MM#003 Major Flare Watch
by Max Millennium Chief Observer 31 May '24

31 May '24

Dear Collaborators, Solar activity has slightly diminished since the last message. A number of flares were produced in the last 24 hours, the largest being an M1.0 at 11:06 UT today from NOAA 13697. This region continues to show signs of emerging flux and some limited signs of dynamic sunspot behaviour. The Major Flare Watch will be extended for a further 24 hours with NOAA 13697 as the target region. Further C- and M-class activity is expected, with a slight chance for an isolated >M5 flare. The position of NOAA 13697 on 31-May-2024 at 11:30 UT is: S18E42, (-603",-284") 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

Dear Collaborators, Solar activity remains at an intermediate level. A number of flares were produced in the last 24 hours, including an X1.4 from NOAA 13697 at 14:11 UT yesterday. Additionally, an M5.7 was produced from NOAA 13691 at 18:32 UT yesterday. NOAA 13697 is now classified as a beta-gamma-delta type region with an approximate area of 400 μh. The Major Flare Watch will continue with NOAA 13697 as the target region. Additional >M5 activity is possible over the next 24-48 hours. The position of NOAA 13697 on 30-May-2024 at 11:30 UT is: S18E49, (-680",-284") 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

Dear Collaborators, Solar activity continues at an intermediate level. The target region has now been numbered as NOAA 13697 and has produced several flares in the last 24 hours, the largest being an M2.6 at 12:45 UT today. Currently, this region is classified as a beta-gamma type region and continues to show signs of significant flux. The Major Flare Watch will be extended for what may be the final 24 hours, while target region NOAA 13697 continues to traverse further onto the solar disk. Further C-class activity is expected with a slight chance for an isolated >M5 event. The position of NOAA 13697 on 29-May-2024 at 11:30 UT is: S18E62, (-796",-285") 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

28 May '24

Dear Collaborators, Solar activity has remained at an intermediate level since the last message. The target region produced several partially-occulted flares, the largest being a C9.0 at 19:09 UT yesterday. The target region is now partly visible on the southeast limb and continues to traverse onto the solar disk, but remains unnumbered. This region also continues to show significant flux and numerous closed loops in the upper solar atmosphere. The Major Flare Watch will continue while the target region moves further onto the solar disk. Isolated >M5 activity is possible in the next 24-48 hours. The approximate position of the target region on 28-May-2024 at 11:30 UT is: S18E81, (-888", -290") 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 27 May '24

27 May '24

Dear Collaborators, Solar activity is at a low-intermediate level. Several flares were produced since the last message, including a partially-occulted X2.9 from a currently unnumbered region behind the southeast limb at 06:49 UT today. It is believed that this region corresponds to the previously numbered active region NOAA 13664 rotating back onto the disk. This region also shows significant flux emergence. At this time we are implementing a Major Flare Watch and the target region will switch to the southeast limb surrounding this active region as it rotates onto the solar disk. Further >M5 activity is possible within the next 24-48 hours. The approximate position of the target region on 27-May-2024 at 11:30 UT is: S18E86, (-899", -291") 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#009 Default Target
by Max Millennium Chief Observer 26 May '24

26 May '24

Dear Collaborators, Solar activity continues at a low level. The largest event since the last message was a C5.3 flare at 09:27 UT today produced by a new numbered region NOAA 13691. This region also produced two low C-class flares. It has been designated as a beta-gamma-delta/D-type configuration and is showing some new flux emergence. This region will become today's target. Yesterday's target 13685 has been steady and did not show any notable activities. Further C-class activities are expected from 13691, with a chance of low M-class flares in the next 24 hours. The position of NOAA 13691 on May 26 at 11:30 UT is: N25E53 (-686", 412") 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#009 Default Target

25 May '24

Dear Collaborators, Solar activity was at a low level. The largest event during the period was a C5.8 flare at 17:16 UT on May 25 produced by yesterday's target NOAA 13679. This region has rotated beyond the west limb. Today the target will switch back to NOAA 13685 (S13W48) that has a beta-gamma/E-type configuration. If possible, please also include the nearby region 13686 (S08W40, beta/C-type) in the field of view. These two regions produced two low C-class flares in the past 24 hours. C-class activities are expected in the next 24 hours. The position of NOAA 13685 on May 25 at 19:30 UT is: S13W48 (687", -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.

MM#009 Default Target

Dear Collaborators, Solar activity was at a moderate level. The target region NOAA 13679 produced two ~M1 flares (an M1.1 at 07:51 UT and an M1.4 at 20:05 on May 24) and seven C-class flares (including two C9). This region almost rotates over the west limb with some overlying loops visible above the limb. We will watch this region for a final 24 hours. Please note that NOAA 13685 (S13W34, beta-gamma/E-type) also produced two ~M1 flares (M1.5 and M1.3). Additional low M-class flares are probable from these two regions. The position of NOAA 13679 on May 24 at 19:30 UT is: S09W85 (932", -145") 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. The largest event in the past 24 hours was an M2.5 at 12:48 UT yesterday produced by the target region NOAA 13679. 13679 also produced two M1.0 flares plus more than ten C-class flares. This region retains a beta-gamma-delta/E-type configuration. C-class activities are expected with some chance of low M-class flares in the next 24 hours. The position of NOAA 13679 on May 24 at 03:30 UT is: S09W75 (904", -141") 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 level. The target region NOAA 13679 produced three M-class flares with the largest one being an M4.2 at 02:05 UT today. This region also produced six C-class flares including a C8.5. It has been designated as a beta-gamma-delta/E-type configuration. Additional low M-class flares are possible as this region further rotates to the west limb. The position of NOAA 13679 on May 23 at 03:30 UT is: S09W61 (820", -134") 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.
