The loud boom many southern Westchester residents heard Saturday morning might have been caused by a meteor traveling through the atmosphere.
Bill Thys of the Rockland Astronomy Club said there was a very good chance a meteor could have caused the sonic boom, lohud.com reported.
Several police departments received calls about the noise, but they were unable to locate the source. The National Weather Service said there were no weather conditions at the time to account for such a noise.
A sonic boom occurs when something moves faster than the speed of sound, which is 761 mpg. Meteors entering Earth's atmosphere typically move at over 1,000 mph, according to Thys.
