Now that I've posted a sun halo, I guess I should show a sundog

picture from fall 2011
This picture is of a sundog, related to the halo. Often they come in pairs; this one was single. Called sundogs because they follow the sun around. There can be one on each side of it, at 22 degrees.

Since I learned that they exist, I've been seeing them 3 or 4 times a year. Before that, I never saw them, even during the years I worked outdoors, until the end when I knew about them.

This is the best one I've seen.

Update: for best sky pics, especially without a polarizing filter, try lowering your exposure by a stop or even 2 stops. Or, of course, do that afterwards in Photoshop by adjusting the exposure setting.

Aligned hexagonal ice crystals in the upper atmosphere. This one shows the prism-effect of spectral colors too.
