    Poor choice of words, Lew!  I should have said observed, or noticed.

    On the "wet" coast, one or sometimes all of our Sandia All-sky camera
sites are clouded out.  One of the functions of this network is to alert
Sandia of a bright fireball event.  This would be another way of doing this
even if clouds are present.  I would think that the fireball would have to
be a very bright one to produce a noticable effect through a solid cloud
layer.  The full moon at -12.7 magnitude or so, is not bright enough to do
this unless the cloud layer is scattered or thin.  I expect that a thick
cloud layer would prevent detection even with a very bright fireball.
