Astronomer Derrick Pitts of the Franklin Institute in Philadelphia told our sister station WPVI-TV that the light was from a SpaceX launch.
The National Weather Service also said the light is "most likely" from the rocket.
According to SpaceX, there was a launch at 6:01 a.m. at Kennedy Space Center in Florida.
