[AZ-Observing] Re: BOLIDE! (photo!)

What is the 'contemporary' definition of a bolide?  The definition I
have is:
"A fireball accompanied by one or more audible explosions, often
associated with meteorite falls...Many shock waves may be set up if
considerable fragmentation occurs, causing a rumbling noise which
follows the first major fragmentation"

This definition does not say anything about color.  So far no one has
said they heard an explosion (or did I just miss it? - someone said they
heard some sputtering).  Is this object really a bolide?  Is one or more
explosions assumed to exist even when not heard if it looks and feels
like a bolide to experienced observers?  Since it was near polaris, my
guess is that it was somewhere between 30-90 miles from the observer (in
a straight line), and so maybe it would not be possible to hear an
explosion.
