Just before 8 p.m. last night, people all over the East Coast reported seeing a meteor in the sky. And a woman in Maryland appeared to get footage of it on her security camera:

Kim Fox, from Thurmont, Md., sent the video to WUSA9, which has another video of the apparent meteor. The American Meteor Society says it received hundreds of reports of the meteor, and it thinks it was a fireball:

For those not familiar with meteors and fireballs, a fireball is a meteor that is larger than normal. Most meteors are only the size of small pebbles. A meteor the size of a softball can produce light equivalent to the full moon for a short instant. The reason for this is the extreme velocity at which these objects strike the atmosphere. Even the slowest meteors are still traveling at 10 miles per SECOND, which is much faster than a speeding bullet. Fireballs occur every day over all parts of the Earth. It is rare though for an individual to see more than one or two per lifetime as they also occur during the day, on a cloudy night, or over a remote area where no one sees it. Observing during one of the major annual meteor showers can increase your chance of seeing another one of these bright meteors.

Also, to reassure you: “Very few meteors actually reach the ground as 99.99% completely disintegrate while still 10-20 miles up in the atmosphere.” Well, last month a meteorite (or brand new American weapon) crashed in Russia.
