A rare daytime fireball meteor exploded over the eastern United States on March 17th, creating a powerful sonic boom that was felt across multiple states and even captured by weather satellites in orbit. The event, caused by a 7-ton space rock roughly the size of a refrigerator, is unusual because most fireballs are seen at night; this one was visible even against a bright blue sky.
The Event: A High-Speed Atmospheric Entry
At approximately 8:57 a.m. EDT, the 6-foot-wide asteroid entered Earth’s atmosphere at roughly 40,000 mph (64,400 km/h) over Lake Erie in northern Ohio. Friction with the atmosphere rapidly heated the rock, causing it to burn and eventually break apart about 30 miles (48 kilometers) above Valley City, near Akron. The resulting flash lasted up to seven seconds.
Widespread Reports and Confirmation
The explosion was reported by over 200 eyewitnesses and captured on security cameras from as far away as Canada. Residents in Ohio, Pennsylvania, Delaware, Illinois, and several other states reported hearing a loud bang, later confirmed by the National Weather Service in Cleveland as a sonic boom. The event was so bright it was even detected by the NOAA GOES-19 weather satellite orbiting 22,000 miles above Earth.
Why This Matters: Rare Visibility and Potential Meteorites
Daytime fireballs are uncommon due to the overwhelming brightness of the sun. However, when they occur, they can briefly outshine the sun itself, creating spectacular light shows. The force of this particular fireball was equivalent to 250 tons of TNT, potentially shaking houses along its path.
Most meteor fragments burn up completely in the atmosphere. However, given the size of this space rock, experts believe meteorite fragments likely reached the ground. Simulations from the American Meteor Society (AMS) suggest they landed near Akron, Ohio.
“When an extraordinarily large meteor enters the atmosphere, it often survives down to the lower atmosphere where the air molecules are dense enough to carry sound,” says Robert Lunsford, a meteor observer with AMS. The sonic boom is a strong indication that fragments made it to the surface.
The rarity of daytime fireballs and the possibility of recovered meteorites make this event significant for scientific study and public interest. The fragments, if found, could provide valuable insights into the composition of asteroids and the early solar system.
