ice halos and other optics

Diamond dust parhelia on 29 November 2010 from Kontiolahti snowguns

I screwed up this one. The condidionts were on and I was waiting in Mustavaara for three hours for them to start the snowguns while there was actually diamond dust from Kontiolahti biathlon stadium snow gunning not far from Mustavaara. Eventuallly I saw the Kontiolahti swarm in the distance as I walked up the Mustavaara flank. After three km of driving I entered the diamond dust and got a couple of photos from parhelia against pine forest. The ice fog extended at least 12 km from the source, but I was still deep within. Who knows how far it reached.
