2017 September 11 Sun - AR12673 finale with a spectacular arch prominence show
The title of my post yesterday is a bit premature, as AR12673 started to produce a huge arch prominence around September 10, 17 UTC, and this arch show continues well into September 11, 07 UTC.
The arch prominence show much plasma dynamics, and the bright knots are literally observed to move along the magnetic lines.
The arch prominence show up well even in the whole-disc images.
Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm (f/28) for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
