MM#009 Default Target
by Max Millennium Chief Observer 15 Sep '23

15 Sep '23

Dear Collaborators, The level of solar activity is at a moderate level. Target region NOAA 13429 has evolved slightly since the last message, reported as having decreased in magnetic classification to be a beta/E-type sunspot group at the start of the UT day. However, 13429 appears to now have a small delta configuration in its intermediate spots. NOAA 13429 produced the vast majority of flare activity in the period with being the source of many C-class flares and the only M-class flares - an M1.9 and an M2.5 on 14-Sep-2023 at 19:23 UT and 21:17 UT, respectively. Further C-class flares are expected over the next 24 hours, with a good chance for more low M-class activity. The position of NOAA 13429 on 15-Sep-2023 at 18:00 UT is: N10W05 , ( 82", 47" ) 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 13423 has decayed further since the last message, now classified as a beta/E-type sunspot group. This region produced one C-class flare in the period, while NOAA 13429 (a beta-gamma/E-type group) was the source of multiple C-class flares and the largest flare in the period (an M1.4 on 14-Sep-2023 at 06:40 UT). The increased activity in NOAA 13429 is related to a period of significant flux emergence since the last message. Additional C-class activity is expected in the following 24-hour period, with a good chance for another low M-class flare. The position of NOAA 13429 on 14-Sep-2023 at 18:00 UT is: N10E08 , ( -132", 48" ) 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 13423 has undergone slight decay since the last message, but has remained a beta-gamma/E-type sunspot group classification. NOAA 13423 produced the two largest flares in the period - a C5.6 on 12-Sep-2023 at 21:50 UT and a C5.5 on 13-Sep-2023 at 08:04 UT. C-class activity is expected over the next 24 hours, with a chance for another low M-class flare. The position of NOAA 13423 on 13-Sep-2023 at 18:00 UT is: N16W54 , ( 742", 193" ) 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 moderate level. Target region NOAA 13431 has remained stable since the last message, but developed a weak delta to be classified as a beta-delta/D-type sunspot group. This region only produced one C-class flare in the period, while NOAA region 13425 (a beta/E-type) was the source of an M1.9 flare on 12-Sep-2023 at 04:18 UT and 13423 (a beta-gamma/E-type) produced the largest magnitude flare - an M2.6 on 12-Sep-2023 at 06:47 UT. The target switches back to NOAA 13423 because of its return to M-class flaring. Additional C-class flares are expected over the following 24-hour period, with a good chance for further M-class flares. The position of NOAA 13423 on 12-Sep-2023 at 18:00 UT is: N16W40 , ( 589", 173" ) 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 moderate. Target region NOAA 13423 has been stable in sunspot area and number of spots since the last message, but was confirmed as a beta-gamma/E-type sunspot group at the start of the UT day. This region has only produced one C-class flare in the period, while NOAA regions 13429 (a beta/C-type) was the source of an M1.4 flare on 11-Sep-2023 at 01:08 UT and 13431 (a beta/D-type) produced two M1.1 flares on 11-Sep-2023 at 03:58 UT and 14:38 UT. The target switches to NOAA 13431 which appears to have a more mixed polarity configuration. C-class activity is expected in the next 24 hours, with a good chance for additional low-to-mid M-class flares. The position of NOAA 13431 on 11-Sep-2023 at 22:00 UT is: S08E48 , ( -701", -212" ) 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 13425 has decayed slightly in sunspot area and number of spots since the last message and was confirmed as a beta/D-type sunspot group. This region has produced two low C-class events in the period, while NOAA 13423 (beta/E-type sunspot group) increased in its frequency of flaring and produced the largest magnitude event in the period (a C8.3 flare on 10-Sep-2023 at 01:41 UT). The target switches to NOAA 13423 due to its higher flaring rate. C-class activity is expected over the following 24-hour period. The position of NOAA 13423 on 10-Sep-2023 at 18:00 UT is: N12W13 , ( 209", 82" ) 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 13425 was classified as a beta-gamma/D-type sunspot group at the start of the UT day, but appears to only display a beta configuration at the current time. NOAA 13425 has been flare-quiet since the last message while NOAA 13421 (a beta/E-type group) produced C-class activity as it rotates towards the North East limb, including the largest magnitude event in the period (a C8.5 on 9-Sep-2023 at 01:15 UT). The target will remain on NOAA 13425 because 13421 has decayed significantly at this point. More C-class flares are expected in the next 24 hours. The position of NOAA 13425 on 9-Sep-2023 at 17:00 UT is: N23E34 , ( -489", 278" ) 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 13421 has continued to fragment since the last message but this has resulted in increasing its complexity to a beta-gamma/E-type classification. NOAA 13421 has only produced one C-class flare, while NOAA 13425 (a beta/D-type group) was the source of several C-class flares and the largest magnitude event in the period (an M2.1 flare on 7-Sep-2023 at 18:58 UT). Further C-class activity is expected over the following 24-hour period, with a chance for another low M-class flare. The position of NOAA 13425 on 8-Sep-2023 at 17:00 UT is: N23E47 , ( -641", 294" ) 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 13421 has shown signs of decay since the last message, its leading polarity spots fragmenting somewhat. Despite this, 13241 has remained as a beta/D-type sunspot group classification. This region has continued to produce C-class activity, including the largest magnitude event in the period - a C3.5 flare on 6-Sep-2023 at 20:43 UT. More C-class flares are expected in the next 24 hours, with a small chance for an isolated low M-class flare. The position of NOAA 13421 on 7-Sep-2023 at 18:00 UT is: N14W36 , ( 544", 135" ) 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 13421 has grown slightly in spot area since yesterday's last message, remaining classified as a beta/D-type sunspot group. NOAA 13421 continues to be the most flare-productive region, generating multiple C-class flares and two M-class flares that were the largest magnitude events in the period (an M1.2 and an M1.0 on 5-Sep-2023 at 19:33 UT and 23:21 UT, respectively). Additional C-class flares are expected over the following 24-hour period, with a good chance for further low M-class activity. The position of NOAA 13421 on 6-Sep-2023 at 18:00 UT is: N14W24 , ( 376", 122" ) 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.
