Hey I captured this yesterday driving back from Burlington, Ontario to Hamilton, Ontario.
Source and special thanks: UFOs NorthWest
Note from The Black Vault: I am always very cautious with photos like this. A bright light source, especially the sun, tends to cause lens flare. I believe strong evidence to support this is the "UFO" is a nearly identical color to the light source behind it, and think this can be explained as probable lens flare.
