MM#009 Default Target
by Max Millennium Chief Observer 25 Oct '23

25 Oct '23

Dear Collaborators, Solar activity has increased slightly due to multiple low-C flares from several regions. The most productive region over the North East limb (unnumbered yet) was the source of 6 low-C and 7 high-B flares, including the largest one that was a C2.6 at 00:38 today. The target shall switch to this limb region due to its current level of flaring, but if possible, please also include a spotless region (N16E59) in your field of view, which produced the largest event being a C4.2 flare at 23:49 on 24-Oct-2023. Yesterday’s target NOAA 13468 was flare-quiet. Besides, another unnumbered region (S13E88) and NOAA 13469 also produced a few low-C flares. Further C-class activities are likely from various regions with a slight chance of a low M-class flare in the next 24-hour period. The approximate position of the target on 25-Oct-2023 at 11:30 UT is: N14E88 (-900", 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.

Dear Collaborators, Solar activity is still at a low level. The largest event since the last message was a C2.3 flare at 19:47 UT on 23-Oct-2023 produced by the close pair of the target region NOAA 13468 and a plage region (S14W25). 13468 (alpha/H-type) was stable in its magnetic complexity and shall still be the target. Interested observers should also try to include the plage region (S14W25) in their field-of-view if possible. C-class activity is possible in the following 24 hours. The position of NOAA 13468 on 24-Oct-2023 at 07:30 UT is: S09W29 (463", -225") 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, Solar activity continues at low levels. Yesterday’s target (NOAA 13467) did not produce any flares in the period, while NOAA 13468 produced a single flare that was the largest magnitude (a C1.5 flare at 06:58 UT today). This region retains its alpha/H-type magnetic configuration, so it becomes the new target. B-class activities are expected with low C-class flares probable in the next 24 hours. The position of NOAA 13468 on 23-Oct-2023 at 07:30 UT is: S09W14 (231", -235") 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 very low. Target region NOAA 13469 remained stable since the last message, continuing to be classed as a beta/D-type group. The plage region that was previously NOAA 13467 has regained this numbering after forming new spots. 13467 (an alpha/A-type group) becomes the new target. C-class activity is possible in the next 24 hours. The position of NOAA 13467 on 22-Oct-2023 at 20:00 UT is: N14W37 , ( 565", 164" ) 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 very low level. The target region at the North West limb has rotated beyond Earth view. The plage region that used to be NOAA 13467 produced the largest flare since the last message, a C2.8 on 21-Oct-2023 at 00:00 UT. Newly numbered NOAA 13469 (a beta/D-type group) was the only spotted region showing any flux emergence, and this becomes the new target. C-class activity is probable over the following 24-hour period. The position of NOAA 13469 on 21-Oct-2023 at 18:30 UT is: N27W47 , ( 628", 382" ) 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 very low. The target region at the North West limb has continued to be the source of all C-class activity since the last message (five flares in total, including the largest magnitude in the period as a C2.3 flare on 20-Oct-2023 at 04:20 UT. This location remains as the target for the following 24 hours. Additional low C-class flares are expected in the next 24 hours. The approximate position of this region on 20-Oct-2023 at 20:00 UT is: N25W90 , ( 873", 405" ) 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 very low level. The target region at the North West limb has continued to be the source of C-class activity in the form of three flares that included the largest flare in the period - a C2.7 on 19-Oct-2023 at 13:52 UT. This limb location remains as the target for the next 24-hour period because the three spotted regions on disk have all shown signs of decay and were unremarkable in terms of flaring. More low C-class flares are probable over the following 24-hour period. The approximate position of this region on 19-Oct-2023 at 18:00 UT is: N23W90 , ( 886", 374" ) 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 very low. Target region NOAA 13463 has decayed losing its spots, and remained flare quiet since the last message. The largest flare in the period came from the North West limb - a C1.6 on 18-Oct-2023 at 01:31 UT. This limb location becomes the target for the following 24-hour period because the 3 spotted regions on disk have been stable in terms of magnetic flux and unremarkable in terms of flaring. C-class activity is probable in the next 24 hours. The approximate position of this region on 18-Oct-2023 at 18:00 UT is: N27W90 , ( 858", 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, Solar activity is at a low level. The target region near the North East limb has rotated on disk but was flare quiet since the last message. It remained unnumbered at the start of the UT day, but appears to have a small sunspot in its leading polarity flux and an overall beta magnetic configuration. NOAA 13463 (an alpha/A-type sunspot group) was the most flare-productive region in the period with two C-class flares including the largest magnitude flare - a C2.2 on 17-Oct-2023 at 04:27 UT. NOAA 13463 becomes the target. C-class flares are probable in the following 24-hour period. The position of NOAA 13463 on 17-Oct-2023 at 18:00 UT is: S17W40 , ( 592", -351" ) 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 13464 remained stable since the last message, continuing to be classified as a beta/ C-type sunspot group. NOAA 13464 produced one C-class flare in the period, while a new region that is currently rotating into view over the North East limb produced the largest magnitude flare - a C9.9 on 16-Oct-2023 at 15:59 UT. This new limb region becomes the new target. Further C-class activity is expected over the next 24 hours, with a small chance for a low M-class flare. The approximate position of this region on 16-Oct-2023 at 18:00 UT is: N24E87 , ( -878", 385" ) 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.
