Dog days of Winter

A chilly -18 F this morning.  My wife left the house first this morning and soon phoned back, "Sun dogs!"  So I hurried the kids into the car and headed to daycare with a few stops along the way for pics.  Because the sun is continually rising and changing its angle with the atmosphere, and the atmosphere is continually changing with wind and clouds, the presentation of this atmospheric phenomena continually changes.  Sometimes it lasts but moments.  Today it presented for a long time, culminating with a halo.

Atmospheric Effects

There was a nice solar pillar at sunrise this morning but I had trouble getting a clear shot due to all the trees.  There was another one at sunset that was bright red but by the time I got to a clearing it was gone.  This evening there was a lunar corona again.  There were lots of clouds passing in front of the moon so I took a 30s exposure to show the full ring.
