Photo date: August 1, 2016. Photographer: Mark Mahin.
The photo below shows (at its top) a moving orb I photographed in Grand Central Terminal in New York.
Below is a closeup. We see an orb that seems to be speeding in a snake-like motion. I have 25 times previously photographed orbs moving in this kind of undulating, snake-like motion. You can see the examples here.
