Another Speeding Air Orb

Photo date: November 23, 2014.  Photographer: Mark Mahin.

In this indoor picture we see a fast-moving white orb. Here is a larger version of the photo:



Here is a closeup of the orb, with "Auto-adjust colors" used from the menu of the IrvanView program:


The photo shows what photographers call a "ghosting" effect, which is a sign of rapid movement. Given the  camera's shutter speed of  1/2000 of a second, an effect like this can only be produced by an object moving very quickly, much faster than a speck of dust drifts around in the air.

Dust level: 335/9 (Fair). No artificial light was involved in the photo area except the camera flash. There was no possibility of a hair in front of the camera lens, because the photo was made by someone with very short hair.   No orbs shown in photos taken at same place shortly before and shortly after this photo, which argues against an explanation of dust. No insects observed at the photo site in the previous 5 days.
