Canditate for 3rd order bow (4.8.2018, Vesanto/Finland)

Here is my first attempt to capture... I took these images some time ago, now are finally processed. The lens I used was Tokina 12-24/f4 (Nikon D200), at 12mm focal length. Images are not cropped, sun is behind & in the middle of flagpole at bottom right corner. https://timokuhmonen.smugmug.com/Natu...

Re: Optical phenomena on ice (Taivaanvahti, 21.2.2018)

Not sure what you refer with artificial light...? There was also video taken by the observer (iPhone), not sure if it has built in polarisation filters. The same effect is visible, approx 5...8 sec from start of a video. https://drive.google.com/file/d/1QzJn8CENCtJ-gxX0oTvXF-_OhVNucpKV/view Comments...
