July 1994 Safford, Ariz. 3A.M. Bright Sphere with Gas-like contents moving in circular motion Sphere itself motionless.

Couldn't sleep, awoke stepped ot on sundeck and saw a very bright light approx. 7 miles away.  First thought was a helicopter landing at Safford Airport but light didn't move after observing approx. 10 min.  Couldn't find binoculars, set-up my cousins small telescope. I observed a large bright round ball approx. 20 ft. in diameter.
The inside of the ball was constant motion of gas-like substances(like electron activity around a nucleus) constantly moving around and around.  I woke up cousin and wife and they saw the same thing I observed.  For some reason after viewing this bright ball we all went to bed and next day we didn't even talk about it. 
Later that evening we went out to dinner and noticed a similar bright light over the near-bye Graham Mountains.  Suddenly it raced across the sky in the direction of Phoenix, Ariz.approx. 180 miles away, within 2-3 seconds.  Could still see the brightness at that distance, although smaller in size.  
My cousin, his wife and myself have never told any one about what we saw.  I really don't know why.  We are Professional, well educated individuals.  
This sighting was real and not a hoax!
Witness indicates that the date of the sighting is approximate.  PD
