MM#009 Default Target
by Max Millennium Chief Observer 31 Aug '24

31 Aug '24

Dear Collaborators, The level of solar activity is moderate. Target region NOAA 13806 has emerged new magnetic flux since the last message, growing in sunspot area and number of spots with a corresponding increase in complexity to be classed as a beta-gamma-delta/F-type sunspot group. NOAA 13807 (a beta-gamma/D-type sunspot group) produced four C-class flares in the period. A region currently located beyond the South East limb also produced C-class flares and an M1.2 on 31-Aug-2024 at 08:52 UT, while target NOAA 13806 produced three M-class flares - an M1.1, M1.2, and M1.8 on 31-Aug-2024 at 00:38 UT, 02:26 UT, and 12:50 UT, respectively. Additional C-class activity is expected over the next 24-hour period, with a strong chance of a mid-M-class flare. The position of NOAA 13806 on 31-Aug-2024 at 15:30 UT is: S11E31 , ( -482" , -280" ) 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 13806 has grown in terms of spot area and number of spots since the last message, although this is likely related to it rotating onto the visible disk and being affected by foreshortening to a lesser degree rather than undergoing significant magnetic flux emergence. However, NOAA 13806 has remained classified as a beta/D-type sunspot group. This region produced C-class activity in the period along with the only two M-class flares - an M1.2 and M3.8 on 30-Aug-2024 at 02:00 UT and 12:13 UT, respectively. This region will be monitored closely for a potential Major Flare Watch if activity increases or a delta-spot configuration develops. C-class flares are expected in the following 24 hours, with a strong chance for more M-class flares. The position of NOAA 13806 on 30-Aug-2024 at 15:30 UT is: S10E47 , ( -686" , -244" ) 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 13796 has continued to decay in the past 24 hours, decreasing in spot area and number of spots. NOAA 13796 again remained classified as a beta-gamma/D-type sunspot group, and produced one C-class flare in the period - a C5.6 on 29-Aug-2024 at 05:26 UT. The South East limb region mentioned in yesterday's message has now been designated as NOAA 13806 (a beta/D-type sunspot group) and once again was the source of the largest magnitude flare in the period - a C7.0 on 29-Aug-2024 at 04:07 UT. Note that the Mt Wilson magnetic and McIntosh white-light structural classifications for NOAA 13806 are still affected by its proximity to the limb at the start of the UT day. This region seems to be reasonably mature with its main leading and trailing polarity spots being quite close together, so NOAA 13806 becomes the new target. Further C-class activity is expected over the following 24-hour period, with a chance for a low M-class flare. The position of NOAA 13806 on 29-Aug-2024 at 15:30 UT is: S10E59 , ( -803" , -224" ) 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 13796 was decayed since the last message, decreasing in spot area and number of spots as it rotates towards the South West limb but remaining classified as a beta-gamma/D-type sunspot group. NOAA 13796 produced one C-class flare in the period (a C3.8 on 28-Aug-2024 at 01:24 UT), while the largest magnitude flare was a C5.0 on 28-Aug-2024 at 14:50 UT that appears to have originated from a new region beyond the South East limb. At this time we terminate the MM#003 Major Flare Watch, although the target stays as NOAA 13796. More C-class flares are expected in the next 24 hours, with a chance for a low M-class flare. The position of NOAA 13796 on 28-Aug-2024 at 15:30 UT is: S04W62 , ( 838" , -121" ) 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.

MM#003 Major Flare Watch
by Max Millennium Chief Observer 27 Aug '24

27 Aug '24

Dear Collaborators, The level of solar activity is moderate. Target region NOAA 13796 was confirmed as having grown in spot area since the last message, continuing to be classified as a beta-gamma/D-type sunspot group. NOAA 13796 have remained the most flare-productive region on disk, being the source of two C-class flares and the only M-class flare in the period - an M1.1 on 27-Aug-2024 at 09:30 UT. The current MM#003 Major Flare Watch will continue on NOAA 13796 for the next 24 hours. C-class activity is expected over the following 24-hour period, with a strong chance for additional M-class flares. The position of NOAA 13796 on 27-Aug-2024 at 19:30 UT is: S04W52 , ( 748" , -138" ) 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.

