Hi,  I asked around and nobody heard any sounds except an observer
in the north of the state who claimed to hear a "hissing sound".  This
type of comment does occur on some Fireball sightings.  But no rattling
of windows or the like.  So alas,  I'll just have to say the measured "noise"
at the time of satellite entry will be put in the Hmmmm basket.  I do agree
that the magnet effect is not really possible given the 1/r^3 decline in the
magnet strength with distance.  Anyhow  unit the next event.

Thanks to John Hernlund and Ken Navarre.
