Photo date: June 27, 2016. Photographer: Mark Mahin.
The photo below shows a blue orb speeding very fast at Grand Central Terminal in New York. The object appeared on the right edge of the photo. I always keep my camera strap (which is gray, not blue) wrapped around my wrist when photographing, so I know this was not my camera strap. You can actually see what looks like two position states of a single blue ball. This is one of very many blue speeding orbs I have photographed at this location, as you can see by looking at this set of photos.
