Actual Report as Filed by Witness:

Fireball moving south to north in western sky lasting about 15 minutes, faded from sight in the distance.

At first I thought the fireball might be a meteor or an aircraft on fire. It moved slowly south to north across the western sky.  

When I first saw the fireball several small fireballs dropped and burned out as they fell. This led me to believe it may be an aircraft that was burning, it dropped one last small fireball that burned-out, then it continued north across the sky moving at a pace similar to a plane in the distance, until it faded from sight.
