March Meteors
c2015 Dirk Ross

There are currently 5 6 11 12 16 17 19 25 26 27 28 known NEO Asteroids discovered that will pass within approximately 10LD or less (LD stands for "Lunar Distance"), in the month of March; expect that 10 or more NEOs will be discovered before month end. Be ready for some bolide, fireball, and meteor activity!

  There are four are now FIVE including newly found 2014 YB35  to pass on 27MAR2015, small mountain-sized asteroids that will safely pass this month.
