NEO 2005 YU55 Close Approach May Bring Increased Meteor Activty
NEO (Near Earth Object) asteroid 2005 YU55 with a detected diameter of 400 meters is to safely pass the Earth on November 8, 2011.  This body with a close interaction may have accompanying debris that may encounter Earth as meteors or fireballs.  There is also a possibility that the Moon may experience increased meteor activity. Have your allsky cameras ready and get outside to observe if possible. If you have a telescope this object will be visible. Increased meteor/fireball activity will be 2-3 days on either side of Tuesday, November 8.  Another potential for increased meteor activity, asteroid 2011 UT91, will pass on 15NOV2011.
