Day 12.041: Halo

One thing southern Maine seems to do very well is generate halos. I didn't know what a sun dog or a circular halo was before we moved here but they are a not uncommon sight in the winter here - formed by ice crystals in the atmosphere on a sunny day.

Today, there was a very clear 22° halo and a very bright upper tangent arc (I looked that up today).

I know this looks like lens flare, but the only actual lens artifact is the green spot just above the sun - the radial pattern and the strange shaped light spot above it were very real.
