From ELPALLSKY 14OCT2011:
On October 17th, Asteroid 2009TM8, 5 to 11 meters in size, will pass between the moon and Earth. While there is no danger of the main body impacting Earth, debris generated by the collision which knocked the rock out of it's asteroid belt orbit may intersect Earth's orbit possibly generating an increase in green fireball activity a day or two before and after it's pass. Stay alert for increased fireball activity from 15OCT2011 to 20OCT2011.
