MM#009 Default Target

30 Sep '19

MM#009 Default Target Dear Collaborators, The southwestern limb target filament/prominence system has occasionally shown an active phase during the past 24 hours but the default target will switch to a tiny region that is rotating over the southeastern limb at S09 degrees. The region is currently displaying an A-type/alpha sunspot group.The region was the source of some minor bright surges today. No noteworthy solar flare activity expected. The position of the target on September 30 at 18:00 UT is: S09E85 (Solar X = -943", Solar Y = -159") 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 an extremely low level with the GOES soft X-ray flux flat at ~A7. Yesterday's bright point target has faded away. Today the target will switch to a small prominence on the southwest limb. No note- worthy activities are expected in the next 24-hour period. The approximate position of the target on September 29 at 19:30 UT is: S45W89 (600", -700" ) 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, without any flares occurring in the past 24 hours. The bright "point" (or compact loops) target is rotating onto the visible solar disk. It continuous showing small EUV jets. No noteworthy activities are likely in the following 24-hour period. The approximate position of the target on September 28 at 13:30 UT is: S13E72 (-900", -240" ) 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, without any spots or flares in the past 24 hours. Yesterday's target, a bright jet structure in the north polar coronal hole, has faded away. Today we will watch a limb region where shows some overlying loops or jet structures. No noteworthy activities are expected in the next 24 hours. The approximate position of the target on September 27 at 07:30 UT is: S11E90 (-950", -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, Solar activity continues at an extremely low level with the GOES soft X-ray flux flat at ~A4. Yesterday's bright point target has faded away. Today we may switch to a bright jet structure in the north polar coronal hole, which has lasted for one day. Quiet-Sun conditions continue in the next 24 hour period. The approximate position of the target on September 26 at 07:30 UT is: N74E60 (-180", 900" ) 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 background level, without any spots, flares. Yesterday's bright point target has decayed. Today we will switch to another EUV bright point in the southeast quadrant (if you would like). Quiet-Sun conditions should continue in the next 24 hours. The approximate position of the target on September 25 at 13:30 UT is: S28E29 (-420", -500" ) 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 an extremely low level with the visible solar disk remaining spotless. There show up some EUV bright points in the EUV passbands. Today we will watch one of them near an equatorial coronal hole. Quiet-Sun conditions continue in the following 24 hours. The approximate position of the target on September 24 at 07:30 UT is: N10W09 (100", 70" ) 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 an extremely low level. The visible solar disk remains spotless. Only some EUV bright points appear on the Sun. Today there will be no default target. Quiet conditions continue in the next 24 hours.

Dear Collaborators, Solar activity remains unchanged. The small ERF in the southwest quadrant has already decayed. The compact loop system visible in EUV images shall remain the target region for a further 24 hours. No increase in activity expected. The approximate position of the target region on 22-Sep-2019 at 12:40 UT is: S12W22, ( 348", -305" ) 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 background levels. A small, bipolar emerging flux region is now visible in the southeast quadrant and shall be the target region for the next 24 hours. No significant change in activity expected at this time. The approximate position of target region on 21-Sep-2019 at 13:30 UT is: S14E10, ( -161", -343" ) 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.
