There was a recent significant flare from behind the SE limb of the Sun - I am lead to believe when these occur close to the limb there is often a loop prominence held in place by the magnetism and gravity - stuff spewing out / and looping back.
I believe I caught this post flare loop prom from my session today - it is feint in my image (set up) but there appears to be a looping structure at the correct location (8 o'clock in the image).
I tried to do some higher magnification imaging but was unsuccessful - the structure had changed.
Image with LS60 and DMK51 - the second image is just of the disc surface.
