The "Ghost" Bent Right, and Then Bent Left

Photo date: January 25, 2016. Photographer: Mark Mahin.

The photos show strange transformations of the light coming from a building in New York City. Here is the first photo, which showed nothing unusual.

But the next photo showed the light from the sign rising up.

The next photo showed this ghostly light rising even higher.

When I moved a little to the right, I got the same "rising ghost" effect, but this time the "ghost" was  tilting to the left.

The camera was held stable while all of these photos were taken.The photos were flash photos with an exposure time of 1/30 of a second, using normal camera settings (no "Night picture" setting).
