Littele green men? UFO’s? Nope. Sorry. Just NASA.

A series of spooky lights above parts of the northeastern United States Saturday sparked a flurry of phone calls to authorities and television news stations.

NASA said strange lights seen in the Northeast on Saturday were caused by an experimental rocket.

CNN affiliate stations from New Jersey to Massachusetts heard from dozens of callers who reported that the lights appeared as a cone shape shining down from the sky. However, the lights were the result of an experimental rocket launch by NASA from the agency’s Wallops Flight Facility in Virginia, a spokesman told CNN.

Keith Koehler said the Black Brant XII Suborbital Sounding Rocket was launched to study the Earth’s highest clouds. The light came from an artificial noctilucent cloud formed by the exhaust particles of the rocket’s fourth stage about 173 miles high.
