MM#009 Default Target
by Max Millennium Chief Observer 28 Feb '21

28 Feb '21

Dear Collaborators, The level of solar activity is low. The target region NOAA 12804 has rotated up to the North West limb, and at the start of the UT-day it had remained classed as a beta/D-type sunspot group. This region was once again the source of B-class activity since the last message, as well as the largest flare - a C3.9 on 28-Feb-2021 at 06:40 UT. NOAA 12804 will remain the target for the next 24 hours while it rotates fully over the North West limb. Further B-class activity is expected in the following 24 hours, with a good chance of another mid-C-class flare. The position of NOAA 12804 on 28-Feb-2021 at 20:00 UT is: N21W85 , ( 900", 354" ) 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 at a low level. The target region NOAA 12804 did not evolve significantly in the past 24 hours, and remains classified as a beta/D-type sunspot group. NOAA 12804 has once again produced multiple B-class flares over the last 24 hours as well as the largest flare - a C2.7 that occurred on 27-Feb-2021 at 17:51 UT. More B-class flares are expected in the next 24-hour period, with a chance for another C-class flare. The position of NOAA region 12804 on 27-Feb-2021 at 23:30 UT is: N18W71 , ( 871", 335" ) 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. Over the past 24 hours the target region NOAA 12804 initially grew in spot area before starting to decay, and remains classified as a beta/D-type sunspot group. The smaller region NOAA 12805 produced the largest flare of the period (a B9.5 on 26-Feb-2021 at 07:02 UT) that was accompanied by a weak eruption. However, NOAA 12805 has now decayed to plage so NOAA 12804 remains the target. Throughout the period 12804 has again produced multiple B-class flares. More B-class activity is expected over the following 24 hours. The position of NOAA region 12804 on 26-Feb-2021 at 23:00 UT is: N19W59 , ( 790", 357" ) 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 at a very low level. Target region NOAA 12804 has grown over the past 24 hours to now be classified as a beta/D-type sunspot group. 12804 has continued to produce multiple low B-class flares, with the largest being a B4.6 on 25-Feb-2021 at 06:28 UT. Further B-class activity is expected over the next 24-hour period. The position of NOAA region 12804 on 25-Feb-2021 at 23:30 UT is: N19W46 , ( 659", 394" ) 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 12804 has grown slightly in spot area over the past 24 hours while NOAA 12805 has decayed significantly. NOAA 12804 remains classified as a beta/C-type sunspot group and continues to produce low B-class flares, the largest being a B2.6 on 24-Feb-2021 at 11:03 UT. More B-class activity is expected in the following 24 hours. The position of NOAA region 12804 on 24-Feb-2021 at 22:00 UT is: N19W32 , ( 487", 411" ) 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 at a very low level. The target spot region has been confirmed as being numbered NOAA 12804, with the slightly smaller spot region in the southern hemisphere numbered NOAA 12805. Both of these regions are classed as beta/C-type sunspot groups. NOAA 12804 stays as the target region by continuing to produce multiple low B-class flares (the largest being a B3.3 on 23-Feb-2021 at 00:11 UT). Further B-class activity is expected over the next 24-hour period. The position of NOAA region 12804 on 23-Feb-2021 at 18:00 UT is: N18W18 , ( 287", 407" ) 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. The previous target region has decayed to plage since the last message, while two new spot regions are in the process of emerging close to the central meridian. Of these, the spot group in the northern hemisphere will become the new target region following it producing two B-class flares - the largest being a B5.4 on 22-Feb-2021 at 21:19 UT. This region is expected to be numbered as NOAA 12804 at the start of the next UT day and it has still only developed a rudimentary penumbra around its leading polarity spot (so potentially a beta/C-type sunspot group classification). Further B-class activity is expected in the following 24 hours. The approximate position of this region on 22-Feb-2021 at 22:30 UT is: N20W03 , ( 47", 443" ) 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 very low levels. The alpha region NOAA 12803 in the northeast quadrant has produced only A-level activity since the last message, and appears to be in decay. Its negative polarity sunspot appears to be embedded in the trailing positive polarity plage. It shall continue to be the target region for the next 24 hours with only low-level flares expected. The position of NOAA 12803 on 21-Feb-2021 at 12:30 UT is: N21E42, ( -607", 428" ) 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 low levels. The active region in the northeast quadrant has now been designated as NOAA 12803 and is classified as an alpha/A-type region. It has produced several A-class flares since the last message as well as a B1.1 flare at 11:47 UT today, It shall remain the target region with further low-level activity expected over the next 24 hours. The position of NOAA 12803 on 20-Feb-2021 at 12:30 UT is: N21E55, ( -743", 409" ) 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 near the northeast limb has now rotated on to the visible solar disk. It remains unnumbered and unclassified, but does appear to possess some small sunspots. The region has continued to produce A- and B-level activity since the last message, including a long-duration B1.4 flare at 20:00 UT yesterday. Further B-level activity expected over the next 24 hours. The approximate position of the target region on 19-Feb-2021 at 12:30 UT is: N23E72, ( -851", 410" ) 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.
