On July 3rd, immediately preceding an epic sunset over the harbor (click to view), this cloud and its accompanying rain shower made a brief appearance over Marblehead Neck. I had just gotten to Crocker Park when I saw this rainbow form. I had just enough time to grab the camera, throw on a polarizer (to bring out the light in the rainbow and more clearly show its colors) and grab this image. Less than a second later, the colors began to fade and the rainbow was gone.
