MM#009 Default Target
by Max Millennium Chief Observer 16 Jun '26

16 Jun '26

Dear Collaborators, Solar activity has been very low since the last message. The largest event in the period was a C1.9 flare at 18:46 UT yesterday(6/15) from the Northeast limb region yet unnumbered. This region also produced a few additional high-B to low-C class flares in the past 24 hours and has begun to progress onto the solar disk. Yesterday's target, NOAA 14465 has now been re-classified as a beta-gamma type, but has been flare-quiet, after a C1.8 flare at 13:12 UT yesterday. Today we will switch the default target to the unnumbered region rotated from the Northeast limb, because of the recent flare history. Additional high-B to low-C flares are expected. The position of the target on 16-Jun-2026 at 15:30 UT is: N07E74 (-902", 110").

Dear Collaborators, Solar activity remains low since the last message. Two C1.7 events are the largest in the period; one at 01:50 UT today(6/15) from the target region, NOAA 14464 and the other at 09:48 UT today from the region behind the Northeast limb (~N08 deg). NOAA 14464 is showing sign of decay losing trailing sunspots, while the Northeast limb region has produced a few more low-C class activities in the past several hours. NOAA 14465 (N07W18) has been undergoing flux emergence since yesterday; new spots were added in its Southeast and also Northwest vicinities. Although currently no flare is reported from NOAA 14465, these new spots are occasionally showing brightening. Today, we will switch the default target from NOAA 14464 to NOAA 14465 to keep track of these flux emergence, until the Northeast limb region rotates to Earth-view. In the next 24 hours, we will observe NOAA 14465 at the Southeast side of the main sunspot expecting C-class events. The position of the target in NOAA 14465 on 15-Jun-2026 at 16:00 UT is: N06W16 (272", 92").

Dear Collaborators, Solar activity has continued at a low level. The largest event was a C2.5 flare at 12:40 UT yesterday from a plage region located at S21W82. Additionally, NOAA 14462 (N16W83) produced two C1.0 flares and a B6.8 flare, while NOAA 14466 (N06W81) produced a B8.2 flare and a C1.5 flare. However, these three regions have rotated nearly beyond the west limb. The target region, NOAA 14464, produced a B9.1 flare at 10:40 UT today and still retains a beta/D-type sunspot group. Therefore, today the target will remain at 14464. Low-C flares are probable over the following 24 hours. The position of NOAA 14464 on 14-Jun-2026 at 11:30 UT is: S13W51 (716", -222") 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 dropped to a low level. An unnumbered region near the southeast limb (S05E80) produced the largest event, a C1.9 flare at 18:42 UT yesterday, and a C1.0 flare. NOAA 14464 produced a C1.8 flare at 02:00 UT today and two ~C1 flares. This region has been classified as a beta/D-type sunspot group. Yesterday’s target, NOAA 14465 (beta/C-type, N09E07), only produced a C1.4 flare. Today, the target will switch from 14465 to 14464. Additional low-C flares are probable over the following 24 hours. The position of NOAA 14464 on 13-Jun-2026 at 11:30 UT is: S13W36 (542", -223") 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 an intermediate level. The target region NOAA 14465 produced two ~C1 flares, with the largest being a C5.2 flare at 02:04 UT today. Although this region retains a beta-gamma/D-type classification, it has begun to show magnetic signs of fragmentation and decay. Today, the target will remain with 14465, considering its magnetic complexity and prior flaring history. Note that an unnumbered region (S09E89) was also the source of three ~C1 flares. More low-C flares are expected over the next 24 hours. The position of NOAA 14465 on 12-Jun-2026 at 11:30 UT is: N09E23 (-365", 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.

Dear Collaborators, Solar activity has reached an intermediate level in the past 24 hours. The largest event was a C9.0 flare at 08:22 UT today from the target region NOAA 14465. This region has retained its high productivity and a beta-gamma/D-type magnetic configuration, with a further emergence of new spots. Today, the target will continue on 14465. In addition, NOAA 14456 (beta/E-type, N18W91) also produced six ~B8-C6 flares before it completely rotated out of Earth-view. Further C-class flares are expected with a chance for an isolated low-M flare in the following 24 hours. The position of NOAA 14465 on 11-Jun-2026 at 11:30 UT is: N09E33 (-510",140") 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 a low level. The target region NOAA 14465 produced four low-C flares, with the largest magnitude being a C2.6 at 00:51 UT today. This region has increased in magnetic complexity to a beta-gamma/D-type, with its further development. Today, the target should remain at 14465. Note that a newly-emerged region, NOAA 14466 (beta/B-type, N06W23), also produced three ~C1-C2 flares. Additional C-class flares are expected in the coming 24 hours. The position of NOAA 14465 on 10-Jun-2026 at 11:30 UT is: N09E47 (-684", 143") 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 dropped to a low level since the last message. The target region has remained highly productive, producing ten low-C flares, the largest of which was a C4.5 at 04:16 UT today. This region has been designated as 14465 and classified as a beta/D-type sunspot group, displaying separation of its main spots as well as the emergence of new spots. Today, NOAA 14465 shall continue to be the target. More C-class flares are expected in the following 24 hours. The position of NOAA 14465 on 9-Jun-2026 at 11:30 UT is: N11E63 (-827", 178") 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 an intermediate level. The largest event was a C7.2 flare at 02:36 UT today from an unnumbered region near the northeast limb. This region also produced seven low-C flares and became the most productive. Today, this limb region should become the new target. Yesterday’s target, NOAA 14456 has been flare-quiet in this period. Further C-class activity is expected in the next 24 hours. The approximate position of the target on 8-Jun-2026 at 11:30 UT is: N09E84 (-900", 150") 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 low level since the last message. The largest event during the period was a C3.3 flare at 04:10 UT today from the target region NOAA 14456 (N18W41), which also produced seven low C-class flares in the period. 14456 has developed into a beta-gamma-delta magnetic configuration and continues to show significant magnetic flux emergence. Today, the target region will remain NOAA 14456. Further C-class activity is expected, with a chance of low M-class activity in the next 24 hours. The position of NOAA 14456 on 7-Jun-2026 at 11:30 UT is: N18W41, (591", 292") 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.