26 Aug '24

Dear Collaborators, Solar activity is at a moderate level. Target region NOAA 13800 has retained a beta-gamma/E-type sunspot group classification, but some of its intermediate spot distribution has simplified. NOAA 13800 has only produced three C-class flares in the period, the largest being a C6.6 flare on 25-Aug-2024 at 17:23 UT. The previous target NOAA 13796 also evolved somewhat, retaining its classification as a beta-gamma/D-type sunspot group but showing some flux emergence in its intermediate spots late in the period. NOAA 13796 has increased in flare productivity, being the source of several C-class flares and the largest magnitude flare since the last message - an M1.4 on 26-Aug-2024 at 11:28 UT. The MM#003 Major Flare Watch will remain in effect, but the target switches to NOAA 13796 for the following 24 hour period. C-class activity is expected in the next 24 hours, with a good chance for further M-class activity. The position of NOAA 13796 on 26-Aug-2024 at 19:30 UT is: S04W38 , ( 584" , -158" ) 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.

MM#003 Major Flare Watch
by Max Millennium Chief Observer 25 Aug '24

25 Aug '24

Dear Collaborators, Solar activity remains at a moderate level. NOAA 13800 produced several flares, the largest being an M1.7 at 23:18 UT yesterday. NOAA 13800 remains classified as a beta-gamma region and has a relatively small area. However, this region still shows some signs of sunspot dynamism. The Major Flare Watch will be extended for what may be a final 24 hours. Further C-class activity is expected, with a chance for additional M-class activity in the next 24 hours. The position of NOAA 13800 on 25-August-2024 at 11:30 UT is: S28W02, (29",-546") 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.

MM#003 Major Flare Watch
by Max Millennium Chief Observer 24 Aug '24

24 Aug '24

Dear Collaborators, Solar activity has continued at a moderate level since the last message. A number of flares were produced over the last 24 hours, the largest being an M5.1 from NOAA 13800 at 20:08 UT yesterday. NOAA 13796 has remained relatively quiet since the last message, producing an M1.6 at 00:02 UT today. NOAA 13800 has been newly classified as a beta-gamma type region. The Major Flare Watch will be extended and the target region will switch to NOAA 13800 as this region has produced a number of M-class flares in the last 24 hours. Further M-class activity is possible with a chance for an additional >M5 event in the next 24 hours. The position of NOAA 13800 on 24-August-2024 at 07:30 UT is: S28E10, (-145",-544") 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.

MM#003 Major Flare Watch
by Max Millennium Chief Observer 23 Aug '24

23 Aug '24

Dear Collaborators, Solar activity remains at a moderate-high level. Several flares were produced since the last message, the largest being an M3.5 from a newly numbered active region, NOAA 13801 at 03:31 UT today. NOAA 13796 remains classified as a beta-gamma type region but has shown a slight reduction in area. The Major Flare Watch will be extended for now with NOAA 13796 as the target region, attention should also be paid to NOAA 13801 as it develops further. Further C-class activity is expected, with a slight chance for an isolated >M5 event in the next 24-48 hours. The position of NOAA 13796 on 23-August-2024 at 07:30 UT is: S02E08, (-132",-147") 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.

22 Aug '24

Dear Collaborators, Solar activity has slightly increased since the last message. Several flares were produced over the last 24 hours, the largest being an M5.1 from NOAA 13796 at 21:59 UT yesterday. NOAA 13796 is currently classified as a beta-gamma region with an area of 350 μh. At this time we are initiating a Major Flare Watch with NOAA 13796 as the target region. Further C- and M-class activity is expected with a chance for an additional >M5 flare in the next 24-48 hours. The position of NOAA 13796 on 22-August-2024 at 11:30 UT is: S03E19, (-309",-158") 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.
