MM#009 Default Target
by Max Millennium Chief Observer 30 Apr '24

30 Apr '24

Dear Collaborators, Solar activity remains at a low level. A number of flares were produced in the last 24 hours, the largest being an M1.6 from NOAA 13654 at 00:46 UT today. NOAA 13654 remains classified as a beta-gamma-delta type region with an increased area of 480 μh. NOAA 13654 will continue as the target region as it approaches the southwest limb, further C-class activity is expected with a slight chance for additional M-class activity. The position of NOAA 13654 on 30-Apr-2024 at 11:30 UT is: S07W57, (794",-78") 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 continued at a low-to-moderate level since the last message. Several flares were produced in the last 24 hours, the largest being an M3.7 from NOAA 13654 at 00:54 UT today. NOAA 13654 has developed into a beta-gamma-delta type region with an area of 310 μh. This region also shows some signs of emerging flux and dynamic sunspot behaviour. NOAA 13654 will continue as the target region, with a chance for additional isolated M-class activity in the next 24 hours. The position of NOAA 13654 on 29-Apr-2024 at 11:30 UT is: S07W43, (646",-64") 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 13654 grew in sunspot area but maintained its number of spots to continuing to be classified as a beta-gamma/E-type sunspot group. NOAA 13654 appears to show signs of developing a magnetic delta configuration in its intermediate spots. This region has produced many C-class flares and the only M-class flare in the period - an M3.0 on 27-Apr-2024 at 21:29 UT. Additional C-class flares are expected over the following 24-hour period, with a good chance for another low M-class flare. The position of NOAA 13654 on 28-Apr-2024 at 19:30 UT is: S08W35 , ( 542", -73" ) 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 13638 has now rotated completely out of view beyond the South West limb. The most flare-productive region since the last message was NOAA 13654, which has maintained sunspot area and number of spots to continue being classified as a beta-gamma/E-type sunspot group. NOAA 13654 was the source of several C-class and the only M-class flare in the period (an M2.1 on 27-Apr-2024 at 12:23 UT). Further C-class activity is expected in the next 24 hours, with a chance for a low M-class flare. The position of NOAA 13654 on 27-Apr-2024 at 19:30 UT is: S08W20 , ( 324", -63" ) 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 13645 has now rotated over the South West limb. The most flare-productive region in the period was NOAA 13638 that has now rotated up to the South West limb (where it was classified as a beta/C-type sunspot group the previous day). NOAA 13638 was the source of several C-class flares and an M1.3 flare on 25-Apr-2024 at 17:03 UT (the largest magnitude event). The default target switches to the limb-exiting location of NOAA 13638 because the coronal loop structure will remain visible for most of the next 24 hours. C-class activity is expected over the following 24-hour period, with a chance for a low M-class flare. The approximate position of this region on 26-Apr-2024 at 14:00 UT is: S17W90 , ( 911", -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, The level of solar activity is moderate. Target region NOAA 13645 remained stable in sunspot area and number of spots since the last message, continuing in classification as a beta-gamma/D-type spot group. This region was one of three to produce low M-class flares in the period (an M1.0 on 25-Apr-2024 at 01:40 UT) with the other NOAA regions being 13647 (a beta/D-type spot group, with an M1.1 on 24-Apr-2024 at 22:27 UT) and 13638 (a beta/C-type spot group, with an M2.0 on 24-Apr-2024 at 22:54 UT and M1.0 on 25-Apr-2024 at 13:11 UT). The default target will remain as NOAA 13645, but their close proximity to each other and strong foreshortening effects with being near the South West limb may allow observers to include NOAA 13645 and one or both of these other two regions within their field-of-view. More low M-class activity is probable in the next 24 hours, with a chance for a >M5 flare. The position of NOAA 13645 on 25-Apr-2024 at 16:00 UT is: S08W80 , ( 930", -119" ) 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 13654 grew in sunspot area and number of spots since the last message, adding penumbrae to its trailing polarity to be classified as a beta/D-type sunspot group. This region did not produce any more significant flares in the period. In contrast, some low M-class flares were produced by both NOAA 13638 (a beta/B-type sunspot group, with an M1.8 on 24-Apr-2024 at 02:30 UT) and NOAA 13645 (a beta-gamma/D-type sunspot group, with an M1.7 and an M1.4 on 24-Apr-2024 at 00:13 UT and 12:07 UT, respectively). The default target switches back to NOAA 13645 as it rotates up to the South West limb. Additional low M-class flares are probable over the following 24-hour period, with a chance for a >M5 flare. The position of NOAA 13645 on 24-Apr-2024 at 20:00 UT is: S08W75 , ( 913", -112" ) 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 13645 maintained spot area and number of spots since the last message, remaining classified as a beta-gamma/D-type sunspot group. This region was the source of several high C-class flares and an M2.9 flare on 23-Apr-2024 at 17:33 UT. The largest magnitude flare in the period was an M3.6 on 23-Apr-2024 at 03:06 UT that came from NOAA 13654 (a beta/C-type group), the same region that produced an M3.0 on 23-Apr-2024 at 08:07 UT. The default target switches to NOAA 13654 because this region seems to be emerging new flux. More low-to-mid M-class flares are likely in the next 24 hours, with a chance for a >M5 flare. The position of NOAA 13654 on 23-Apr-2024 at 19:30 UT is: S09E33 , ( -514", -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, Solar activity is at a moderate level. Target region NOAA 13645 has emerged some magnetic flux since the last message, increasing in sunspot area and number of spots. As a result, this region changed in classification to be a beta-gamma/D-type group. NOAA 13645 was the source of two M-class flares in the period (an M1.0 and an M1.6 on 22-Apr-2024 at 07:59 UT and 13:13 UT, respectively), while the largest magnitude flare was an M3.4 on 21-Apr-2024 at 21:44 UT from NOAA 13638 (beta/C-type group located close to NOAA regions 13645 and 13647). The default target continues as NOAA 13645 for the next 24 hours due to being larger with more complex sunspot structure. However, all regions in this Southern-hemisphere complex are being monitored for their evolution and a possible upgrading to a MM#003 Major Flare Watch. Further low M-class activity is probable over the following 24-hour period, with a chance for a >M5 flare. The position of NOAA 13645 on 22-Apr-2024 at 16:00 UT is: S09W43 , ( 643", -89" ) 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 13647 has again remained stable in terms of spot area and number of spots since the last message, but has not produced any significant flares. The majority of flares were produced by NOAA regions 13638 (a beta/C-type sunspot group) and NOAA 13645 (a beta/D-type sunspot group) - NOAA 13638 generated three C-class flares and an M2.2 (on 21-Apr-2024 at 15:07 UT), while NOAA 13645 generated five C-class flares and an M1.0 (on 21-Apr-2024 at 12:39 UT). At this point the MM#003 Major Flare Watch terminates. The default target switches to NOAA 13645 because of its more central location in the cluster of active regions in the Southern hemisphere. More C-class activity is expected in the next 24 hours, with a chance for low M-class flares. The position of NOAA 13645 on 21-Apr-2024 at 15:30 UT is: S09W27 , ( 429", -75" ) 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.
