Returning home from a snowshoe hike with a friend, I spotted a sun dog. We were near his house in Lebanon, but we stopped briefly so I could get the photo below.
At my friend’s home I took more photos of the sun dog, then I looked to see if there might also be iridescent clouds present. Sure enough there were, just above the sun. We had to block the sun with our hands in order to clearly see them.
Here are a few of the photos I took over the next 10 minutes. In one of them you can see an airplane and its contrail in the bottom right corner.
Before I left I took one more photo of the sun dog.
After I arrived home I took another photo of the iridescent clouds.
