Details:
I has the forecast for a highcloud cover for the day (last friday) so I decided, before going to work, to set up my camera on my roof window (horizontally set) to shoot from dawn till dusk, with 6D+fisheye lens.
At the middle of the afternoon, a certain cloud cross the field of view, bringing first infralateral arc, then, as long at it went from right to left, in front of the sun, other arcs appeared: parhelic circle and the famous (and rare!) Wegener arc, first at the right of the sun, then at the left, as long as the cloud crossed the field of view.
Here is a stack of different images, processed in color (with unsharp mask) or in black and white (blue minus red technique) to enhance the phenomenon visibility.
It was my 3rd Wegener arc on camera, in 15 years of regular capturing!
