MM#003 Major Flare Watch
by Max Millennium Chief Observer 30 Nov '20

30 Nov '20

MM#003 Major Flare Watch Dear Collaborators, The target region produced a couple of minor limb occulted B-class events since the last message. A single round trailing polarity sunspot which is most likely the return of old NOAA 2781 has completed east limb passage at S20 degrees. The long duration M4.4 event yesterday was the strongest flare event of Cycle 25. There is a chance of another M-class event in the next 48 hours. The approximate position of the target on Nov. 30 at 09:30 UT is: S24E89 (Solar X = -889", Solar Y = -396") 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 Collaborators, At this time we are implementing Max Millennium coordinated observing plan #003 (Region Likely To Produce A Major Flare). A region located beyond the southeastern limb was the source of a limb occulted M4.4 event at 11/29/13:11 UT. The region is located in the vicinity of the return of old NOAA 2781. A well developed system of flare loop-type prominences is currently visible on the southeastern limb. Another M-class event is possible in the next 48 hours. The approximate position of the target on Nov. 29 at 13:15 UT is: S23E89 (Solar X = -896, Solar Y = -380") 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 Target Dear Collaborators, Target region 2786 has decayed somewhat since the last message but its sunspot group is still classified as an F-type/beta-gamma group. 2786 was the source of several minor B- and C-class events in the past 24 hours. The largest was a C2.9 at 11/28/13:35 UT. B- and C-class events likely with the chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2786 on November 28 at 15:00 UT is: S17E20 (Solar X =-320", Solar Y =-303") 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 Target Dear Collaborators, Target region NOAA 2786 produced several minor B- and C-class events since the last message. The largest was a C3.8 at 11/26/12:53 UT. The large leader sunspot's penumbra in its F-type/beta-gamma sunspot group has some opposite polarity satellite spots surrounding it. B- and C-class events expected with the chance of an isolated M-class event in the next 24 hour period. The position of NOAA 2786 on November 27 at 15:00 UT is: S17E34 (Solar X = -522", Solar Y = -303") 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 Collaborators, The target region NOAA 12786 has continued to produce B- and C-level activity since the last message, including a C3.8 flare at 12:42 UT today. The region retains its beta configuration but now has a sunspot area of 1000uH. The dominant leader spot appears stable but flux emergence continues in the trailing portion. Further low-to-intermediate level activity expected over the next 24 hours, with continued possibility of an M-class flare. The position of NOAA 12786 on 26-Nov-2020 at 12:30 UT is: S17E46, ( -670", -300" ) 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 Target Dear Collaborators, Target region NOAA 2786 was the source of numerous B-class events and an isolated C3.4 event at 11/25/04:02 UT. The region has completed east limb passage revealing a few trailing sunspots with rudimentary penumbra. Its current sunspot group classification is an elongated C-type/beta. The longitudinal extent of the sunspot group exceeds 15 degrees. B- and C-class events probable with an isolated M-class event possible in the next 24 hour period. The position of NOAA 2786 on November 25 at 15:00 UT is: S17E60 (Solar X = -807", Solar Y = -297") 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 Target

MM#009 Default Target Dear Collaborators, NOAA 2785 (S23E58, X=-761", Y=-394" at 15:00 UT) was the source of a C4.3 event at 11/23/23:37 UT. The flare was associated with the eruption of a filament located along the region's main magnetic inversion line. 2785 is maintaining it's simple H-type/alpha sunspot classification. A trailing sunspot in target region NOAA 2786 has rotated onto the visible disk but the region is still too close to the limb to ascertain its magnetic complexity. A few bright and dark surges have been visible again today. If possible, include the intermediate and trailing portion of 2785 along with 2786 within the F-O-V. C-class events probable with an isolated M-class event possible in the next 24 hour period. The position of NOAA 2786 on November 24 at 15:00 UT is: S17E73 (Solar X = -890", Solar Y = -292") 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 Target Dear Collaborators, Target region now numbered NOAA 2785 produced numerous B-class events and a C3.3 event at 11/23/17:31 UT. 2785 is mostly unchanged, maintaining its H-type/alpha sunspot group. A large leader sunspot has passed over the southeastern limb just northeast of 2785. The region has been numbered 2786 by NOAA. It is currently displaying many bright limb surges. 2786 was the source of a limb occulted C1.2 event at 11/22/23:56 UT. The target will switch to 2786. If possible, include 2785 (S23E70, X= -842", Y= -390" at 15:00 UT) in the F-O-V. C-class events probable with the chance of an isolated M-class event in the next 24 hour period. New flux emerged yesterday within the trailing portion of NOAA 2783 at S20E03. Its sunspots have developed into a C-type/beta group. The position of NOAA 2786 on November 23 at 15:00 UT is: S18E85 (Solar X = -921", Solar Y = -303") 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 Collaborators, Solar activity is increasing due to the appearance of the new active region currently behind the southeast limb. It has continued to produce B-level activity since the last message, as well as two occulted C1.3 flares today. Its magnetic configuration is still unclear at this time but it shall remain the target region for the next 24 hours with low-to-intermediate level activity likely. The approximate position of the target region on 22-Nov-2020 at 16:30 UT is: S22E87, ( -899", -365" ) 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 Collaborators, The level of solar activity is low. NOAA region 12783 has remained stable in terms of its number of spots and spot area since the last message. This region continues to be classified as an alpha/H-type sunspot group and has produced two B-class flares over the past 24 hours. A new region that is still located over the South East limb has produced multiple B-class flares and the largest event of the period - an occulted C1.0 flare on 21-Nov-2020 at 18:10 UT. This limb region will become the new target. Further B-class activity is expected in the following 24-hour period, with low C-class activity also likely. The approximate position of this region on 21-Nov-2020 at 18:00 UT is: S23E90 , ( -894", -379" ) 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.
