Hundreds of witnesses have filed reports with the American Meteor Society about a large, bright, long-lasting fireball over the U.S. East Sunday evening.


The American Meteor Society (AMS) says that hundreds of witnesses have filed reports of a large, bright, long-lasting fireball seen over the U.S. East (New England) on Sunday evening, January 12, 2014. The time was 5:20 p.m. EST (2220 UTC). According to the AMS:

Witnesses reported the brightness greater than the full moon.

The fireball was seen from primarily Connecticut, but witnesses from Massachusetts, Maine, New Hampshire, New Jersey, Pennsylvania and Rhode Island also reported seeing the fireball.

From any one spot on Earth, it’s rare to see a meteor as bright as the moon. But meteors of this brightness are not uncommon, given the Earth as a whole. They result from chunks of space debris entering our atmosphere. In recent years, due to increasing interconnectivity between people, we hear about these meteors more often!

Bottom line: The U.S. East was treated to a large, bright fireball – as bright as the moon, according to reports – on Sunday evening, January 12, 2014.
