  • Mary, I am thrilled that you captured these images. It’s not every day we get to see these optical phenomena! You captured the circumzenithal arc (always my favorite), as well as the parhelic circle and the upper tangent arc! Even the rare Parry arc and supralateral arc! What an astonishing display. For more info, see http://www.atoptics.co.uk/halosim.htm

    • Jane, Thank you so much for the wonderful infromation and links. This is not an area of knowledge for me, and am fascinated by what I am learning.

  • Yeah! It’s really just sooooo cool! I got hooked on learning about haloes and such “back in the day.” Any time you see a sundog, look for the circumzenithal arc :-) It’s often there but no one ever looks straight up :-) Fun stuff! Enjoy!
