Evening Colors
A rainstorm moving from west to east passed by on the evening of August 4th. Glancing out a window afterward I noticed a dark, stormy sky in the east and bright sunshine in the west. Conditions looked good for a rainbow. Sure enough, there it was! A faint secondary rainbow was also visible. The lower the Sun, the higher the rainbow arc. In the picture below you can see evidence of the Sun's low altitude in the form of a tree shadow on the house.
The next picture shows the whole arc in a slightly distorted panorama. Notice the usual brightening within the primary rainbow's arc.
It's nice to see a rainbow every once in a while!
