Summary : Large, bright object crested over NW horizon moving very fast, my friend and I both saw the object, and another of my friends reported sightin the same object about 2 min. later coming from the same direction.

One large, luminous sphere apeared over the Northwest horizon directly in front of my friend and I, the diameter of the light itself would have easily covered the moon.The light was traveling over 100 MPH, at an altitude of only about 1000 feet yet did not make any sound.  If the object were a helicopter or an airplane, we would have easily heard it.  The light was similar in size and shape to the objects that appeared over Phoenix 2 weeks ago.  At the time, we were both students In Brookfield.  I was 10 years old, and my friend was 11 years old.  We had gone outside to "look for" UFOs, but we were not prepared for what we saw that night.  I am only submitting this information after the occurrance of a similar sighting over Phoenix, AZ.  Thank you.
