MM#009 Default Target

31 Oct '22

Dear Collaborators, Solar activity continues at a very low level. The target region NOAA 13135 was the source of two C1 flares in the past 24 hours, including the largest one of a C1.4 at 10/31/02:20 UT. 13135 has been classified as a beta/E-type configuration with increasing in the sunspot area and number of spots. More B- class and low C-class flares are expected in the next 24 hours. The position of NOAA 13135 on October 31 at 16:30 UT is: N27E30 (-431", 380") 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 to be at a very low level. The largest event since the last message was a C1.3 flare produced by yesterday's target region NOAA 13130 at 10/30/14:48 UT. 13130 almost rotated beyond the west limb. Today the target will switch to NOAA 13135 that has a beta/D-type sunspot group. 13135 produced a few ~C1 flares in the recent two days, but it appears to decay now, showing mixed polarities in its intermediate portion. Further low B- and C-class activities are expected in the next 24 hours. The position of NOAA 13135 on October 30 at 16:30 UT is: N27E43 (-588", 388") 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 largest event since the last message was a C1.9 flare produced by target region NOAA 13130 at 10/29/09:49 UT. Please note that there were another four ~C1 flares produced by a newly emerged region NOAA 13135 (N27E56, classified as a beta/B-type configuration). Target region 13130 remains its beta/D-type configuration but seems to show signs of decay. We will watch this region for a further 24 hours when it is rotating over the west limb. Low C-class activities are expected in the next 24 hours. The position of NOAA 13130 on October 29 at 15:30 UT is: S25W67 (806", -434") 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, Target region NOAA 13130 was the source of two ~C1 flares (C1.2 and C1.0) and two B9 flares since the message. The largest event of the period was a C1.3 flare at 10/27/09:30 UT produced by NOAA 13131 (N23E21, beta/C-type). NOAA 13130 still has a beta/D-type sunspot group and shows mixed polarities in its intermediate portion. Further C-class activities are expected in the next 24 hours. The position of NOAA 13130 on October 28 at 13:19 UT is: S25W52 (690", -452") 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, Yesterday's target region NOAA 13126 was flare quiet and almost rotated over the west limb. NOAA 13130 and 13133 were the sources of a few C-class flares in the past 24 hours, including the largest one of a C9.0 at 10/27/06:39 UT from 13130 (this needs to be confirmed later). 13130 (S24W34) and 13133 (N26E56) were classified as beta/D-type and beta/C-type configurations, respectively, and both are showing new magnetic flux emergence. Today we will watch NOAA 13130, which seems to develop more rapidly. Additional high C-class flares are expected in the next 24 hours. The position of NOAA 13130 on October 27 at 07:30 UT is: S24W34 (494", -454") 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 largest event since the last message was a C4.9 flare at 10/25/18:52 UT produced by a newly numbered region NOAA 13133 that has a beta/C-type configuration. 13133 also produced a C3.3 flare at 10/25/15:04 UT. The Target region NOAA 13126 remains its beta/D-type sunspot group and only produced three ~B7 flares of the period. We will watch this region for a further 24 hours until it rotates over the west limb. Additional C-class flares are probable in the next 24-hour period. The approximate position of NOAA 13126 on October 26 at 08:00 UT is: S08W89 (900", -190") 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 13126 was the source of a C2.5 flare at 10/24/13:30 UT (the largest one of the period) and also several high B-class flares. 13126 has been classified as a beta/D-type region with increasing the sunspot area and number of spots. This region seems to continue emerging new magnetic fluxes though with a much lower rate. A newly emerged region numbered as NOAA 13131 (N23E68, alpha/H-type) also produced a few B-class flares. B-class activities are expected with a good chance of C-class flares in the next 24 hours. The position of NOAA 13126 on October 25 at 03:30 UT is: S10W53 (760", -217") 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 slightly since the last message. The target region NOAA 13126 has been emerging new magnetic flux in its trailing portion and produced the largest event of the period, a C4.2 at 10/24/07:50 UT, although it retained a beta/C-type classification. Please note that a new region (numbered as NOAA 13130 with a beta/C-type configuration) emerged yesterday and was the source of a few B- and low C-class flares. Additional C-class activities are expected in the next 24 hours. The position of NOAA 13126 on October 24 at 07:30 UT is: S10W42 (637", -230") 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 X-ray flux has dropped to the mid-B-level since the last message with NOAA 13122 now fully behind the northwest limb. NOAA 13126 has remained quiescent and continues to decay. It shall continue as the target region for a further 24 hours although no significant chance in activity is expected at this time. The position of NOAA 13126 on 23-Oct-2022 at 11:30 UT is: S11W32, ( 503", -256" ) 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 the mid-C-level since the last message due to another resurgence from NOAA 13122 which is now beyond the northwest limb. NOAA 13125, an alpha region, also produced a C4.1 flare at 02:44 UT today. NOAA 13126 has remained quiescent and appears to be in decay. It shall remain the target region for a further 24 hours with isolated low-level events possible. The position of NOAA 13126 on 22-Oct-2022 at 11:30 UT is: S11W18, ( 293", -267" ) 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.
