MM#009 Default Target

03 Nov '23

Dear Collaborators, Solar activity has reached moderate levels. The target region (unnumbered yet) has produced 4 flares including an M1.0 at 19:08 UT on 2-Nov-2023, with a high and increasing current helicity. Today the target shall remain with this limb region due to its recent high flaring productivity. Besides, NOAA 13474 (S18W47, beta-gamma/D-type) produced the largest event which was an M1.7 flare at 12:18 UT on 2-Nov-2023. A spotless region (N31W26) produced a C3.2 flare at 04:40 UT today, accompanied by a large filament eruption. Further C-class flares are expected with additional moderate-level activity possible from various regions in the next 24-hour period. The approximate position of the target on 3-Nov-2023 at 08:30 UT is: S11E86 (-900", -190") 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 decreased since the last message. Yesterday’s target NOAA 13477 (S15E61, alpha/H-type) did not produce any flare in the period. An unnumbered region near the South East limb was the most productive and was the source of 6 C-class flares including the largest one that was a C6.5 flare at 06:12 UT today. The target shall switch to this limb region. Please note that NOAA 13472 (N20W44, beta/B-type) and NOAA 13474 (S18W34, beta-gamma/D-type) also produced several low-C flares. Further C-class flares are expected with a low-M flare possible in the following 24 hours. The approximate position of the target on 2-Nov-2023 at 11:30 UT is: S08E89 (-940", -160") 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 reached moderate levels due to 2 M1 flares (an M1.4 at 11:37 UT and an M1.2 at 06:07 UT today) from NOAA 13477. This newly numbered region was very active and also produced 7 C-class flares. It was classified as an alpha/H-type sunspot group. Today the target shall switch to NOAA 13477 because of its high flaring productivity. Yesterday’s target NOAA 13474 (S18W22, beta-gamma/D-type) only produced a C5.0 and a C3.7 flare. Further C-class flares are expected with a good chance of another low-M flare in the next 24 hours. The position of NOAA 13477 on 1-Nov-2023 at 12:30 UT is: S12E73 (-904", -221") 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 an intermediate level. Target region NOAA 13474 is still experiencing the emergence of new magnetic fluxes and retains a beta-gamma/D-type sunspot group, with the largest spot area on the disk. This region continued being the source of low-C flares since the last message, but the largest event in the period was a C5.7 flare at 00:10 UT today from NOAA 13473 (N16E13, beta-gamma/D-type) composed of small pores. The target shall continue as NOAA 13474 due to its higher spot maturity and past flaring history. Further C-class flares are expected in the following 24-hour period. The position of NOAA 13474 on 31-Oct-2023 at 12:30 UT is: S18W09 (144", -370") 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 an intermediate level. The target region NOAA 13474 produced 4 C-class and 1 B-class flares, including the largest magnitude event in the period - a C7.9 at 13:00 UT on 29-Oct-2023. 13474 retains active and has been classified as a beta-gamma/D-type sunspot group, with a higher complexity of configuration and an apparent increase of sunspot size plus counts. Today the target shall remain with NOAA 13474. Further C-class flares are expected with a low-M flare possible in the next 24-48 hours. The position of NOAA 13474 on 30-Oct-2023 at 08:30 UT is: S17E07 (-113", -356") 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 has increased in the past 24 hours. The largest event since the last message was a C6.6 flare at 11:30 UT today from NOAA 13474. 13474 was also the source of 4 low-C plus 2 B-class flares and became the most productive. It was classified as a beta/B-type sunspot group, with the emergence of new sunspots and new magnetic fluxes. Yesterday’s target NOAA 13473 did not produce any flares in the period, so the target region shall switch to NOAA 13474. Please note that NOAA 13471 (S23W64, beta /B-type) also produced a C1 flare. Further C-class flares are expected with a chance of a low-M flare in the following 24 hours. The position of NOAA 13474 on 29-Oct-2023 at 12:30 UT is: S17E18 (-286", -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.

Dear Collaborators, Solar activity has returned to low levels. The largest event since the last message was a C1.7 flare at 06:09 UT today produced by the target region NOAA 13473. This region also produced 2 C1.2 and 1 B-class flares. It retains a beta/B-type magnetic configuration and has increased in spot counts. The target region shall remain with NOAA 13473, due to its past flaring history as well as a high and increasing current helicity. Besides, NOAA 13471 (S23W53, beta-gamma/C-type) and NOAA 13472 (N19E22, beta/C-type) were also sources of several C1 and B-class flares. Further C-class flares are expected in the following 24-hour period. The position of NOAA 13473 on 28-Oct-2023 at 11:30 UT is: N16E50 (-712", 216") 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 reached an intermediate due to an M1.4 at 22:47 UT on 26-Oct-2023 from an unnumbered region near North East limb (N18E80). This region was close to the recently numbered target region NOAA 13473. 13473 was now classified as a beta/B-type sunspot group and the source of 3 low-C flares. Today the target region shall still be 13473, but if possible, please include the unnumbered region (N18E80) in your field of view. Additionally, NOAA 13471 (S23W37, beta/D-type) and its nearby spotless region also produced 3 low-C flares. Further C-class flares are expected with a chance of another M-class flare in the next 24 hours. The position of NOAA 13473 on 27-Oct-2023 at 07:30 UT is: N13E58 (-799", 174") 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 low levels since the last message. The target region (still unnumbered) has produced 3 C1 and 3 B-class flares. It should continue as the target region due to its high flaring productivity and increasing current helicity. Additionally, some plage regions (S15E81, N31W21, N17E43) and NOAA 13471 (S23W27, beta/C-type) also produced some low-C and B-class flares. More C-class flares are expected in the following 24-hour period. The approximate position of the target on 26-Oct-2023 at 11:30 UT is: N09E77 (-890", 150") 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.
