MM#009 Default Target
by Max Millennium Chief Observer 31 Mar '19

31 Mar '19

Dear Collaborators, Solar X-ray flux remains at background levels. A new bipolar active region has emerged in the northeast quadrant over the last few hours but is not yet numbered. This shall be the new target region, with a slight chance for some low-level activity over the next 24 hours if the region continues to develop. The approximate position of the target region on 31-Mar-2019 at 17:00 UT is: N12E48, ( -695", 272" ) 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 visible solar disk is now featureless, with the northern hemisphere filament having decayed since the last message. There is no target region available today.

Dear Collaborators, Solar activity remains at background levels. The only viable target on the visible solar disk continues to be the high latitude filament, which is showing signs of decay. No activity expected over the next 24 hours. The approximate position of the target region on 29-Mar-2019 at 14:33 UT is: N35W09, ( 118", 640" ) 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 visible solar disk remains spotless with no change in activity since the last message. The target shall continue to be the small filament crossing the northern central meridian. No activity expected over the next 24 hours. The approximate position of the target region on 28-Mar-2019 at 14:30 UT is: N45E02, ( -18", 757" ) 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 visible solar disk is now spotless and solar X-ray has returned to background levels as both NOAA 12735 and 12736 have rotated behind the western limb. The new target region shall be the filament in the northeast quadrant visible in H-alpha images. No significant increase in activity expected over the next 24 hours. The approximate position of the target region on 27-Mar-2019 at 08:30 UT is: N55E19, ( -179", 845" ) 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 returned to background levels with NOAA 12736 now beyond the western limb. NOAA 12735, also now on the western limb, has produced some low B-level events since the last message and shall be the new target region. No significant change in activity expected before the region also rotates behind the solar disk. The position of NOAA 12735 on 26-Mar-2019 at 14:30 UT is: N02W91, ( 960", 31" ) 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 low levels. NOAA 12736 has continued to produce B-level activity over the past 24 hours, the largest being a B9.6 flare at 19:16 UT yesterday. The region is now on the western limb and shall remain the target region for an additional 24 hours. Further B-level activity likely with chance for an isolated C-class flare before west limb passage. The position of NOAA 12736 on 25-Mar-2019 at 14:30 UT is: N08W91, ( 952", 130" ) 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 low. NOAA 12736 has been reclassified as a beta/E-type sunspot group as it now rotates up to the North West limb, although this suffers from significant foreshortening effects. NOAA 12736 continued to produce multiple B-class events, the largest being a B9.9 flare on 23-Mar-2019 at 23:30 UT. More B-class activity is expected over the next 24-hour period. The position of NOAA 12736 on 24-Mar-2019 at 12:30 UT is: N08W84, ( 948", 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 is at a low level. NOAA region 12736 grew in spot area but decreased in magnetic complexity since the last message. This region is now classified as a beta-gamma/E-type sunspot group and continued to be the source of B-class and low C-class flares, the largest being C1.4 on 22-Mar-2019 at 20:16 UT. B-class flares are expected in the following 24 hours, with a chance for another low-to-mid C-class flare. The position of NOAA 12736 on 23-Mar-2019 at 11:00 UT is: N08W68, ( 886", 176" ) 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 low-to-moderate. NOAA 12736 grew in spot area since the last message and developed a more complex magnetic configuration in its trailing portion. 12736 is classed a beta-gamma-delta/D-type sunspot group and continues to produce C-class activity, the largest being a C4.8 flare on 21-Mar-2019 at 05:05 UT. Further C-class activity is expected over the next 24-hour period. The position of NOAA 12736 on 22-Mar-2019 at 11:00 UT is: N09W54, ( 772", 218" ) 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.
