MM#009 Default HESSI Target
by Max Millennium Chief Observer 30 Sep '14

30 Sep '14

Dear RHESSI Collaborators, The level of solar activity is low. Since the previous message, NOAA 12173 was responsible for low C-class activity but shows signs of further decay. NOAA 12177 has ceased emerging significant new flux but maintains a weak mixed polarity spot in its intermediate portion. Low C-class events are possible with a chance for a high C-class flare. The position of NOAA 12177 on 30-Sep-2014 18:15 UT is: N11E21, ( -337", 79" ) 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. Since the previous message, NOAA 12173 was responsible for C-class activity and the largest event, a M1.0 flare on 28-Sep-2014 at 17:33 UT. However, the region continues to decay. NOAA 12175 maintains its strong delta configuration, but its flux emergence appears to have subsided and no significant activity was released. On the other hand, NOAA 12177 has emerged new flux in its following and intermediate portion, resulting in a mixed polarity spot. The region has was responsible for moderate C-class activity, so far. Further C-class events are likely with a chance for an M-class flare. The position of NOAA 12177 on 29-Sep-2014 18:30 UT is: N12E33, ( -509",105" ) 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. Since the previous message, NOAA 12173 was responsible for an M5.1 flare on 28-Sep-2014 at 2:58 UT. However, the region does not show a strong polarity separation line or further substantial flux emergence. On the other hand, NOAA 12175 is rapid emerging flux in the following portion, and its delta spot has strengthened. High C-class activity is expected, with a chance for an M-class event. The position of NOAA 12175 on 28-Sep-2014 16:40 UT is: N15W45, ( 655",168" ) 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 to moderate. Since the previous message, yesterday's target (NOAA 12172) released several high C-class events, including a C8.7 flare on 26-Sep-2014 at 05:43 UT. New flux emergence is evident to the SW of its leading portion. The region does not show a strong polarity separation line, but exhibits a gamma configuration. On the other hand, NOAA 12172 (responsible for moderate C-class activity, so far) has emerged rapidly since the previous message and exhibits a strong shearing delta configuration, evidenced by the rapidly moving positive sunspot. High C-class activity is expected, with a chance for an M-class event. The position of NOAA 12175 on 26-Sep-2014 19:15 UT is: N15W23, ( 356", 144" ) 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. A new region currently rotating over the East limb was responsible for C-class activity since the previous message. Yesterday's target has not released further significant activity, but shows some evidence for flux emergence in its intermediate portion. Further C-class activity is expected, with a chance for another M-class event. The position of NOAA 12172 on 25-Sep-2014 18:00 UT is: S10E14, ( -230", -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.

Dear RHESSI Collaborators, The level of solar activity is low to moderate. A new emerging region is visible near disk center in the northern hemisphere, but has not yet produced significant activity. Since the previous message, yesterday's target (12172) was responsible for moderate C-class activity and an M2.3 flare on 23-Sep-2014 at 23:26 UT. There is evidence for further flux emergence in the intermediate portion of the region and a minor mixed polarity spot. Moderate C-class activity is expected, with a chance for further M-class event. The position of NOAA 12172 on 25-Sep-2014 4:45 UT is: S24E10, ( -346", -269" ) 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 (12172) has continued to release low C-class activity. There is some evidence for flux emergence in the intermediate portion of the region. Further low C-class activity is expected, with a chance for a moderate C-class flare. The position of NOAA 12172 on 23-Sep-2014 20:45 UT is: S11E39, ( -586", -271" ) 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 (12172) has continued to release low C-class activity. There is some evidence for flux emergence within the leading portion of the region. Further low C-class activity is expected, with a chance for a moderate C-class flare. The position of NOAA 12172 on 22-Sep-2014 23:40 UT is: S11E50, ( -720", -256" ) 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 low levels. The largest event since the last message was a C5.2 flare from NOAA 12166 at 11:31 UT today. A large sunspot group, designated NOAA 12172, has rotated onto the southeast limb and shall be the new target region. It has produced several low C-class flares over the past 24 hours and appears to have a beta-gamma configuration. Further low-level activity expected. The position of NOAA 12172 on 21-Sep-2014 at 15:35 UT is: S09E66, ( -863", -195" ) 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 low levels. NOAA 12169 has decayed significantly since the last message. NOAA 12171, a new region on the southeast limb, was the source of a C3.3 flare at 17:27 UT yesterday and shall be the new target region. It has a simple beta/D-type configuration and may produce additional isolated low level events over the next 24 hours. The position of NOAA 12171 on 20-Sep-2014 at 11:35 UT is: S09E58, ( -801", -210" ) 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.
