MM#009 Default Target
by Max Millennium Chief Observer 13 Sep '26

13 Sep '26

Dear Collaborators, Solar activity has remained at low levels since the last message. Yesterday's target region, NOAA 14530 (N19W56, beta/D-type), produced four B-class flares, including a B9.7 at 23:19 UT yesterday, but its sunspots appear to be decaying. The largest event during the period was a C5.8 flare at 17:09 UT yesterday, attributed to NOAA 14521 (N09W91, alpha/H-type), which is now just beyond the west limb. NOAA 14529 (N12W25, beta/C-type) is showing clear signs of magnetic flux emergence around its leading sunspot. Today, the target region will switch to NOAA 14529. C-class activity remains possible in the next 24 hours. The position of NOAA 14529 on September 13 at 11:30 UT is: N12W25 (395", 90") 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 remained at low levels since the last message, with only B-class flares reported during the period. The largest events were two B8.5 flares at 23:06 UT yesterday and 11:44 UT today from NOAA 14521 (N09W88, alpha/H-type), which is now close to the west limb. The target region NOAA 14530 (N19W44, beta/D-type) produced three B-class flares, including a B7.8 at 11:40 UT today. This region continues to show dynamic sunspot behaviour. Today, the target will remain at NOAA 14530. NOAA 14524 (N12W49, alpha/H-type) also produced two B-class flares during the period, including a B7.8. If possible, please continue to include NOAA 14524 in the field of view. C-class activity remains possible in the next 24 hours. The position of NOAA 14530 on September 12 at 15:30 UT is: N19W44 (627",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.

Dear Collaborators, Solar activity has remained at low levels since the last message. The largest event during the period was a C1.6 flare at 16:53 UT yesterday from the target region NOAA 14530 (N19W28, beta/D- type; see the SSW Latest Events entry <https://www.lmsal.com/solarsoft/latest_events/#C1.6_AR_4530_N16W19_Dimming_…>). This region also produced a few B-class flares during the period, including a B8.1 flare. NOAA 14530 continues to show clear signs of magnetic flux emergence. Therefore, today we will continue to watch NOAA 14530 as the target region. If possible, please continue to include NOAA 14524 in the field of view. Further C-class activity is expected in the next 24 hours. The position of NOAA 14530 on September 11 at 11:30 UT is: N19W28 (424", 208") 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 remained at low levels since the last message. The largest event during the period was a C1.4 flare at 00:25 UT today from NOAA 14524 (N12W20, alpha/H-type), with coronal brightenings indicating magnetic connectivity with the target region NOAA 14530 (N19W14, beta/D-type). Although the magnetic polarities of 14530 remain relatively diffuse, this region is now showing clear signs of magnetic flux emergence. Today, we will continue to watch NOAA 14530 as the target region due to this ongoing flux emergence and its magnetic connectivity with NOAA 14524. If possible, please include NOAA 14524 in the field of view. Further C-class activity is expected in the next 24 hours. The position of NOAA 14530 on September 10 at 11:30 UT is: N19W14 (218", 198") 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 remained at low levels since the last message. The largest events during the period were two C3.4 flares, at 23:22 UT yesterday from NOAA 14528 (S11E31, alpha/H-type) and at 08:48 UT today from NOAA 14524 (N13W07, alpha/H-type). The latter event also involved the target region NOAA 14530 (N19W01, beta/D-type), with bright coronal loops between the two regions. NOAA 14528 produced additional low C-class flares, while NOAA 14521 (N09W47, alpha/H-type) produced several C-class flares, including a C3.2. Today, we will continue to watch NOAA 14530 as the target region due to its increasing sunspot area and its magnetic connectivity with NOAA 14524. If possible, please also include NOAA 14524 in the field of view. Further C-class activity is expected, with only a slight chance of an isolated low M-class flare in the next 24 hours. The position of NOAA 14530 on September 9 at 11:30 UT is: N19W01 (15", 194") 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 remained at low levels since the last message. Yesterday's target region, NOAA 14524 (N12E06), has been flare-quiet and has been downgraded to an alpha/H-type region, with decreases in both sunspot area and spot number. The largest event during the period was a C2.5 flare at 12:19 UT today from NOAA 14521 (N09W34, alpha/H-type). The newly numbered region NOAA 14530 (N19E12, beta/D-type), northeast of 14524, is showing clear signs of magnetic flux emergence. Today, the target region will switch to NOAA 14530. Further C-class activity is expected, with only a slight chance of an isolated low M-class flare in the next 24 hours. The position of NOAA 14530 on September 8 at 11:30 UT is: N19E12 (-187", 197") 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.
