Jenny Legacy of Halifax, Nova Scotia sent us this ghost picture and story. Looks like an orb moving at a high rate of speed, trying to get around the corner; or did a hair get in front of the lens?
"Doing my rounds of the building I'm working in (around 1AM) and felt that something was behind me, so I took the picture without turning around. This is what I got. I took a couple later of the same spot, and nothing showed up."
