MM#009 Default Target

Dear Collaborators, Solar activity is at a very low level. Target NOAA 12924 displayed an increase in magnetic complexity since yesterday's message and was classified as a beta-gamma/E-type sunspot group. However, NOAA 12924 appears to have already decreased to a beta configuration. This region has remained flare quiet while a C1.0 flare occurred on 11-Jan-2022 at 08:18 UT from a location further East than NOAA 12927. The target instead changes to NOAA 12926 that began the UT day classified as a spotless H-alpha plage region. 12926 now has a small leading-polarity spot with a trailing-polarity pore and it appears to be undergoing emergence of an additional bipole to its North. A location close to NOAA 12926 was the source of 3 B-class flares since the last message, the largest being a B7.1 flare on 11-Jan-2022 at 09:14 UT. More B-class flares are expected in the following 24-hour period, with a chance for a low C-class flare if NOAA 12926 continues emerging more flux. The approximate position of NOAA 12926 on 11-Jan-2022 at 23:30 UT is: N17W36 , ( 550", 341" ) 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 very low. Target region NOAA 12924 has shown signs of slight decay with decreasing in sunspot area and number of sunspots, but has maintained its classification as a beta/E-type sunspot group. This region has produced two B-class flares since the last message, including the largest event of the period (a B5.5 flare on 9-Jan-2022 at 15:56 UT). Further B-class activity is expected over the next 24 hours, with a chance for a C-class flare. The position of NOAA 12924 on 10-Jan-2022 at 17:00 UT is: S31W23 , ( 327", -448" ) 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 reverted to B-level as NOAA 12924 crossed the central meridian. There has also been a B7.7 flare from a spotless region close to the northeast limb. NOAA 12924 retains its beta/E-type configuration and shall continue as the target region for a further 24 hours. Further B-level activity possible with chance for an isolated C-class flare. The position of NOAA 12924 on 9-Jan-2022 at 16:30 UT is: S31W10, ( 145", -445" ) 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 12924 has continued to develop since the last message and was the source of a C2.7 flare at 22:01 UT yesterday. The region now has a beta/E-type configuration with an area of almost 500 uh as it approaches the central meridian. It shall continue as the target region with further C-level activity expected over the next 24 hours. Possibility remains for a low M-class flare. The position of NOAA 12924 on 8-Jan-2022 at 08:30 UT is: S31E01, ( -14", -447" ) 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 in the southeast quadrant, NOAA 12924, has continued to develop over the past 24 hours and was the source of two C1.1 flares since the last message. The region is currently classified as a beta/D-type region, but shows strong mixed polarities within its trailing spot. Good chance of increased activity over the coming days with possibility of a low M-class flare. The position of NOAA 12924 on 7-Jan-2022 at 12:30 UT is: S31E13, ( -188", -449" ) 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 region close to the southeast limb has now been designated as NOAA 12925 but has remained quiescent since the last message. Neighboring NOAA 12924 has undergone significant flux emergence in its trailing portion over the past 24 hours producing a series of B-class flares and shall be the new target region. Further B-level activity expected as well as chance of a C-class flare if the region continues to develop. The position of NOAA 12924 on 6-Jan-2022 at 12:30 UT is: S31E27, ( -380", -455" ) 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 remained at low levels. The new target region on the southeast limb remains unnumbered but has produced several more low B-class flares since the last message, along with nearby NOAA 12924. The target region appears to be a compact beta region surrounded by decaying plage. Further low level activity possible over the next 24 hours. Also include NOAA 12924 in your field of view if possible. The approximate position of the target region on 5-Jan-2022 at 12:30 UT is: S31E84, ( -832", -496" ) 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 at the B-level with several events emanating from a region beyond the southeast limb. The largest of these was a B6.3 flare at 23:10 UT yesterday. With NOAA 12918 now beyond the western limb, this approaching region shall be the new target region. Its magnetic configuration is uncertain at this time, but further B-level activity is likely as it rotates into view with chance of a C-class flare. The approximate position of the target region on 4-Jan-2022 at 12:30 UT is: S31E86, ( -834", -498" ) 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 is currently at B-level with occulted flares still being produced by NOAA 12918, which is now behind the northwest limb. The rest of the visible solar disk remains quiescent and so the looptops of NOAA 12918 shall remain the target region for a further 24 hours. Isolated, occulted low-level events possible. The approximate position of NOAA 12918 on 3-Jan-2022 at 12:30 UT is: N22W91, (903", 363") 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, Target region NOAA 2918 was the source of two limb occulted C-class events since the last message. The largest was a C2.3 at 01/01/19:09. 2916 also produced a few limb occulted B-class events. A B5.5 event at 01/02/17:02 was associated with a bright flare spray. NOAA 2916 (S18W71, E-type/beta) continues to slowly decay and was again quiescent. Limb occulted B-class events possible with a slight chance of a C-class event in the next 24 hours. The position of NOAA 2918 on January 02 at 16:30 UT is: N22W91 (Solar X = 903", Solar Y =363") 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.
