Sometimes Dim, Sometimes Dazzling

Photo date: June 30, 2016. Photographer: Mark Mahin.

The orbs I photograph  in Grand Central Terminal in New York vary in color and brightness. Sometimes they look rather dim and colorless, as in the photo on the left. But many other times they look much more bright and more colorful, as in the case of the vivid blue orb shown on the right, which has a strange hole-like feature in its center.
