MM#003 Major Flare Watch
by Max Millennium Chief Observer 05 Jul '26

05 Jul '26

Dear Collaborators, Solar activity has been at a high level. The target region NOAA 14479 was the source of 11 low M-class plus 6 C-class flares over the past 24 hours, the largest ones being two M3.2 flares. Please note that the largest flare during the period was an X1.1 flare at 07/04/20:29 UT produced by a newly numbered region NOAA 14482 (S08E75), which is still at the southeast limb. Today we will continue to watch NOAA 14479 for a final 24 hours as it is rotating over the west limb. Low M-class activities are expected with a good chance of major flares from NOAA 14479 and 14482 in the following 24 hours. The position of NOAA 14479 on July 5 at 03:30 UT is: N16W81 (896", 251") See http://www.SolarMonitor.org <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 to high level. The largest event since the last message was an M6.7 flare at 07/03/17:49 UT produced by the target region NOAA 14479. 14479 was also the source of six low M-class flares plus seven C-class flares. Please note that another region NOAA 14478 (S06W48, downgraded to a beta-gamma/F-type configuration) produced the second largest flare, an M6.3 flare at 07/03/18:57 UT. Today we continue to watch NOAA 14479 which has a beta-gamma-delta/F-type sunspot group. Further low M-class activities are expected with a chance of some major flare in the following days. The position of NOAA 14479 on July 4 at 03:30 UT is: N17W68 (837", 257") See http://www.SolarMonitor.org <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. An M2.8 (at 07/02/10:21 UT) and an M1.2 (at 07/02/23:03 UT) flares were produced by NOAA 14480 (S16W60, beta-gamma/E-type) and the target region NOAA 14479, respectively. NOAA 14479 also produced six C-class flares during the period. It retains a beta-gamma-delta/E-type configuration. Today we will continue the Major Flare campaign on NOAA 14479. Additional low M-class flares are expected with some chance of an isolated major flare above M5.0 in the coming days. The position of NOAA 14479 on July 3 at 07:30 UT is: N17W56 (749", 248") See http://www.SolarMonitor.org <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 relatively high level. The largest event since the last message was an M8.5 flare at 07/01/22:57 UT, produced by NOAA 14478, which retains a beta-gamma-delta/F-type configuration. 14478 also produced an M1.1 flare. The target region NOAA 14479 retains a beta-gamma-delta/E-type sunspot group and produced three low M-class flares (the largest one being an M4.2 flare) plus three C-class flares during the period. Today we will continue to watch NOAA 14479. Further low M-class flares are expected with a chance of major flares above M5.0 from both regions. The position of NOAA 14479 on July 2 at 07:30 UT is: N17W42 (605", 241") See http://www.SolarMonitor.org <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 for the past 24 hours. The largest event was an X1.5 flare at 06/30/20:34 UT produced by NOAA 14479. NOAA 14479 was also the source of eight low M-class flares. It retains a complex beta-gamma-delta/E-type configuration. Today we will continue the Major Flare campaign but switch the target to NOAA 14479. Yesterday's target NOAA 14475 only produced three C-class flares during the period. Further M-class flares are expected with a chance of an X-class flare in the next few days. The position of NOAA 14479 on July 1 at 15:30 UT is: N16W33 (495", 221") See http://www.SolarMonitor.org <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 significantly increased since the last message. An M5.9 flare was produced by NOAA 14475 at 12:37 UT today. This region also produced an M1.3 flare and nine C-class flares. Today we will implement a Major Flare Watch campaign on NOAA 14475. It has been designated as a complex beta-gamma-delta/D-type region. Please note that NOAA 14479 (N16W19) produced an M1.4 flare and has developed to a beta-gamma-delta/E-type configuration. Additional low M-class flares are expected with a chance of another major flare (>M5) in the next few days. The position of NOAA 14475 on June 30 at 15:30 UT is: S09W58 (792", -171") See http://www.SolarMonitor.org <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 largest event in the past 24 hours was a C9.5 flare at 06/28/21:17 UT produced by NOAA 14475 (S10W40) which has a beta-gamma/D-type configuration. The most productive region during the period was NOAA 14479 (N16W05, beta/D-type). It produced more than ten C-class flares, the largest one being a C8.7 flare. The target region NOAA 14478 only produced a C2.7 and a C4.2 flares over the past 24 hours, but it is still showing an increased current helicity and retains its beta-gamma-delta/F-type configuration. Today we will continue to watch this region. Further C-class activities are expected from various regions with some chance of an isolated low M-class flare in the next few days. The position of NOAA 14478 on June 29 at 11:30 UT is: S06E13 (-211", -141") See http://www.SolarMonitor.org <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 since the last message. The largest event during the period was a C7.5 flare at 21:06 UT yesterday from NOAA 14475 (S10W26, beta-gamma/D-type). NOAA 14475 became the most flare-productive region during the period, producing five additional low C-class flares. The target region NOAA 14478 (S06E26, beta-gamma- delta/F-type) produced only a C2.1 flare but remains the largest and most magnetically complex region on the visible disk. Today, the target region will remain NOAA 14478, as it is showing ongoing significant flux emergence. Further C-class activity is expected, with a slight chance of an isolated low M-class flare in the next 24 hours. The position of NOAA 14478 on 28-Jun-2026 11:30 UT is: S06E26 (-412", -136") 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 since the last message. The largest event during the period was a C3.9 flare at 09:08 UT today from NOAA 14475 (S09W13, beta-gamma/D-type), which also produced a C3.1 flare later in the period. The target region NOAA 14478 (S06E39, beta-gamma-delta/F-type) produced several low C-class flares and remains the largest and most magnetically complex region on the visible disk. Continued significant flux emergence is still visible in NOAA 14478, especially in its central part. Today, we will continue with NOAA 14478 as the target region. Further C-class activity is expected, with a chance of an isolated low M-class flare in the next 24 hours. The position of NOAA 14478 on 27-Jun-2026 11:30 UT is: S06E39 (-592", -130") 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 slightly increased since the last message. The largest event during the period was a C6.6 flare at 14:53 UT yesterday from the target region NOAA 14478 (S06E56). 14478 has increased in magnetic complexity to a beta-gamma-delta configuration and produced several additional C-class flares in the period, including C5.8 and C5.0 events. Today, we will continue with NOAA 14478 as the target region, as it is showing significant magnetic flux emergence. Further C-class activity is expected, with a chance of an isolated low M-class flare in the next 24 hours. The position of NOAA 14478 on 26-Jun-2026 11:30 UT is: S06E56 (-779", -120") 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.
