MM#009 Default Target
by Max Millennium Chief Observer 10 Feb '24

10 Feb '24

Dear Collaborators, The level of solar activity is moderate. Target region NOAA 13576 grew slightly in terms of sunspot area since the last message while merging some spots. This region continues as a beta-gamma-delta/F-type sunspot group classification. NOAA 13576 again produced several C-class flares in the period, along with an M1.2 flare on 9-Feb-2024 at 17:54 UT and an M1.5 flare on 10-Feb-2024 at 00:42 UT, respectively. A region that is currently beyond the South East limb was the source of the largest magnitude flare in the period, an M3.4 flare on 10-Feb-2024 at 03:04 UT. NOAA 13576 will remain as the default target until more information is available on the new region after it rotates over the South East limb. Further C-class flares are expected in the next 24 hours, with a chance for more M-class flares. The position of NOAA 13576 on 10-Feb-2024 at 20:30 UT is: S16W07 , ( 114", -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 is at a high level. Target region NOAA 13576 was stable in terms of sunspot area since the last message, and remains classified as a beta-gamma-delta/F-type sunspot group. This region produced several C-class flares in the period, along with an M3.2 flare on 9-Feb-2024 at 00:36 UT. NOAA 13575 produced an M3.9 flare on 8-Feb-2024 at 23:16 UT while at the South West limb, followed by an X3.4 flare on 9-Feb-2024 at 12:53 UT after having rotated over the limb. At this point we are not initiating a Major Flare Watch because NOAA 13575 is currently rotating out of Earth-view. NOAA 13576 will remain the default target. Additional C-class activity is expected over the following 24-hour period, with a good chance for further M-class flares. The position of NOAA 13576 on 9-Feb-2024 at 15:00 UT is: S16E09 , ( -143", -162" ) 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 13576 has grown marginally in terms of sunspot area since the last message by consolidating some spots, and it remains classified as a beta-gamma-delta/F-type sunspot group. NOAA 13576 was the most flare-productive region in the period, with multiple C-class and two M-class flares (an M3.5 and M1.8 on 8-Feb-2024 at 12:41 UT and 15:17 UT, respectively), which includes the largest magnitude flare. Further C-class flaring is expected in the next 24 hours, with good chances for additional M-class flares. The position of NOAA 13576 on 8-Feb-2024 at 16:30 UT is: S15E51 , ( -732", -185" ) 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-to-high level. Target region NOAA 13576 has displayed polarity mixing and separation of its main spots since the last message, so was re-classified as a beta-gamma-delta/F-type sunspot group. This region produced several C-class flares and an M1.4 flare on 7-Feb-2024 at 17:41 UT. NOAA 13575 showed signs of decay and produced an M5.2 flare on 7-Feb-2024 at 03:04 UT as it rotated up to the South West limb. Despite NOAA 13575 producing a >M5 flare, at this stage the target region will remain as NOAA 13576 due to its delta spot involving a long narrow excursion into the main leading spot. Additional C-class activity is expected over the following 24-hour period, with a good chance for more M-class activity. The position of NOAA 13576 on 7-Feb-2024 at 22:00 UT is: S16E34 , ( -524", -180" ) 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 13576 has been stable in terms of sunspot area and number of spots since the last message and remains classified as a beta-delta/E-type sunspot group, but may also have a gamma classification move visible as this rotates further on disk. This region produced only C-class flares in the period, while NOAA 13575 produced an M4.3 flare on 6-Feb-2024 at 02:37 UT - the largest magnitude flare. NOAA 13575 has undergone some consolidation of spots over the past 2 days and is classified as a beta-gamma-delta/D-type sunspot group. The default target region will remain with NOAA 13576 due to its overall size and prior flaring history. Further C-class flaring is expected in the next 24 hours, with a chance for more M-class flares. The position of NOAA 13576 on 6-Feb-2024 at 11:00 UT is: S15E51 , ( -732", -185" ) 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 a moderate level in the last 24 hours. The largest event since the last message was an M1.4 flare at 11:40 UT today from the target region, which was now numbered as NOAA 13576. This region was classified as a beta/D-type configuration. It was still the most productive and became more active, with a high and increasing current helicity. Today the target shall remain with NOAA 13576. Further C-class activities are expected, with a good chance of another low-M flare in the following 24 hours. The position of NOAA 13576 on 4-Feb-2024 at 12:30 UT is: S17E75 (-899", -257") 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 decreased slightly since the last message. An unnumbered region near the South East limb produced the largest flare that was a C7.7 flare at 05:31 UT today. This region also produced a C5.8 flare and 4 low-C flares, where EUV images show dynamic activities. Today the target shall switch to this limb region. Yesterday’s target region NOAA 13571 was only a source of 3 low-level flares, with signs of decay. Further C-class activities are expected, with a low-M flare likely in the coming 24-48 hours. The approximate position of the target on 3-Feb-2024 at 11:30 UT is: S16E88 (-950", -300") 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 a moderate level. The largest event since the last message was an M1.2 flare at 02:52 UT today from NOAA 13571. This region was also the source of a C5.7 flare plus several low-C flares. It has been classified as an alpha/H-type sunspot group, with the emergence of new magnetic fluxes. 13571 should become the new target due to its recent high frequency of flaring activity. Yesterday’s target NOAA 13567 only produced a C1 flare. Further C-class activities are expected, with a chance of another low-M flare in the following 24 hours. The position of NOAA 13571 on 2-Feb-2024 at 12:30 UT is: S16E54 (-758", -209") 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 to a low level in the past 24 hours. Target region NOAA 13567 was a source of 6 C1 flares. It continued to be classified as a beta/D-type configuration and to increase in sunspot area and counts. Today the target shall remain with NOAA 13567. Please also note that a newly emerged region (N25E02) that was unnumbered yet produced the largest event, a C3.1 flare at 07:22 UT today. Additional C-class activities are expected in the next 24-hour period. The position of NOAA 13567 on 1-Feb-2024 at 12:30 UT is: N19E47 (-674", 381") 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 still at an intermediate level since the last message. Yesterday’s target region NOAA 13559 produced 6 C-class flares, including the largest magnitude flare (a C5.7 flare at 17:34 UT on 30-Jan-2024), but it has almost rotated beyond the west limb. A newly numbered region NOAA 13567 has been classified as a beta/D-type configuration. It was a source of several low-C flares and has shown signs of additional flux emergence in the period. Today we shall end the Major Flare Watch campaign, and the default target shall switch to NOAA 13567. Further C-class activities are expected in the following 24 hours. The position of NOAA 13567 on 31-Jan-2024 at 08:30 UT is: N20E65 (-830", 371") 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.
