MM#009 Default Target

10 Apr '22

MM#009 Default Target Dear Collaborators, Target regions NOAA 2978/2981 have almost completed west limb passage. The regions were the source of two C-class events since the last message. 2978 produced a C1.1 at 04/09/02:41 UT and 2981 produced a C4.9 at 04/10/02:41 UT. There is still a chance of another C-class event before the regions rotate too far beyond the southwestern limb. The position of NOAA 2978/2981 on April 10 at 14:00 UT is: S22W89 (Solar X = 888", Solar Y = -355") 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 2978 (S19W83, C-type/beta) is mostly unchanged and was quiescent since the last message. Its companion region NOAA 2981 (S23W83, C-type/beta) was the source of a few C-class events. The largest was a C4.7 at 04/09/11:24 UT. The flare was located in the southern portion of 2978 and the northern portion of 2981 at S21W87. The target position today will include both regions. Another C-class event is possible in the next 24 hour period. The position of NOAA 2978/2981 on April 09 at 14:00 UT is: S22W84 (Solar X = 884", Solar Y = -347") 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 2978 (C-type/beta) has significantly decayed, losing most of its intermediate and trailing sunspots. 2978 was the source of a C2.4 event at 04/08/15:14 UT. Another C-class event is possible in the next 24 hours. There is an EFR developing within the leading portion of decaying NOAA 2983. The EFR produced a C1.0 event at 04/08/11:21 UT. The position of NOAA 2978 on April 08 at 14:00 UT is: S19W70 (Solar X = 853", Solar Y = -278") 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 2978 continues to decay along with its companion region NOAA 2981 (S22W55). Both regions were the source of minor B-class events since the last message. A C-class event is still possible in the next 24 hour period. A large filament located in the southeastern quadrant (S35E10) became active/eruptive and disappeared by 4/7/06:00 UT. The position of NOAA 2978 on April 07 at 14:00 UT is: S19W57 (Solar X = 762", Solar Y = -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#009 Default Target Dear Collaborators, Target region NOAA 2978 (E-type/beta) is slowly decaying especially within its intermediate and trailing portions. 2978 was the source of a minor C1.3 at 04/06/04:20 UT. NOAA 2981 located just south of 2978 (S25W43, C-type/beta)) produced a C1.3 event at 04/06/06:23 UT. 2981 is also decaying. The largest event since the last message was a C3.1 at 04/06/10:27 UT. The event was limb occulted at N14 degrees. C-class events possible in the next 24 hour period. The position of NOAA 2978 on April 06 at 14:00 UT is: S19W44 (Solar X =632", Solar Y = -240") 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, The target NOAA 2975/2984 was the source of limb occulted C-class activity since the last message. The largest events were a C1.4 at 04/04/23:29 UT produced by 2975 and a C1.5 at 04/05/03:16 produced by 2984. The target regions are now well beyond the northwestern limb. The new target will be NOAA 2978. C-class events are possible in the next 24 hour period. The position of NOAA 2978 on April 05 at 14:00 UT is: S18W30 (Solar X = 458", Solar Y = -209") 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, The Major Flare Watch target region NOAA 2975 has almost completed west limb passage. At this time we will suspend the Major Flare Watch. NOAA regions 2975, 2976 and 2984 were the source of several C-class events since the last message. The largest was a C6.4 at 04/03/13:09 UT produced by 2976 (N17W74). The target will continue to monitor the three northwestern limb regions for the next 24 hour period. C-class activity likely with an isolated M-class event still possible. The position of NOAA 2975/2984 on April 04 at 14:00 UT is: N15W88 (Solar X = 926", Solar Y = 250") 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 02 Apr '22

02 Apr '22

Dear Collaborators, The Major Flare Watch region NOAA 12975 was the source of an M4.3 flare at 04/02/17:34 UT. An M3.9 flare (at 04/02/12:56 UT) was also produced by a newly numbered region NOAA 12984 (N12W71, beta/D-type), just nearby 12975. Now 12975 has been classified as a beta-delta/E-type region and is rotating over the west limb. We will continue the Major Flare Watch on NOAA 12975 (and also 12984) for another 24 hours. A major flare or a low M-class flare is still likely in the next 24 hours. The position of NOAA 12975 on April 3 at 03:30 UT is: N15W80 (913", 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

02 Apr '22

Dear Collaborators, The Major Flare Watch region NOAA 12975 produced an M2.9 flare at /04/02 02:39 UT and also a few C-class flares in the past 24 hours. Another two regions, NOAA 12978 (S18E10, beta-gamma/E-type) and 12981 (S26E14, beta-gamma/D-type) also produced numerous C-class flares. We will continue the Major Flare Watch on NOAA 12975 for another 24 hours. Now the region has been classified as a beta/E-type configuration. There is still a chance for a major flare before it rotates over the west limb. The position of NOAA 12975 on April 2 at 07:30 UT is: N13W70 (879", 250") 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

01 Apr '22

Dear Collaborators, The Major Flare Watch region NOAA 12975 produced an M9.6 flare at 03/31/18:17 UT plus three low C-class flares in the past 24 hours. Another two regions, NOAA 12981 (S26E27, beta/D-type) and 12978 (S18E24, beta-gamma/E-type) also produced numerous C-class flares. We will continue the Major Flare Watch on NOAA 12975 today. It retains a beta-gamma-delta/D-type configuration when rotating to the west limb. Another major flare is still likely in the following two days. The position of NOAA 12975 on April 1 at 07:30 UT is: N13W56 (777", 274") 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.
