MM#009 Default Target (corrected target coordinates)
by Max Millennium Chief Observer 29 Jun '24

29 Jun '24

Dear Collaborators, *** CORRECTED TARGET COORDINATES *** Solar activity is at a low level. Target region NOAA 13723 has continued to decay further in sunspot area and number of spots since the last message, losing its magnetic polarity mixing to be classified as a beta/C-type sunspot group. Once again, only C-class flares have occurred in the period, with NOAA 12723 again producing one (a C2.3 flare on 28-Jun-2024 at 18:36 UT) while the largest magnitude flare in the period was a C5.9 on 29-Jun-2024 at 15:32 UT attributed to a currently unnumbered region. Additional C-class activity is expected in the next 24 hours, with a small chance for an isolated M-class flare. The position of NOAA 13723 on 29-Jun-2024 at 19:30 UT is: S20W04 , ( 62", -366" ) 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, The level of solar activity is low. Target region NOAA 13723 continued to decay in sunspot area and number of spots since the last message and was confirmed as having lost its delta spot configuration to be classified as a beta-gamma/D-type sunspot group. Only C-class flares have been observed in the period, with NOAA 12723 producing one (a C2.7 on 27-Jun-2024 at 21:36 UT) while the largest magnitude flare in the period was a C6.6 on 27-Jun-2024 at 23:38 UT attributed to newly numbered NOAA 13730 (a beta/B-type sunspot group). However, it is worth noting that NOAA 13730 is located just West of 13723 and the flare occurred between the two. At this point the MM#003 Major Flare Watch ceases, although NOAA 13723 will remain as the default target region. More C-class flares are expected over the following 24-hour period, with a small chance for an isolated low M-class flare. The position of NOAA 13723 on 28-Jun-2024 at 15:30 UT is: S19E12 , ( -186", -348" ) 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 26 Jun '24

26 Jun '24

Dear Collaborators, The level of solar activity is low. The target region NOAA 13723 grew slightly in sunspot area and number of spots since the last message and was reclassified as a beta-gamma-delta/F-type sunspot group, but it now appears to be starting to decay. Only C-class flares have been observed in the period, the largest of which was a C6.2 on 26-Jun-2024 at 14:42 UT from newly numbered NOAA 13728, a beta/B-type sunspot group that is trailing immediately behind NOAA 13723. The MM#003 Major Flare Watch continues for a possibly final 24 hours with NOAA 13723 as the target, again maintaining focus towards its rear spots (i.e. close to NOAA 13728). C-class flares are expected over the following 24-hour period, with a chance for an isolated mid-to-high M-class flare. The position of NOAA 13723 on 26-Jun-2024 at 19:30 UT is: S19E33 , ( -487", -339" ) 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 25 Jun '24

25 Jun '24

Dear Collaborators, Solar activity is at a moderate level. The target region NOAA 13723 remained stable in terms of sunspot area and number of spots and has remained classified as a beta/D-type sunspot group. The solar flare history of all active regions has been compromised from 24-Jun-2024 at 21:25 UT until 25-Jun-2024 at 12:00 UT because of network outage at Space Weather Prediction Center (SWPC) that provides operational access to the GOES X-ray time series data. Target region NOAA 13723 produced a C7.9 flare on 24-Jun-2024 at 17:01 UT and an M1.0 flare occurred from the spots trailing immediately behind NOAA 13723. The largest magnitude flare in the period (an M1.1 flare on 24-Jun-2024 at 19:02 UT) came from the limb-exiting location of previous region NOAA 13713. The MM#003 Major Flare Watch continues for a further 24 hours with NOAA 13723 as the target, with a focus towards its rear spots. Low M-class flares are likely in the next 24 hours, with a chance for a mid-to-high M-class flare. The position of NOAA 13723 on 25-Jun-2024 at 15:30 UT is: S19E45 , ( -632", -333" ) 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 24 Jun '24

24 Jun '24

Dear Collaborators, The level of solar activity is moderate. Yesterday's target region has now been designated as NOAA 13723, and was classified as a beta/D-type sunspot group. This region was still located significantly towards the East limb at the start of the UT day, so this classification might not be totally accurate. NOAA 13723 produced two C-class flares since the last message, with some low M-class activity produced by NOAA regions 13712 (beyond the South West limb) and 13713 (at the South West limb). The MM#003 Major Flare Watch will continue for another 24 hours with NOAA 13723 as the target while its development is tracked. Additional high C-class flares are expected over the following 24-hour period, with a chance for another M-class flare. The position of NOAA 13723 on 24-Jun-2024 at 15:30 UT is: S18E58 , ( -762", -310" ) 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 23 Jun '24

23 Jun '24

Dear Collaborators, Solar activity has increased significantly since the last message. The largest event was an M9.3 flare at 12:51 UT today produced by a southeast limb region (unnumbered yet). At this time we are implementing the Major Flare Watch campaign on this limb region that is rotating onto the visible solar disk. It should be mentioned that NOAA 13712 and 13716 produced an M1.3 and an M2.4 flare respectively in the period, both of which are rotating over the west limb. Additional low M-class activities are expected with a chance of an isolated >M5 flare in the next 24 hours. The approximate position of the target on June 23 at 15:30 UT is: S19E75 (-900", -300") 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 was at a moderate level in the past 24 hours. The largest event was an M2.9 flare at 08:43 UT on June 22 produced by NOAA 13716 (N10W73) that has a beta-gamma/ E-type configuration. NOAA 13720 (S05E35, beta/C-type) and a southeast limb region (S19E89) also produced two ~M1.0 flares. The target regions of NOAA 13713 (beta-gamma-delta/E-type) and 13712 (beta-gamma) produced five high C-class flares during the period. Today we continue to watch these two regions for a final 24 hours as they rotate over the west limb. C-class activities are expected with a chance of a low M-class flare in the next 24 hours probably from various regions. The position of NOAA 13713 on June 22 at 23:30 UT is: S14W67 (844", -240") 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-to-low level since the last message. The largest event during the period was an M5.8 flare at 23:00 UT on June 20 produced by NOAA 13719 (S13E41) that has a beta/D-type sunspot group. This region then was flare quiet. Yesterday's target(s) NOAA 13712 (and 13713) produced about nine C-class flares. 13712 and 13713 retained a beta-gamma-delta/ E-type configuration but 13712 began to decay. Today we will watch NOAA 13713 but please also include 13712 (S24W66) in the field of view if possible. C-class activities are expected with some chance of an M-class flare in the next 24 hours. The position of NOAA 13713 on June 21 at 23:30 UT is: S14W53 (733", -246") 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 was at a moderate level in the past 24 hours. The largest event was an M1.1 flare at 15:09 UT today produced by NOAA 13719 (S12E56) that has a beta/C-type configuration. 13719 and some other regions, 13716 (N10W44, beta-gamma/ D-type) and 13720 (S04E65, beta/D-type), also produced a few C-class flares. The target region(s) 13712 (and 13713) only produced two C-class flares during the period. Both 13712 and 13713 (S15W39) have a beta-gamma-delta/E-type configuration. Today we continue to watch 13712 and also 13713 if possible. C-class activities are expected with a chance of low M-class flare in the next 24 hours. The position of NOAA 13712 on June 20 at 19:30 UT is: S24W50 (662", -401") 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.
