Apparently some folks heard meteors as they flashed by. The link is to a
NASA article which is light and yet technical. For the time impaired I
will sum up; The cause could be very low frequency radio generated by
turbulence in the ionized tail. The wave were strong enough to vibrate
nearby objects at audio frequencies.
