MM#009 Default Target
by Max Millennium Chief Observer 05 Oct '23

05 Oct '23

Dear Collaborators, Solar activity is at a low level. Target region NOAA 13450 has continued to decay since the last message, decreasing slightly in spot area and magnetic classification to be designated as a beta/E-type group. This region produced just one C-class flare in the period, while most of the remaining flares came from the close pair of NOAA regions 13451 (a beta/D-type group with five C-class flares) and 13452 (a beta/E-type group, with one C-class flare). The target switches to 13451 which is the smaller spot group, but produced the largest magnitude flare (a C3.8 flare on 5-Oct-2023 at 06:51 UT). Interested observers should try to include 13452 in their field-of-view as well if possible. More C-class flares are expected in the following 24-hour period. The position of NOAA 13451 on 5-Oct-2023 at 18:00 UT is: N12W02 , ( 32", 92" ) 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 13450 has decayed since the last message, decreasing in both spot area and number of spots while remaining classified as a beta-gamma/E-type group. This region has continued to produce C-class activity, but at a lower rate than the previous day. Additional C-class flares are expected over the next 24 hours. The position of NOAA 13450 on 4-Oct-2023 at 20:00 UT is: S19W21 , ( 325", -408" ) 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. Target region NOAA 13451 has decayed further since the last message, decreasing in spot area and magnetic complexity to a beta/D-type group classification. NOAA 13451 has been flare-quiet in the period, while NOAA 13450 (a beta-gamma/E-type group) has produced the most flares - 9 C-class flares, including the largest flare that was a C3.6 on 3-Oct-2023 at 16:56 UT. The target switches to NOAA 13450 due to its higher complexity and current level of flaring. Further C-class activity is expected in the following 24-hour period. The position of NOAA 13450 on 3-Oct-2023 at 20:00 UT is: S18W07 , ( 111", -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, The level of solar activity is low-to-moderate. Target region NOAA 13451 has decayed slightly since the last message, but remained as a beta-delta/D-type group classification at the start of the UT day (although it may have now lost its delta configuration). NOAA 13451 has produced two C-class flares in the period, while an unnumbered small spot region in the North East quadrant was the source of the largest flare - an M1.9 on 2-Oct-2023 at 12:35 UT. The target will remain with NOAA 13451 due to its past flaring history and proximity to NOAA 13452. Additional C-class activity is expected over the next 24 hours. The position of NOAA 13451 on 2-Oct-2023 at 20:00 UT is: N16E37 , ( -557", 178" ) 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 level since the last message. The largest event in the period was an M2.5 flare at 01:10 UT today produced by the target region that has been numbered as NOAA 13451 (N14E56). 13451 is now classified as a beta-delta/D-type sunspot region and produced another M1.2 plus eleven C-class flares in the period. Today the target shall still be this region. Additionally, NOAA 13445 (S14W83, alpha/H-type) also produced two C9 and one C4 flares during its approach to the South West limb. More C-class flares are expected in the following 24-hour period, with a good chance for further low M-class flares. The position of NOAA 13451 on 1-Oct-2023 at 07:30 UT is: N14E56 (-772" , 169") 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-intermediate level. Yesterday's target NOAA 13450 (S19E39) only produced a C1.9 flare in the period, although it was classified as a beta-gamma/E-type sunspot region. A newly emerged region (unnumbered yet) near the North East limb was the most flare-productive region with being the source of ten C-class flares, including two ~C7 flares that erupted at 09/29/18:11 UT and 09/30/03:57 UT respectively. This region continues to undergo flux emergence and shall be the new target. Besides, NOAA 13445 (S14W69, beta/C-type) also produced four C-class flares, including the largest magnitude flare in the period - a C8.0 at 09/30/05:56 UT, but showing signs of decay. Further C-class flares are expected over the next 24-hour period, with a slight chance of low M-class activities. The approximate position of the target on 30-Aug-2023 at 11:00 UT is: N11E68 (-760", 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.

Dear Collaborators, Solar activity is at a low level. The largest event since the last message was a C3.1 flare at 13:56 UT yesterday from the target region NOAA 13450 (S19E54, beta/D-type), which has increased in terms of spot area and number of spots and produced another two ~C2 flares in the period. Today the target shall still be this region. Please note that NOAA 13445 (S14W53, beta/D-type) produced five low-C flares in the period, but decreased significantly in number of spots. Additional low C-class flares are expected in the following 24-hour period. The position of NOAA 13450 on 29-Sep-2023 at 07:30 UT is: S19E54 (-733" , -373") 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 intermediate levels since the last message. The largest event in the period was an M1.3 flare at 08:58 UT today from a newly numbered region NOAA 13450 (S18E59, beta/C-type) that recently rotated on disk over the South East limb. 13450 was the most flare-productive region, which also produced six C-class flares in the period. Yesterday's target region NOAA 13445 (S13W44, beta/D-type) was quiescent in the past 24 hours. Today the target region shall switch from NOAA 13445 to NOAA 13450. Additional C-class flares are expected over the next 24 hours, with a chance for low M-class flares. The position of NOAA 13450 on 28-Sep-2023 at 11:30 UT is: S18E59 (-781" , -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 is at a low level. The largest event was a C4.7 flare at 05:35 UT today produced by a South East limb region (unnumbered yet, S21E86). Target region NOAA 13445 produced two low-to-mid flares (C4.3 and C3.2) in the period. This region has increased slightly in number of spots since the last message, but has decreased in magnetic classification to be a beta-gamma/D-type sunspot group. NOAA 13445 will remain the target region for a further 24 hours. Please note that a newly-numbered NOAA region 13449 (N15E40, beta-gamma/C-type) also produced four low C-class flares in the period. Additional C-class flares are expected over the following 24-hour period, with a slight chance of low M-class activities. The position of NOAA 13445 on 27-Sep-2023 at 11:30 UT is: S13W30 (467" , -311") 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 13445 has become more fragmented since the last message and retained its beta-delta/D-type magnetic configuration. 13445 continued to be the most flare-productive region with being the source of eleven C-class flares, including the largest magnitude event in the period (a C5.7 on 26-Sep-2023 at 04:22 UT). NOAA 13445 shall continue as the target region. Additional C-class flares are expected over the following 24-hour period, with a slight chance of low M-class activities. The position of NOAA 13445 on 26-Sep-2023 at 07:30 UT is: S14W13 (209" , -340") 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.
