MM#003 Major Flare Watch
by Max Millennium Chief Observer 31 Oct '15

31 Oct '15

Dear RHESSI Collaborators, The target region NOAA 12443 has produced several C-class flares since the last message, including a C7.8 at 19:57 UT today. The region is now classified as a beta-gamma-delta/E-type region with a total area of over 500uH. It has continued to grow in size and complexity, and there is currently a negative polarity sunspot emerging within the positive trailing group. The region also appears bright in H-alpha emission. At this time we are implementing a Major Flare Watch campaign due to the increased possibility of an M5 flare or greater over the next 24-48 hours. The position of NOAA 12443 on 31-Oct-2015 at 15:35 UT is: N06E47, ( -704", 49" ) 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 activity has increased significantly since the last message. The new region on the eastern limb has now been designated as NOAA 12443. The region has produced several mid-C-level flares including a C5.5 at 08:21 UT today. Its trailing spot has a very complex magnetic configuration and is undergoing rapid negative flux emergence within the surrounding positive plage. Sustained C-class activity is likely with chance for low M-level events. The position of NOAA 12443 on 30-Oct-2015 at 12:35 UT is: N05E59, ( -826", 44" ) 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 appears to be on the increase due to the appearance of a new active region on the eastern limb. The region is currently unnumbered and its magnetic configuration is uncertain, but it has produced a flurry of low C-class flares since the last message and shall therefore be the new target region. Further C-level activity expected over the next 24 hours. The approximate position of the target region on 29-Oct-2015 at 12:35 UT is: N09E79, ( -938", 136" ) 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 the low C-level with flares emanating from multiple active regions over the past 24 hours. NOAA 12436 has continued to decay as it approaches the western limb but shall remain the target region. Chance for further isolated low-level events. The position of NOAA 12436 on 28-Oct-2015 at 15:35 UT is: N08W70, ( 899", 106" ) 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 low levels aside from an long-duration C3.2 flare at 13:05 UT today from NOAA 12435 as it transits the western limb. NOAA 12436 was the source of a C1.0 flare at 05:05 UT today and has shown significant signs of decay over the past 24 hours. NOAA 12436 shall remain the target region although only isolated low-level events are expected at this time. The position of NOAA 12436 on 27-Oct-2015 at 15:35 UT is: N09W55, ( 782", 104" ) 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 C2.1 flare from NOAA 12437. A new region has begun to emerge in the northern hemisphere along the central meridian but has so far been quiescent. NOAA 12436 remains largely unchanged and shall be the target region for a further 24 hours. B-level activity possible with chance for an isolated C-class flare. The position of NOAA 12437 on 26-Oct-2015 at 15:35 UT is: N09W43, ( 652", 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 very low. Over the previous 24 hours, decaying NOAA region 12436 has emerged small leading-polarity spots close to the cluster of trailing polarity spots. This region remains designated as a beta/E-type sunspot group, but may now be exhibiting a beta-gamma magnetic classification. NOAA 12436 has not produced any flares at or above C-class since yesterday's message, but remains the most likely region to flare. C-class events are possible over the next 24 hours. The position of NOAA 12436 on 25-Oct-2015 at 14:00 UT is: N09W27, ( 431", 76" ) 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 very low level. NOAA 12436 has shown signs of decay over the past 24 hours, decreasing in number of spots and area as well as simplifying further in magnetic complexity. NOAA 12436 is classified as a beta-gamma/E-type sunspot group and has not produced any flaring activity at or above C-class since yesterday's message. C-class flares are probable over the next 24 hours. The position of NOAA 12436 on 24-Oct-2015 at 18:00 UT is: N09W16, ( 263", 69" ) 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 12436 has remained stable over the past 24 hours in terms of number of spots and area. This region has simplified in magnetic complexity and is classed as a beta-gamma/E-type sunspot group, but recent images indicate that it might have simplified further to a beta magnetic class. None of the regions on disk produced activity at or above C-class since the last message. C-class flares are probable in the following 24 hours. The position of NOAA 12436 on 23-Oct-2015 at 12:30 UT is: N08W01, ( 16", 47" ) 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 12436 has grown slightly over the past 24 hours, increasing marginally in sunspot area and number of spots. This region has remained classified as a beta-delta/E-type sunspot group, but recent magnetograms indicate it may have lost its small delta spot. 12436 again produced the largest magnitude flare since the last message, a C7.7 on 21-Oct-2015 at 17:48 UT. More C-class activity is expected in the next 24-hour period, with a small chance for a low M-class flare. The position of NOAA 12436 on 22-Oct-2015 at 11:30 UT is: N08E10, ( -160", 47" ) 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.
