A Bright Meteor Streaked Across the Vermont Sky, Shaking Buildings in Its Path

“As the object (which was likely a fragment of an asteroid) penetrated deeper into the atmosphere, pressure built up on its front while a partial vacuum formed behind it. About 30 miles up, the pressure difference between front and back exceeded its structural strength. The space rock fragmented violently, producing a pressure wave that rattled buildings and generated the sound heard by those near the trajectory. Such a pressure wave can also couple into the ground, causing minor “tremors” that can be picked up by seismic instruments in the area,” NASA Meteor Watch explained on Facebook.

The fireball was captured by a camera at the Burlington International Airport. You can see the meteor streaking across the sky in the upper left.

Based on the infrasound measurements, the agency was able to determine that the meteor weighed about 10 pounds and had a diameter of six inches.
