MM#009 Default HESSI Target
by Max Millennium Chief Observer 12 Jan '14

12 Jan '14

Dear RHESSI Collaborators, The level of solar activity is low. NOAA region 11944 continues to decay, remaining classified as a beta-gamma-delta/F-type sunspot group. This region has maintained flare productivity over the past 24 hours, being the source of 5 C-class flares (the largest being a C6.0 flare on 11-Jan-2014 at 23:57 UT). Further C-class activity is expected over the following 24 hours, with a chance for a flare >M5 from NOAA 11944 still remaining. The position of NOAA 11944 on 12-Jan-2014 at 14:30 UT is: S10W62, ( 850", -135" ) 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. NOAA 11944 has continued to decay over the past 24 hours, decreasing in both spot area and number of spots. This region has maintained a beta-gamma-delta/F-type sunspot group classification, while the region's decay has further weakened its delta spot configuration. NOAA 11944 has returned to producing flare activity, being the source of four C-class flares in the past 24 hours (the largest being a C6.5 on 11-Jan-2014 at 13:00 UT). More C-class activity is expected over the next 24 hours, with a chance for a flare >M5 still possible from 11944. The position of NOAA 11944 on 11-Jan-2014 at 14:30 UT is: S09W51, ( 751", -108" ) 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 region 11944 has shown signs of decay, decreasing somewhat in spot area and significantly in number of spots. This region remains the largest and most complex region on the visible disk with displaying a beta-gamma-delta/F-type sunspot group classification, although the delta spot strength has weakened. NOAA 11944 produced only one low C-class flare since the last message, so the MM#003 Major Flare Watch ceases at this time. Further C-class activity is expected over the next 24 hours, with a chance for a flare above the M5 level still possible due to past flare behaviour of 11944. The position of NOAA 11944 on 10-Jan-2014 at 19:30 UT is: S09W39, ( 606", -99" ) 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#003 Major Flare Watch
by Max Millennium Chief Observer 09 Jan '14

09 Jan '14

Dear RHESSI Collaborators, Solar activity is at a moderate level. NOAA 11944 remains the largest and most complex region on disk, displaying a beta-gamma-delta/F-type sunspot group classification. This region has maintained both sunspot area and number of spots since yesterday's message, but only produced low C-class flares over the past 24 hours. The MM003 Major Flare Watch will continue for another 24 hours, as 11944 retains the potential for additional flaring above the M5 level. The position of NOAA 11944 on 9-Jan-2014 at 13:00 UT is: S09W24, ( 396", -92" ) 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#003 Major Flare Watch
by Max Millennium Chief Observer 08 Jan '14

08 Jan '14

Dear RHESSI Collaborators, The level of solar activity is high. NOAA 11944 has grown in spot area over the past 24 hours, while maintaining number of spots and a beta-gamma-delta/F-type sunspot group classification. Since the MM#003 Major Flare Watch was initiated yesterday, NOAA 11944 was the source of an X1.2 flare on 7-Jan-2014 at 18:04 UT. The Major Flare Watch will continue for at least another 24 hours, as 11944 retains the potential for additional flaring above the M5 level. The position of NOAA 11944 on 8-Jan-2014 at 12:30 UT is: S09W10, ( 167", -89" ) 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#003 Major Flare Watch

07 Jan '14

Dear RHESSI Collaborators, Solar activity is at a moderate level. NOAA region 11944 continues to be the largest and most complex region on the visible disk, displaying a beta-gamma-delta/F-type sunspot group configuration. This region has maintained both spot area and number of spots over the past 24 hours, producing low C-class flares and an M7.2 on 7-Jan-2014 at 10:07 UT. At this time we are implementing a MM#003 Major Flare Watch, as 11944 has produced a flare above M5 and retains the capacity to produce further major flares. The position of NOAA 11944 on 7-Jan-2014 at 12:30 UT is: S09E04, ( -69", -90" ) 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 region 11944 has maintained a beta-gamma-delta/F-type sunspot group classification over the past 24 hours. This region has also maintained spot area coverage through several smaller spots coalescing into larger, more mature spots. NOAA 11944 produced 3 C-class flares since yesterday's message (the largest being a C7.1 on 6-Jan-2014 at 00:08 UT). However, the X-ray background and flare magnitude/frequency is generally decreasing. Further C-class activity is expected over the next 24 hours, with a reasonable chance for a mid M-class flare and a small chance for an X-class flare. The position of NOAA 11944 on 6-Jan-2014 at 16:00 UT is: S09E16, ( -269", -94" ) 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 largest event in the past 24 hours was an M4.0 at 01/04/19:46 UT. The primary location of the flare was in the trailing spotless plage of NOAA 1943 which is adjacent to the leading opposite polarity portion of NOAA 1944. There was likely an interaction between the two regions. 1944 also brightened during the event. 1944 increased its magnetic complexity adding a delta configuration located in the trailing sunspots. The region is now classified F-type/beta-gamma-delta. M-class activity likely with the chance of an event =/>M5 in the next 24 hours. The position of NOAA 1944 on January 05 at 16:30 UT is: S08E28 (Solar X = -455", Solar Y = -083") 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, NOAA 1944 was the source of numerous C-class events and two minor M-class events in the past 24 hours. The largest event was an M1.3 at 01/04/10:25 UT. 1944 is currently one of the largest regions of Solar Cycle 24. The large leader sunspot is significantly decayed in magnetic complexity but mixed polarities are located within the intermediate and trailing portions of the F-type/beta-gamma sunspot group. Additional low-level M-class activity expected with the chance of an event =/>M5 in the next 24 hours. The position of NOAA 1944 on January 04 at 16:30 UT is: S09E43 (Solar X = -659", Solar Y = -110") 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, Target region NOAA 1944 was the source of numerous C-class events and two low-level M-class events in the past 24 hours. 1944 has decayed somewhat losing its magnetic delta configuration that was located within the northern portion of the large leading sunspot but 1944 remains a large F-type/beta-gamma region. M-class events likely in the next 24 hours. The position of NOAA 1944 on January 03 at 12:30 UT is: S08E57 (Solar X = -812", Solar Y = -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.
