Asteroid 2011 CQ1 was discovered by the Catalina Sky Survey on February 4 and made a record close Earth approach 14 hours later on February 4 at 19:39 UT (14:39 EST). It passed to within 0.85 Earth radii (5480 km) of the Earth's surface over a region in the mid-Pacific. This object, only about one meter in diameter, is the closest non-impacting object in our asteroid catalog to date. Prior to the Earth close approach, this object was in a so-called Apollo-class orbit that was mostly outside the Earth's orbit. Following the close approach, the Earth's gravitational attraction modified the object's orbit to an Aten-class orbit where the asteroid spends almost all of it a time inside the Earth's orbit. ...

Wow, I saw this with my own eyes. I didnt believe it at first, then I read up on it when I got home. It was moving VERYYYYYY fast, looked a bit closer than what is shown.
I saw a fireball at 9:19pm on Feb 5 going East over the Hudson River from Jersey City. It was low flying, but didn't look like it was going really fast (it took about 2 minutes to span the 3 mile river. So many people live in the area- I know I can't be the only person who saw this!
