A Speeding Orange Orb

Photo date: December 3, 2014.  Photographer: Mark Mahin.

In this indoor photo of a wall, we see what photographers call a "ghosting" effect that is a sign of rapid movement, movement faster than the camera's shutter speed.  Because this shot was made with a Sony camera with a shutter speed of 1/1600 of a second, the orb must have been moving very fast.

Dust level: 175/2 (Fair). No reflective surfaces nearby. No orbs were seen in photos taken soon before and after this photo, which argues against the possibility of dust. No flying insects observed at photo site.
