The image was first used in connection with the Nimitz incident in this 2015 article:
It was used in the original "To The Stars" presentation by Chris Mellon
The image was also used today by George Knapp in a piece on LasVegasNow
However this "UFO" image is in fact of a mylar party balloon. It comes from this Rense.com page dated 2005:
UFO Photographs - Eccles, Manchester UK
By Steve Mera
At around 10.00am this morning July 10th 2005 I was sitting outside with 4 colleagues when I saw a very bright flashing rotating object in the sky. This I pointed out to everyone, and everyone saw it. At this point I must say that I am one of the worlds greatest sceptics with regards to UFOs. I managed to photograph the object and have 6 very good photos of it.
This object, and the described motion, is a perfect match for a mylar party balloon in the shape of a "1", a common digit in party celebrations.
