Visibility IV / V

I already meant to throw the pictures of the GoPro timelie experiment in the trash when there were no halos, But Mauri Korpi had put the canola in Bishop's ring, so I have to put it with me. Nice to always learn something new.

      Anomaalisella kehällä tarkoitetaan kehää, jonka ulkonäkö ja syntytapa on ilmeisen poikkeava. Kyseeseen tulevat varsinkin ilmakehän epäpuhtauksiin syntyneet hehkut Auringon ympärillä.
