31 Jul '26

Dear Collaborators, Solar activity has increased to a low-to-moderate level since the last message. Yesterday's target region NOAA 14498 produced only a C3.1 flare during the period. The largest event was an M1.9 flare at 15:53 UT yesterday from NOAA 14492 near the west limb. NOAA 14499 (N04W02) produced six low C-class flares during the period, including a C3.9 flare. This region has developed into a beta-gamma-delta magnetic configuration, with increases in both sunspot area and spot number. Today the target region will switch to NOAA 14499. Further C-class activity is expected, with a chance of additional low-level M-class activity in the next 24 hours. The approximate position of NOAA 14499 on 31-Jul-2026 at 11:30 UT is: N04W02 (34", 67") 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 since the last message. The largest event during the period was a C3.9 flare at 05:44 UT today from the target region NOAA 14498 (N14E43). 14498 has developed into a beta-gamma magnetic configuration and produced several other low C-class flares during the period. The area east of its main sunspot shows clear signs of magnetic flux emergence and mixed polarities. Therefore, today we will continue to watch NOAA 14498 as the target region. The emerging region mentioned yesterday has now been designated NOAA 14500 (N18E51, beta/C-type). This region also produced a few low C-class flares during the period. If possible, please also include 14500 in your 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 14498 on 30-Jul-2026 at 11:30 UT is: N14E43 (-627", 162") 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 to a low level since the last message. Yesterday's target region, NOAA 14494 (S03W35, beta/C-type), produced no significant flares and continued to weaken. The largest event during the period was a C1.9 flare at 05:31 UT today from NOAA 14498 (N14E55, beta/C-type). This region also produced several other low C-class flares and has developed rapidly, with increases in both sunspot area and spot number. 14498 is showing dynamic sunspot activity, and a new active region is emerging to its northeast. Today, the target region will switch to NOAA 14498. If possible, please also include the emerging region northeast of 14498 in your 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 14498 on 29-Jul-2026 at 11:30 UT is: N14E55 (-752", 176") 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 to a moderate-to-low level since the last message. The largest event during the period was a C5.2 flare at 03:08 UT today from the target region NOAA 14494 (S04W21, alpha/H-type). This region also produced several other C-class flares during the period, including C3.6 and C3.5 events, but has continued to decay, decreasing in both sunspot number and sunspot area. NOAA 14492 (N16W42) is currently classified as a beta-gamma-delta region but did not produce any significant flares during the period. Today we will continue to watch NOAA 14494 as the target region. 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 14494 on 28-Jul-2026 at 11:30 UT is: S04W21 (339", -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 increased to a moderate level since the last message. Yesterday's target region, NOAA 14493 (N05W80), produced only a C1.6 flare during the period and is approaching the western limb. The largest event during the period was an M3.2 flare at 15:17 UT yesterday from NOAA 14494 (S04W09), followed by an M1.0 flare at 02:32 UT today. Both M-class flares occurred on the western side of the leading sunspot in NOAA 14494. Today, the target will switch to NOAA 14494, although this region has lost its delta configuration and is showing some decay. NOAA 14495 (S02W20, beta/D-type), located near NOAA 14494, also produced several C-class flares during the period, including a C4.2 flare. If possible, please also include this region in your field of view. Further C-class activity is expected, with a chance of additional low-level M-class activity in the next 24 hours. The position of NOAA 14494 on 27 July 2026 at 11:30 UT is: S04W09 (148", -153") 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 remains at a low level. The largest flare produced in the last 24 hours was a C4.2 from newly numbered active region NOAA 14495 at 07:25 UT today. NOAA 14493 has remained relatively quiet since the last message as it nears the western limb. Additionally, NOAA 14494 has remained quiet, however this region is in proximity to NOAA 14495 and may show further development. NOAA 14493 will remain the target region for what may be the last 24 hours while it is still fully in view. Further C-class activity is expected. The position of NOAA 14493 on 26-July-2026 at 07:30 UT is: N05W63, (839", 42") 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 continues at a low level. A small number of flares were produced since the last message, the largest being a C3.0 from NOAA 14493 at 21:46 UT yesterday. NOAA 14493 is now classified as a beta-gamma region. Activity across the disk remains low. NOAA 14493 has begun its approach of the western limb and the region will continue to be monitored as it transits the solar limb. NOAA 14494 appears to show a growth in emerging flux but has remained relatively quiet. NOAA 14493 remains the target region. Further C-class activity is expected. The position of NOAA 14493 on 25-July-2026 at 11:30 UT is: N05W53, (753", 30") 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 remains low. A number of flares were produced since the last message, the largest being a C2.8 attributed to a currently unnumbered active region in the southeastern portion of the disk at 13:29 UT yesterday. NOAA 14493 has now been reclassified as a beta-gamma-delta type region and NOAA 14494 has also been upgraded to a beta-delta type region. However, these two regions have remained relatively quiet since the last message. For now, NOAA 14493 will continue as the target region. Further C-class activity is expected. The position of NOAA 14493 on 24-July-2026 at 11:30 UT is: N06W39, (592", 32") 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 continues at a low level. Several flares were produced, the largest being a C5.4 at 18:42 UT yesterday from NOAA 14493. This region has now reduced in complexity and is currently classified as a beta-gamma type region. While the overall spot size of the region has continued to increase, the emerging flux from this region appears to have reduced. At this time, we are ending the major flare watch, NOAA 14493 will remain as the target region. Further C-class activity is expected. The position of NOAA 14493 on 23-July-2026 at 11:30 UT is: N05W26, (413", 7") 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 22 Jul '26

22 Jul '26

Dear Collaborators, Solar activity has persisted at a low to moderate level. Multiple flares have been produced since the last message, the largest being an M3.6 from NOAA 14493 at 06:27 UT today. NOAA 14493 remains highly productive, retaining its beta-gamma-delta classification and more than doubling in size. While we are yet to see a major flare from this region, the high level of flux and sunspot dynamism warrants the continuation of the major flare watch campaign. The major flare watch will remain active for the next 24 hours. Further C- and low M-class activity is likely with a slight chance for an isolated >M5.0 event. The position of NOAA 14493 on 22-July-2026 at 11:30 UT is: N05W12, (196", 1") 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.
