MM#003 Major Flare Watch
by Max Millennium Chief Observer 18 Jul '24

18 Jul '24

Dear Collaborators, Solar activity has decreased to a moderate level in the past 24 hours. There are two active regions (NOAA 13751, 13753) that produced four low-M flares. NOAA 13751 (beta-gamma/E-type, S08E20) was a source of two largest flares (including an M2.2 at 10:04 UT and an M2.0 at 10:20 UT today), with an emergence of new magnetic fluxes. NOAA 13753 (beta/C-type, N11W57) produced an M1.2 flare and an M2.0 flare yesterday but it shows magnetic signs of decay. Although the limb target NOAA 13738 was flare quiet in the period, its looptop shall remain the target with the Major Flare Watch before disappearing from Earth-view. More low-M activity is probable with a slight chance of a >M5 flare in the following 24-hour period. The approximate position of NOAA 13738 at 11:30 UT on 18-Jul-2024 is: N09W90 (932", 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.

Dear Collaborators, Solar activity has decreased slightly in the past 24 hours. The limb target region NOAA 13738 produced an M1.2 flare at 09:26 today. Today we will continue the Major Flare Watch for another 24 hours, due to the complex beta-gamma-delta/F-type magnetic configuration, sunspot area of >1000 MSH, and past flaring history in this region. Besides, some other active regions (NOAA 13753, 13744, 13743) also produced several M-class flares, including the largest magnitude being an M5.1 at 06:26 today from NOAA 13743 (beta/E-type, S11W37). More low-M activities are very likely with a chance of an isolated >M5 flare in the next 24 hours. The position of NOAA 13738 at 11:30 UT on 17-Jul-2024 is: N09W90 (932", 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.

Dear Collaborators, Yesterday's Target NOAA 13738 just produced an X1.9 flare (at 13:11 UT) when it was rotating over the west limb. This region retains a complex beta-gamma-delta/F-type configuration though it seems to enter the decay phase. The Major-Flare-Watch target will switch back to 13738 for the next 24 hours. M-class activities are expected with a chance of a major (>M5) flare (perhaps occulted) in the following 24-hour period. The position of NOAA 13738 on July 16 at 11:30 UT is: S09W75 (901", -166") 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 moderate level in the past 24 hours. The largest event since the last message was an M3.6 flare at 07:24 UT today produced by NOAA 13753 (beta/D-type, N12W29), a newly-emerged region. NOAA 13744 (beta/C-type, N16W08) also produced an M1.4 flare and a C7.3 flare but it shows signs of decay. NOAA 13751 became the most productive region in the period and produced four high C-class flares including the largest magnitude being a C9.4 flare at 22:23 UT yesterday. This region has been classified as a beta-gamma/D-type magnetic configuration, with new negative magnetic fluxes emerging in its following portion. It also shows a high and increasing current helicity. Today the Major Flare Watch region will switch to NOAA 13751 from NOAA 13738. Yesterday’s target (13738) was flare-quiet in the period. Further C-class flares are expected with additional low-M activity probable in the following 24 hours from various active regions. The position of NOAA 13751 at 11:30 UT on 16-Jul-2024 is: S08E47 (-685", -181") 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 since the last message. The target region NOAA 13738 has been still the most productive in the period. This region was a source of six M-class and numerous C-class flares, with the largest being an M3.0 at 04:05 UT yesterday and an M2.7 at 09:21 UT today. NOAA 13738 has grown in terms of sunspot area by consolidating some spots and it remains a beta-gamma-delta/F-type sunspot group. 13738 shall remain the target with the Major Flare Watch in effect. Further low-M flares are expected, with a chance of an above-M5 flare in the next 24-48 hours. The position of NOAA 13738 at 11:30 UT on 15-Jul-2024 is: S09W60 (808", -183") 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 a high level since the last message. The target region NOAA 13738 produced an X1.5 flare an hour ago (at 02:23 UT) and also six M-class flares (including an M5.3 at 12:21 UT and an M5.0 at 22:44 UT yesterday). 13738 has been designated as a beta-gamma-delta/F-type configuration with a sunspot area of 1100 MSH. At this time we implement the Major Flare Watch campaign on this region. Additional M- class activities are expected with a good chance of >M5 flare in the next 24 hours. The approximate position of NOAA 13738 on July 14 at 00:00 UT is: S09W40 (600", -200") 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#009 Default Target

Dear Collaborators, Solar activity has been at a moderate level since the last message. The target region NOAA 13738 produced the largest magnitude flare, an M1.4 at 02:55 UT today. It also produced five C-class flares including a C9.6. This region retains a beta-gamma/F-type configuration with increasing the sunspot area further. Note that a southeast limb region (S08E89) produced two occulted C8.0 flares. Additional C-class activities are expected with a good chance of some low M-class flares in the next 24-48 hours. The position of NOAA 13738 on July 13 at 11:30 UT is: S09W33 (509", -205") 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.

12 Jul '24

Dear Collaborators, Solar activity was at a low level in the past 24 hours. The largest event was a C6.5 flare peaking at 13:28 UT today produced by the target region NOAA 13738 (and also 13743?). 13738 retains a beta-gamma/F-type configuration and produced more than ten C-class flares. Further C-class activities are expected with some chance of a low M-class flare in the next 24 hours. The position of NOAA 13738 on July 12 at 15:30 UT is: S08W22 (351", -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.

MM#009 Default Target

Dear Collaborators, Solar activity was at a moderate level in the past 24 hours. The largest event since the last message was an M1.3 flare at 04:03 UT produced by a newly numbered region NOAA 13745 (S17E51, beta/C-type). The target region produced two M1 flares (M1.0 and M1.2) and more than 10 C-class flares (including a C9.7) during the period. 13738 has been designated as a beta-gamma/F-type configuration with increasing in the sunspot area and number of spots significantly. Additional low M-class flares are expected in the next 24 hours. The position of NOAA 13738 on July 11 at 11:30 UT is: S10W06 (97", -228") 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 a moderate level since the last message. NOAA 13738 produced four M-class flares (M1.5, M1.3, M1.4, and M1.2) and 10 C-class flares today. This region retains a beta-gamma/ E-type configuration but increases the number of spots significantly. Today the target will switch back to this region. Yesterday's limb target was designated as NOAA 13742 and only produced a C3.0 flare during the period. Further C-class activities are expected with a good chance of low M-class flares in the next 24 hours. The position of NOAA 13738 on July 10 at 11:30 UT is: S10E08 (-129", -226") 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.
