NASA all-sky cameras reported 54 fireballs December 12, 2013


All Sky Fireball Network

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on

On Dec. 12, 2013, the network reported 54 fireballs.
(26 sporadics, 23 Geminids, 3 December Monocerotids, 1 alpha Canis Majorid, 1 sigma Hydrid)

In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]
