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 Spaceweather.com.
On Jan. 4, 2014, the network reported 35 fireballs.
(19 sporadics, 14 Quadrantids, 1 lambda Bootid, 1 December Leonis Minorid)
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]
Note from Slaade; I am not familiar with a lambda Bootid meteor and could find very little information regarding them, mostly just in the context of actual "peculiar" stars. Would appreciate anyone who can provide a link to help me better understand what they are and where they come from. Thanks!
