It is wonderful to run into a rainbow with camera in hand, even a faint one like this. This rainbow appeared at dusk, coincidentally at the same time as a partial solar eclipse at Gillson Park in Wilmette, Illinois on May 20, 2012. Nearly missed it as I was facing the sunset. Fortunately, my daughter pointed it out.
Here are a few other rainbow images from the past.
