Summary: Bluish object hovering,then gone.

On the aforementioned night, my mother, my brother and I were taking a walk around our neighborhood.  We were almost home, and as I was looking up at the sky I noticed an intensly lit object.  It was small, because it was at a pretty high altitude.  It looked like two balls attached to each other by a rod (i.e. O-O)  It moved around erraticly with apparently random course.  Then, it streaked off to the south at a speed faster than any airplane would ever be able to reach.  Then it was gone.  I didn't say anything to my mom, but in later years I have mentioned it to my brother.
