MM#009 Default Target
by Max Millennium Chief Observer 25 Sep '24

25 Sep '24

Dear Collaborators, Solar activity has dropped to a low level. The target region NOAA 13835 only produced a C2.4 flare at 14:01 UT yesterday. However, 13835 has again experienced the emergence of new magnetic fluxes in its intermediate portion since the last message, remaining a beta/D-type sunspot group. 13835 shall continue as the target. In addition, NOAA 13833 (N22W60, beta/C-type), NOAA 13828 (S11W41, alpha/H-type) and NOAA 13836 (S10E52, beta-gamma/D-type) also produced a few low-C flares, with the largest two being a C4.0 at 07:27 UT and a C3.7 at 10:07 UT today from 13836. Additional C-class activities are expected in the next 24 hours. The position of NOAA 13835 on 25-Sep-2024 at 11:30 UT is: S22E31 (-458", -449") 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 has returned to a moderate level. The largest event was an M1.4 flare at 14:23 UT yesterday from NOAA 13836 (S12E65, beta-gamma/D-type). A spotless region (S16W21) near NOAA 13828 also produced a C6.9 flare at 11:29 UT today. The target region NOAA 13835 was the source of a C6.5 flare at 03:33 UT today. This region retains its beta/D-type magnetic configuration and it continues to emerge new spots. Today the target region should remain with NOAA 13835. Further C-class activities are expected, with a chance of another low-M flare in the coming 24 hours. The position of NOAA 13835 on 24-Sep-2024 at 11:30 UT is: S25E42 (-581", -480") 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 has been at a moderate-to-low level. The largest event since the last message was an M3.8 flare at 21:12 UT on 22-Sep-2024 from NOAA 13835. This region emerged yesterday and has been classified as a beta/D-type sunspot group. 13835 shall become the new target. Yesterday’s target NOAA 13831 only produced a C3.7 flare at 13:18 UT on 22-Sep-2024. Besides, the other three low-C flares are produced by two active regions (NOAA 13828 and 13825) and an unnumbered region from the South East limb (S16E87). More C-class flares are expected, with M-class activity likely in the following 24 hours. The position of NOAA 13835 on 23-Sep-2024 at 11:30 UT is: S22E56 (-736", -416") 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 continues at a very low level. The target region NOAA 13831 was the source of three low C-class flares (all flares during the period recorded by GOES), with the largest one being a C4.5 at 20:37 UT on September 21. 13831 retains a beta/D-type configuration. Further C-class activities are expected in the next 24 hours. The position of NOAA 13831 on September 22 at 11:30 UT is: N12W30 (469", 98") 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 continues at a very low level. The largest event during the period was a C3.1 flare produced by NOAA 13831. 13831 also produced a C1.7 flare. Today the target will switch to 13831 that has developed to a beta/D-type region. Note that another region of NOAA 13834 also produced two low C-class flares. Yesterday's target NOAA 13825 has been flare quiet since the last message. Additional C-class flares are expected in the next 24 hours. The position of NOAA 13831 on September 21 at 07:30 UT is: N12W13 (211", 85") 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 continues at a very low level. The largest event since the last message was a C2.6 flare at 15:17 UT on September 19 produced by the target region NOAA 13825. 13825 retains a beta-gamma-delta/E-type configuration but increases in the spot area and number of spots. Please note that another region NOAA 13824 (S04W85, beta/E-type) was the source of five C1/C2 flares in the period, which is rotating over the west limb. Only C-class activities are expected in the next 24 hours. The position of NOAA 13825 on September 20 at 03:30 UT is: S16W23 (360", -367") 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 was at a very low level. The largest events since the last message were two C3.0 flares produced by the target region NOAA 13825 and NOAA 13824 (S04W73, beta-gamma/E-type). The target 13825 has been designated as a beta-gamma-delta/E-type region, which shows some flux emergence in its leading portion. C-class activities are expected with some chance of an isolated low M-class flare in the next 24-hour period. The position of NOAA 13825 on September 19 at 07:30 UT is: S15W11 (176", -358") 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 continues at a very low level. The largest event in the past 24 hours was a C4.1 flare at 09/18/03:33 UT produced by NOAA 13828 (S13E57, alpha/H-type). 13828 also produced another two low C-class flares. The target region NOAA 13825 was the source of two low C-class flares (C2.4 and C1.6) in the period, which retains a beta-gamma/E-type configuration. At this time, we are ending the Major Flare Watch campaign. Further C-class activities are expected with a small chance of an M-class flare in the next 24 hours. The position of NOAA 13825 on September 18 at 07:30 UT is: S15E02 (-32", -361") 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

17 Sep '24

Dear Collaborators, Solar activity continues at a low level. The largest event since the last message was a C9.6 flare at 09/16/23:29 UT produced by the target region NOAA 13825. 13825 retains a beta-gamma/E-type configuration but increases the sunspot area and number of spots slightly. New magnetic flux is emerging again especially in the leading portion of sunspots. Today we will continue the Major Flare Watch campaign on this region for one more day. Low M-class activity is likely with some chance of a flare above M5 in the next 24 hours. The position of NOAA 13825 on September 17 at 07:30 UT is: S16E16 (-253", -372") 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 16 Sep '24

16 Sep '24

Dear Collaborators, Solar activity has been at a low level since the last message. The largest event during the period was a C6.0 flare at 01:21 UT today produced by NOAA 13824 (S04W35, beta-gamma/C-type). The target region NOAA 13825 only produced four C-class flares with the largest one being a C5.0 at 13:30 UT today. 13825 has been designated as a beta-gamma/E-type region with decreasing the sunspot area and number of spots significantly. The Major Flare Watch campaign will continue for a further 24 hours. C-class activities are expected with a small chance of a major flare in the next 24 hours. The position of NOAA 13825 on September 16 at 15:30 UT is: S15E26 (-405", -349") 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.
