MM#009 Default Target
by Max Millennium Chief Observer 30 May '22

30 May '22

Dear Collaborators, The largest event in the past 24 hours was a B6.3 flare produced by NOAA 13024 (S33E03) at 05/30 15:01 UT. The target region NOAA 13025 was the source of three low B-class flares. 13025 has been designated as a beta/ D-type configuration with significantly increasing the sunspot area. Further B-class activities are expected with a chance of a low C-class flare when the target region rotates to the west limb. The position of NOAA 13025 on May 31 at 03:30 UT is: N27W65 (765", 435") 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 has been numbered as NOAA 13025 with a beta/C-type configuration. It has produced four B-class flares since the last message. Note that there were two C-class flares (C1.5 and C1.4) produced by the plage region NOAA 13019 and also NOAA 13023 in the past few hours. The target region 13025 is emerging negative fluxes in its leading positive polarity. More B-class activities are expected with a chance of C-class flares in the next 24 hours. The position of NOAA 13025 on May 30 at 03:30 UT is: N28W55 (685", 452") 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 3023 (S13E16, H-type/alpha) was stable and quiescent in the past 24 hours. The target will switch to an EFR that is currently displaying a B-type/beta sunspot group. This region was the source of a B7.1 event at 05/29/17:05. A C-class event is possible in the next 24 hour period. The position of the target region on May 29 at 14:00 UT is: N27W45 (Solar X = 598", Solar Y = 441") 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 3014 is now located well beyond the northwestern limb but was the source of a few limb occulted C-class events since the last message. The regions currently located on the visible solar disk all have simple alpha magnetic classifications. The default target will switch to NOAA 3023. (H-type/alpha). No significant solar flare activity expected in the next 24 hour period. The position of NOAA 3023 on May 28 at 15:30 UT is: S14E29 (Solar X = -446", Solar Y = -214") 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 3014 (E-type/beta) has now almost completed west limb passage. 3014 was the source of a couple of minor C-class events since the last message. C-class events are possible with only a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 3014 on May 27 at 15:30 UT is: N22W91 (Solar X = 877", Solar Y = 354") 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 3014 (E-type/beta) continues in decay phase and only produced minor C-class events since the last message. C-class activity likely with only a slight chance of an isolated M-class event in the next 24 hour period. The largest event yesterday was an M1.3 event at 05/25/18:24 UT. The event was trigged by an eruptive filament located along the main magnetic inversion line of spotless NOAA 3016 (S19W41). The position of NOAA 3014 on May 26 at 15:30 UT is: N22W83 (Solar X = 871", Solar Y = 357") 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 3014 continues in decay phase. Its large E-type sunspot group's magnetic delta configuration has significantly weakened again since the last message and will likely disappear in the next 24 hours. 3014 was mostly quiescent producing only a few minor C-class events since the last message. At this time we will terminate the MFW but keep 3014 as the preferred default target. C-class events likely with a slight chance of an isolated M-class event in the next 24 hour period. The position of NOAA 3014 on May 25 at 10:45 UT is: N23W67 (Solar X = 804", Solar Y = 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.

MM#003 Major Flare Watch

24 May '22

MM#003 Major Flare Watch Dear Collaborators, Target region NOAA 3014 (E-type/beta-delta) is slowly decaying and produced only minor C-class events since the last message. The magnetic delta configuration has significantly weakened but 3014 is still a large and complex region. An event =>M5 remains a slight possibility in the next 24 hour period. Note that a region located just beyond the southeastern limb (S11) was the source of a limb occulted C3.6 event at 05/24/06:37 UT. The position of NOAA 3014 on May 24 at 14:45 UT is: N23W56 (Solar X = 725", Solar Y = 384") 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

23 May '22

MM#003 Major Flare Watch Dear Collaborators, Target region NOAA 3014 (E-type/beta-gamma-delta) is slowly decaying and only produced minor C-class events since the last message. Its magnetic delta configuration is weakening but the region is maintaining its large somewhat complex sunspot group. New flux emergence in 3014 is needed to increase the probability of larger events. An isolated >=M event is still possible in the next 24 hour period. The position of NOAA 3014 on May 23 at 10:45 UT is: N23W42 (Solar X = 586"< Solar Y = 391") 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 22 May '22

22 May '22

Dear Collaborators, Solar activity continues at the low C-level with NOAA 13014 remaining mostly quiescent since the last message. The region has shown signs of decay but retains its delta configuration due to mixed polarity within the trailing edge of the eastern sunspot. Major Flare Watch shall remain in effect for a further 24 hours due to the possibility of a >M5 flare. The position of NOAA 13014 on 22-May-2022 at 07:30 UT is: N22W28, ( 413", 381" ) 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.
