MM#009 Default HESSI Target
by Max Millennium Chief Observer 11 May '15

11 May '15

MM#009 Default HESSI Target Dear RHESSI Collaborators, Target region NOAA 2339 is mostly unchanged maintaining its very large F-type/beta-gamma sunspot group. The magnetic complexity is located within the trailing portion at N13E04. 2339 was the source of C-class activity in the past 24 hours. The most interesting event since the last massage was a filament eruption and flare located along the magnetic inversion line between NOAA regions 2342 and 2343. The eruption was associated with a C2.5 x-ray event at 04:09 UT. NOAA 2339 will continue to produce C-class activity with an M-class event possible in the next 24 hour period. A major flare is also possible but less likely today. The position of NOAA 2339 on May 11 at 15:35 UT is: N13W01 (Solar X = 016", Solar Y = 264") 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 10 May '15

10 May '15

Dear RHESSI Collaborators, The level of solar activity is low. NOAA region 12339 has displayed some initial signs of entering decay phase, decreasing in spot area while increasing in number of spots. The intermediate spots of NOAA 12339 have shown the beginnings of decay the most, but this region has maintained a beta-gamma/F-type sunspot group designation. 12339 has remained the most flare-productive region, being the source of 5 C-class events since yesterday’s message. The MM#003 Major Flare Watch will continue for a final 24 hours as this region retains the potential for another isolated flare above the M5 level. The position of NOAA 12339 on 10-May-2015 at 23:00 UT is: N12E11, ( -183”, 249” ) 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

Dear RHESSI Collaborators, Solar activity continues at a low level. NOAA 12339 has undergone further growth over the past 24 hours, increasing in both spot area and number of spots. 12339 has continued to maintain a beta-gamma/F-type sunspot group classification and is the most flare-productive region, being the source of 4 C-class events since yesterday’s message. The Major Flare Watch will continue for another 24 hours as the recent flux emergence indicates that this region retains the potential for another flare above the M5 level. The position of NOAA 12339 on 9-May-2015 at 21:30 UT is: N13E23, ( -365", 263" ) 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 continues to be low. NOAA region 12339 has grown further over the past 24 hours, increasing in both spot area and number of spots. This region has maintained a beta-gamma/F-type sunspot group classification. NOAA 12339 has produced 7 C-class events since yesterday’s message, including the largest flare of the period (a C5.5 on 8-May-2015 at 03:56 UT). The Major Flare Watch will continue for 24 hours as this region retains the potential for another flare above the M5 level. The position of NOAA 12339 on 8-May-2015 at 16:00 UT is: N13E38, ( -574”, 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.

MM#003 Major Flare Watch

Dear RHESSI Collaborators, Solar activity has returned to a low level. NOAA region 12339 has continued to produce low-level flaring activity after the X2.7 flare on 5-May-2015 at 22:05 UT. This region has now been the source of 5 C-class events since the MM#003 Major Flare Watch commenced yesterday, including the largest flare of the period (a C4.3 on 7-May-2015 at 09:54 UT). NOAA 12339 is classified as a beta-gamma/F-type sunspot group, appearing to have emerged new magnetic flux over the past 24 hours. The Major Flare Watch will continue for 24-48 hours as this region retains the potential for more flaring above the M5 level. The position of NOAA 12339 on 7-May-2015 at 16:00 UT is: N12E50, ( -716", 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.

Dear RHESSI Collaborators, Solar activity has increased significantly. The new region on the northeast limb was the source of an X2.7 flare at 22:05 UT yesterday and has been designated as NOAA 12339. The region appears to have a beta-gamma-delta/E-type configuration and is showing signs of negative polarity flux emergence within the positive core of the region. At this time we are implementing a Major Flare Watch campaign due to the increased probability of additional flaring greater than the M5 level. The position of NOAA 12339 on 6-May-2015 at 19:35 UT is: N12E58, ( -790", 228" ) 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. A new region that is rotating over the North East limb has been the source of two low M-class events (an M1.9 and an M1.2), but remains too close to the limb to accurately determine its magnetic classification. NOAA 12335 has also produced an M1.3 event in addition to the largest magnitude event since yesterday’s message (an M2.6 flare on 5-May-2015 at 17:12 UT). 12335 has continued to emerge new flux and is now classified as a beta-gamma/E-type sunspot group. Further C-class activity is expected in the next 24 hour period, with a good chance for additional low M-class flares. The position of NOAA 12335 on 5-May-2015 at 22:00 UT is: S15E12, ( -190", -188" ) 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 region 12335 continues to be the largest spotted region on the visible disk. This region has undergone minor flux emergence over the past 24 hours and is classified as a beta/D-type sunspot group, although it appears to exhibit magnetic polarity mixing in its intermediate portion (i.e. a beta-gamma configuration). NOAA 12335 has maintained flaring at the C-class level, producing 6 low C-class flares and the largest event in the previous 24 hours (a C8.0 on 4-May-2015 at 00:43 UT). Further C-class activity is expected in the next 24 hour period. The position of NOAA 12335 on 4-May-2015 at 18:00 UT is: S16E27, ( -418", -208" ) 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 levels. The target region NOAA 12335 was the source of 5 C1 and 4 high B-level events since the last message. There was a QS-filament eruption at ~16:30 UT yesterday across the southern hemisphere, which was associated with a two-ribbon flare and a halo CME. NOAA 12335 maintains its D-type/beta-gamma magnetic configuration, increasing its spot area and count. It continues to show mixed polarities in its intermediate portion. Low level activity is expected in the next 24 hours. The position of NOAA 12335 on May 3 at 15:35 UT is: S15E43 (Solar X = -628", Solar Y = ,-200") 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 been at very low levels for the past 24 hours with X-ray flux below the C-level. The target region NOAA 12335 is the only region with sunspots on the visible solar disk. 12335 has a D-type/beta-gamma magnetic configuration. It is showing some mixed polarities in its leading portion. C-class activity is likely in the next 24-48 hours. The position of NOAA 12335 on May 2 at 15:35 UT is: S15E54 (Solar X = -745", Solar Y = -208") 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.
