Circumscribed halo and pyramid halos in Sardinia

This display was captured by Jan Drahokoupil in Sardinia on 6. September. The 22° halo is surrounded by elliptical circumscribed halo. The small halo around the sun is 9° halo or 9° column arc (or both together). Simulations could give better clue. Later on the display changed and there were also 18° plate arcs.

More photos here.

  1. That's what I've been wondering as well. Should make simulations.

  2. Wow, nice and clear display!

  3. Yep, this one's a beauty. It would be great to see photos from the anthelic region also.
