Rare Atmospheric Optics over Raleigh

December 2nd, 2009

If you looked to the sky last night around Raleigh, the moon and atmospheric ice crystals put on a show. I’m no expert, but I think I’ve identified several rare phenomena that were visible.

In this first image, there appears to be Parry Arc, faint Parhelic circle, and 22º halo.

    My friends and I noticed this last night. I thought it was just that thing when rings around the moon mean it’s going to rain, but I guess it was more?
