Well, all this talk of the causes of the blue moon are moot. Look at the
photo by Tom King in Watauga, Texas. In that photo you can see what
looks like an atmosphere forming a fuzzy blanket around the moon.
Obviously, the moon turns blue on those rare occassions when it acquires
and atmosphere!!!!!! :-)
