Speeding Orb or Orb Foursome?

Photo date: January 2, 2015.  Photographer: Mark Mahin.

Below is a photograph taken in Grand Central Station in New York.

Below is a photo cropped from the top left corner of this photo. We seem to see what could be a foursome of orbs -- but perhaps the camera captured different position states of a single orb moving very rapidly in an undulating manner.  I have several photos of orbs moving in such a manner, as you can see by looking at my posts labeled "air orb undulation."
