MM#009 Default Target
by Max Millennium Chief Observer 09 Jul '24

09 Jul '24

Dear Collaborators, Solar activity was at a moderate-to-low level. The largest event since the last message was an M1.1 flare at 12:34 UT on July 8 produced by the limb target (still unnumbered yet). This limb region also produced a few C-class flares during the period. It is rotating onto the visible solar disk. Another three regions, NOAA 13738 (S08E23, beta-gamma/E-type), 13736 (S18W07, beta/C-type), and 13740 (S17W39, beta/B-type), produced a few C-class flares as well. Further C-class activities are expected with a chance of low M-class flare in the next 24 hours. The approximate position of the target on July 9 at 11:30 UT is: S20E80 (-875", -350") 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 moderate level. The largest event since the last message was an M2.5 flare at 22:03 UT on July 7 produced by a southeast limb region. This limb region also produced three ~M1 and a few ~C5 flares during the period. Today the target will switch to this limb region due to its high flare activity although it is still beyond the east limb mostly. Please note that yesterday's target NOAA 13738 (S09E40) retains a beta-gamma/E-type configuration and produced an M1.0 flare at 23:19 UT on July 7. More C-class activities are expected with a good chance of additional M-class flares from the new target and also NOAA 13738 in the next 24 hours. The approximate position of the target on July 8 at 07:30 UT is: S24E87 (-900", -400") 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 at a low-to-moderate level. Target region NOAA 13729 has now rotated up to the South West limb and although it was classified as an alpha/H-type sunspot group this designation will be hampered by foreshortening effects. This region produced only one flare in the period, a C7.2 on 7-Jul-2024 at 01:56 UT. NOAA 13738 (a beta-gamma/E-type group) has grown in sunspot area and number of spots since the last message to become the most magnetically complex region on the disk. NOAA 13738 has been the most flare-productive region in the period with 6 C-class flares and the only M-class flare - an M1.0 on 6-Jul-2024 at 22:52 UT. NOAA 13738 becomes the new target region. More C-class activity is expected in the next 24 hours, with a good chance for more M-class activity. The position of NOAA 13738 on 7-Jul-2024 at 15:30 UT is: S09E49 , ( -705", -186" ) 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. Target region NOAA 13737 has now rotated up to the South West limb so its magnetic classification is unable to be determined. This region produced 4 C-class flares, including the largest magnitude flare in the period - a C9.4 on 5-Jul-2024 at 18:47 UT. NOAA 13729 (a beta-gamma/E-type sunspot group) is the most magnetically complex region on the disk and increased in flare productivity through the period along with generating the second largest magnitude flare - a C8.6 on 5-Jul-2024 at 20:03 UT. NOAA 13737 will soon rotate out of Earth-view, so NOAA 13729 becomes the new target. Further C-class activity is expected over the following 24-hour period, with a good chance for a low M-class flare. The position of NOAA 13729 on 6-Jul-2024 at 15:30 UT is: S04W61 , ( 824", -93" ) 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 at a low-to-moderate level. Target region NOAA 13730 was the source of the largest magnitude flare in the period - an M1.4 on 4-Jul-2024 at 19:54 UT. After this NOAA 13730 decayed to the point of losing all its spots to become an unnumbered plage region. NOAA 13733 increased quite significantly in sunspot area since the last message, but remained classified as a beta/D-type sunspot group and only produced one C-class flare (a C3.5 on 4-Jul-2024 at 17:59 UT). Newly numbered NOAA 13737 (a beta/D-type spot group) was the most flare-productive region with generating four C-class flares, the largest of which being a C4.1 on 5-Jul-2024 at 15:06 UT. NOAA 13737 becomes the new target for the next 24 hours while it rotates up to the South West limb. Additional C-class flares are expected in the next 24 hours, with a chance for further low M-class activity. The position of NOAA 13737 on 5-Jul-2024 at 15:30 UT is: S14W85 , ( 911", -232" ) 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-to-moderate. Target region NOAA 13730 has decreased slightly in sunspot area and number of spots since the last message, but this is likely partly due to its rotation towards the South West limb. This region has now been reclassified as a beta/B-type sunspot group and produced just one flare, a C4.2 on 4-Jul-2024 at 12:21 UT. The largest magnitude flare in the period, an M1.0 on 4-Jul-2024 at 14:06 UT, came from the plage remnants of the sunspot region previously numbered as NOAA 13723. More C-class activity is expected over the following 24-hour period, with a chance for additional low M-class flares. The position of NOAA 13730 on 4-Jul-2024 at 15:30 UT is: S18W81 , ( 886", -299" ) 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 at a low-to-moderate level. Target region NOAA 13729 has possibly begun its decay with decreasing slightly in sunspot area but increasing number of spots since the last message. NOAA 13729 also gained a delta-spot to become classified as a beta-gamma-delta/E-type sunspot group and again displayed the highest frequency of flaring in the period, producing several C-class flares. The new region near the South East limb has remained flare quiet since the last message, while NOAA 13730 was again the source of the largest magnitude flare in the period, an M1.5 on 3-Jul-2024 at 07:29 UT, so it becomes the target. Additional C-class flares are expected in the next 24 hours, with a chance for another M-class flare. The position of NOAA 13730 on 3-Jul-2024 at 15:30 UT is: S18W67 , ( 827", -310" ) 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. Target region NOAA 13729 has grown slightly in sunspot area and number of spots since the last message, but increased in polarity mixing to become classified as a beta-gamma/F-type sunspot group. NOAA 13729 was again the most flare-productive region with seven C-class flares, the largest being a C2.6 on 2-Jul-2024 at 09:02 UT. The largest magnitude flare in the period was a C3.6 flare on 2-Jul-2024 at 22:27 UT from a new region that is now rotating onto the visible disk over the South East limb. NOAA 13729 remains as the target due to its overall size and complexity, as well as its higher flare rate. More C-class activity is expected over the following 24-hour period, with a chance for a low M-class flare. The position of NOAA 13729 on 2-Jul-2024 at 15:30 UT is: S04W09 , ( 147", -116" ) 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 at a low-to-moderate level. Target region NOAA 13734 has remained stable in terms of sunspot area and number of spots since the last message, and is now classed as a beta/D-type sunspot group. NOAA 13734 was flare-quiet in the period but NOAA 13729 was the most flare productive region with five C-class flares (its largest being a C2.8 on 1-Jul-2024 at 11:32 UT). The largest magnitude flare in the period came as an M2.1 on 1-Jul-2024 at 10:51 UT from NOAA 13730 (an alpha/A-type sunspot group). The target switches to NOAA 13729 due to its overall size and higher flaring rate. Additional C-class activity is expected in the next 24 hours, with a chance for a low M-class flare. The position of NOAA 13729 on 1-Jul-2024 at 19:30 UT is: S04E02 , ( -32", -115" ) 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. Target region NOAA 13723 decayed even further in terms of spot area and number of spots since the last message, and is now classified as a beta/B-type sunspot group. NOAA 12723 was again the source of one C-class flare in the period (a C2.2 on 30-Jun-2024 at 04:07 UT). The new region that produced the largest flare before yesterday's message has now been designated as NOAA 13734 (a beta/C-type sunspot group) and has been the most flare-productive region with three C-class flares, including the largest flare in the period (a C3.8 on 30-Jun-2024 at 05:48 UT). Further C-class flares are expected over the following 24-hour period, with a small chance for an isolated M-class flare. The position of NOAA 13734 on 30-Jun-2024 at 15:30 UT is: N08E61 , ( -818", 108" ) 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.
