There are currently eight known NEO Asteroids discovered that will pass within approximately 10LD or less (LD stands for "Lunar Distance"), in the month of December 2016. I expect that 10-35 NEOs or more, 10LD or less, will be discovered before month end.

Expect some spectacular bolides, fireballs, and meteors this month and especially large ones 3-5 days before and following the passing of the less than 10LD NEOs and fifteen small mountain-sized NEO asteroids, diameters ranging from 400m-2.0km, that will safely pass this month.
