Here is the information from the Associated Press:
NASA says it successfully launched a rocket in Virginia as part of an experiment, and the blast may have caused dozens of people to report seeing strange lights in the sky.
The space agency said it launched the Black Brant XII on Saturday evening to gather data on the highest clouds in the Earth's atmosphere. About the time of the launch, dozens of people in the Northeast started calling local television stations to report seeing strange lights.
The calls came from as far away as Boston, which is about 380 miles northeast of the launch site.
The rocket is designed to create an artificial cloud. NASA hopes the experiment will provide information on the formation and properties of noctilucent clouds, which occur at high altitudes.
Several Action News viewers called our station all reporting the same thing.
They saw a strange, bright, cone-shaped light in the sky at about 7:55 p.m.
According to viewers, the light lasted only about 10 seconds.
An explanation has been discovered.
NASA launched a weather research rocket from its Wallops Flight Facility in Virginia, at about 7:46 tonight.
It is a four-stage rocket and the light seen up and down the East Coast is probably related to the burning of fuel during one of those stages about ten minutes after launch.

A user on flickr seems to have taken a picture of the light, as seen above. Is that what you saw?
