/19:26 UT. 1257 grew rapidly early in the period but is now in a stable phase. An isolated C-class event is still possible in the next 24 hour period. The position of NOAA 1257 on July 18 at 15:30 UT is: N19W65 (Solar X = 810", Solar Y = 276") 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 was very low during the last 24 hour period. NOAA 1254 was the source of the largest x-ray event since the last report (B6 at 17:05 UT). 1254 continues in slow decay phase. The target region will switch the an EFR that is in rapid growth phase. The EFR is displaying bright H-alpha plage with a strong arch-type filament system. Its sunspot group is currently a C-type/beta. An isolated C-class event is possible in the next 24 hour period if the EFR continues to develop. The position of the target region on July 17 at 13:45 UT is: N20W50 (Solar X = 682", Solar Y = 278") 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. NOAA 1250 is in decay phase. The target will switch to NOAA 1254. 1254 is currently a D-type/beta sunspot group. It has the potential to produce B-class events. No significant solar flare activity expected in the next 24 hour period. The position of NOAA 1254 on July 16 at 10:30 UT is: S22E43 (Solar X = -598", Solar Y = -402") 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 is very low. The target region, NOAA 1250, is slowly decaying. No significant events expected anytime soon.
