MM#009 Default Target

Dear Collaborators, Solar activity continues at a very low level with the soft X-ray flux around ~C1 level. The target region NOAA 13098 was the source of a C1.1 at 09/09/21:02 UT. NOAA 13097 (S11W27) also produced a C1.1 flare at 09/09/15:30 UT. A newly emerged region near the south-east limb (S23E66) was the source of a C1.0 flare plus three high B-class flares. The target NOAA 13098 has been designated as a beta/C-type sunspot group today. It is showing mixed polarities in its leading portion. B- and C-class activities are expected in the following 24 hours. The position of NOAA 13098 on September 10 at 03:30 UT is: N17E03 (-47", 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 continues at a very low level. The largest event in the past 24 hours was a C2.1 flare at 09/08/16:57 UT produced by a newly emerged region numbered as NOAA 13098. 13098 also produced four ~C1 flares. Today we will watch this region. It was designated as a beta/B-type region but continues to show flux emergence. If possible, please also include NOAA 13094 (N17W03) in the field of view, which produced a C1.2 flare. Yesterday's target NOAA 13096 was the source of two low C-class flares during the period. Further C-class activities are expected from various regions in the next 24 hours. The position of NOAA 13098 on September 9 at 07:30 UT is: N15E13 (-207", 131") 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 with the soft X-ray flux flat at ~C1 in general. The target region NOAA 13096 was the source of four C1 flares. 13096 has been classified as a beta/ D-type region today. New spots continue to emerge from this region. Additional C-class activities are expected in the next 24 hours. The position of NOAA13096 on September 8 at 07:30 UT is: N18E53 (-724", 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 been at a very low level since the last message. Yesterday's target region NOAA 13089 was the source of seven low C-class flares during the period, the largest one being a C3.2 at 09/06/18:21 UT. 13089 has now completed its west limb passage. Today the target will switch to NOAA 13096 which is increasing in its sunspot area and number of spots. C-class activities are expected in the next 24 hours. The position of NOAA13096 on September 7 at 15:30 UT is: N18E62 (-800", 238") 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 target region NOAA 13089 was the source of more than 10 C-class flares as well as an M1.0 flare (at 09/05/17:58 UT) since the last message. 13089 was designated as a beta-gamma/ E-type configuration. It is almost rotating beyond the west limb. We will watch this region for a further 24 hours. Limb or occulted C-class flares are expected with some chance of a low M-class flare in the next 24 hours. The position of NOAA13089 on September 6 at 03:30 UT is: S23W90 (875", -368") 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 target region NOAA 13089 was the source of numerous C-class flares in the past 24 hours, the largest one being a C8.2 at 09/04/16:30 UT. 13089 retains its beta-gamma-delta/E-type configuration and is rotating over the west limb. Further C-class activities are expected, still with a chance of a low M-class flare in the next 24 hours. The position of NOAA13089 on September 5 at 07:30 UT is: S23W78 (856", -391") 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, NOAA 13089 has continued to produce C-level activity since the last message, the largest event being a C6.4 at 02:51 UT today. The target region has once again grown in size and complexity as it approaches the western limb, and has regained its beta-gamma-delta configuration. Further C-class events likely over the next 24 hours with chance for an M-class flare before west limb passage. The position of NOAA 13089 on 4-Sep-2022 at 07:30 UT is: S22W65, ( 800", -400" ) 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, NOAA 13089 has continued to produce C-level activity since the last message, the largest of which was a C3.8 flare at 17:04 UT yesterday. The region is currently classified as a beta-gamma/E-type region with a sunspot area of 350uh. Further C-level activity likely as the region approaches the southwest limb. The position of NOAA 13089 on 3-Sep-2022 at 11:30 UT is: S23W53, ( 700", -435" ) 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 continued at the low C-level. NOAA 13089 remains largely unchanged in terms of size and complexity, and has produced several C1 flares since the last message. The new active region on the eastern limb has been designated as NOAA 13092 and also produced some ~C1 flares. NOAA 13089 shall continue as the target region with further C-level activity likely. The position of NOAA 13089 on 2-Sep-2022 at 11:30 UT is: S22W40, ( 568", -439" ) 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 from NOAA 13089 has remained steady at the C1 level since the last message, although a new unnumbered region rotating onto the eastern limb was the source of a C4 flare at 13:46 UT today. NOAA 13089 has reestablished its beta-gamma-delta configuration due to polarity mixing in its trailing spot and has begun to increase in size once again. It shall continue as the target region with further C-level activity likely over the next 24 hours. The position of NOAA 13089 on 1-Sep-2022 at 11:30 UT is: S22W27, ( 401", -453" ) 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.
