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

30 Nov '14

Dear RHESSI Collaborators, Solar activity is at a low level. NOAA region 12222 continues to be the largest group on the visible disk and emerged new magnetic flux over the previous 24 hours to grow in spot area and number of spots. NOAA 12222 remains classified as a beta-gamma/E-type sunspot group and produced four C-class events since yesterday’s message with the largest being a C3.8 flare on 29-Nov-2014 at 18:01 UT. More C-class activity is expected from this region over the next 24 hours, with a reasonable chance for an M-class event. The position of NOAA 12222 on 30-Nov-2014 at 19:00 UT is: S21E20, ( -307”, -364" ) 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. NOAA region 12222 has continued to grow in spot area and number of spots over the previous 24 hours by emerging new magnetic flux. This region is now classified as a beta-gamma/E-type sunspot group and produced four C-class events since the last message, including the largest flare of the period (a C6.7 on 29-Nov-2014 at 08:16 UT). More C-class activity is expected from this region in the following 24 hours, with a reasonable chance for an M-class event. The position of NOAA 12222 on 29-Nov-2014 at 11:00 UT is: S20E38, ( -565", -348" ) 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 low-to-moderate levels. NOAA region 12222 has grown in reported spot area and number of spots as it becomes more visible with rotating away from the South East limb. This region is now designated as a beta-gamma/D-type sunspot group, but there are still signs of a potential small delta spot embedded in the trailing penumbra of the primary leading spot. 12222 has continued to be the most flare productive region over the past 24 hours, producing three C-class flares (the largest being a C7.5 on 28-Nov-2014 at 00:29 UT). Further C-class activity is expected over the next 24 hours, with a good chance for a low-to-mid M-class event. The position of NOAA 12222 on 28-Nov-2014 at 12:30 UT is: S20E52, ( -724”, -345” ) 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 12217 appears to be in decay phase, decreasing in spot area and increasing in number of spots. This region produced no flare activity over the previous 24 hours. NOAA region 12222 has recently rotated over the South East limb and shows an increasingly complex configuration. This region is only classified as an alpha/H-type sunspot group, but realistically has at least a beta-gamma magnetic complexity with some indication of a potential delta (depending on the penumbral connections between the leading polarity spot and its immediate opposite polarity neighbouring spot). 12222 has been the source of eight C-class flares since the last message, including the largest flare of the period (a C8.2 on 27-Nov-2014 at 00:39 UT). Further C-class activity is expected over the following 24 hour period, with a good chance for a low-to-mid M-class event. The position of NOAA 12222 on 27-Nov-2014 at 13:00 UT is: S20E63, ( -815”, -343” ) 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 a low level. NOAA 12217 emerged more magnetic flux since yesterday’s message, increasing in number of spots, spot area and complexity. This region is classified as a beta-gamma/E-type sunspot group and was the source of the largest flare in the past 24 hours - a C2.9 on 26-Nov-2014 at 06:09 UT. More C-class activity is expected over the next 24 hours, with a small chance for an isolated low M-class event. The position of NOAA 12217 on 26-Nov-2014 at 15:00 UT is: S19E33, ( -500”, -337” ) 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 two largest regions on the visible disk (NOAA regions 12209 and 12216) showed signs of decay over the past 24 hours, while NOAA 12217 emerged new magnetic flux. NOAA 12217 remains classified as a simple beta/C-type sunspot group but displays a small amount of mixed polarity flux with no spots in its intermediate portion. This region was the only source of C-class flaring since yesterday’s message and also produced several H-alpha flares. More C-class activity is expected over the following 24 hour period, with a small chance for an isolated low M-class event. The position of NOAA 12217 on 25-Nov-2014 at 13:00 UT is: S19E46, ( -662”, -335” ) 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. Yesterday’s target is designated as NOAA 12217 after rotating further onto the disk. This region is classified as a simple beta/C-type sunspot group but has continued to produce C-class events since yesterday’s message, including the largest event of the past 24 hours (a C4.1 flare on 24-Nov-2014 at 10:50 UT). Further C-class activity is expected over the following 24 hours, with a small chance for a low M-class event. The position of NOAA 12217 on 24-Nov-2014 at 18:30 UT is: S19E58, ( -780”, -331” ) 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 the C-level. Both NOAA 12209 and 12216 have been relatively quiet since the last message. A new region on the southeast limb has produced several occulted, C2 flares over the past few hours, and shall be the new target region. The region is unnumbered and its configuration is uncertain, but increased activity is possible. The approximate position of the target region on 23-Nov-2014 at 16:35 UT is: S19E83, ( -913", -319" ) 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, There have been a number of C-level flares over the past 24 hours, the largest being a C8.1 event at 00:54 UT today from NOAA 12209. The current target region NOAA 12216 also produced some minor activity, and has increased in both size and complexity and is now classified as a beta-delta region. Chance of further increased activity over the next 24 hours. The position of NOAA 12216 on 22-Nov-2014 at 16:35 UT is: S14E44, ( -656", -258" ) 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 has remained steady around the C1 level since the last message. The target region in the southeast quadrant has now been designated NOAA 12216 and is classified as a beta/D-type region. The region has been quiescent since the C7.6 flare yesterday, but Ca XV maps show enhanced emission coming from the vicinity of the region. Possibility of isolated low-to-intermediate level events over the next 24 hours. The position of NOAA 12216 on 21-Nov-2014 at 12:35 UT is: S13E61, ( -829", -235" ) 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.
