sorry, for some reason I was thinking the full moon was c. -18 but that
would probably be a little bright. (i was doing this in my head...) if
it's really -12.4 then about 2% of moon sounds right, which would be dim
shadows.  does venus cast visible shadows? i've heard of bright meteors
(-8, -10 range i would assume) casting them. who knows? so who among you
is going to be the first to turn your back on a monster-flare to look for
your shadow?
