The Federal Aviation Administration (FAA) and law enforcement officials received calls; the latter saying it may have been a balloon of sorts. Witnesses saw the UFO floating 5,000 feet above 23th St. and Eighth Ave. The FAA said that the UFO wasn't detected by radar and police said that they would have been notified of any balloon-related activity in the area.
Shortly after the sighting, messages showed up in Twitter linking to a month-old press release about a UFO-themed book that predicted a sighting would occur on October 13.
Below is a photograph of the UFO taken by Jason Diamond via Twitter and a video taken by "matt52883".
