One relatively mundane effect not explicitly mentioned in the discussion
so
far that influences the frequency of halo effects seen about the moon is
that
the moon is not up all night like the sun is up all day, except when the
moon
is full. So this is an extra factor on top of the brightness effect that
serves to even more strongly emphasize the frequency of phenomena around
full
moon.
But I find that in one respect the lower intensity of the lunar orb is an
advantage: coronae are more often observable around the moon, or at least
they are more *comfortably* observable. Unless one regularly looks
directly
at the sun and wears extremely dark sunglasses (like I know Brian Skiff
does), the solar counterparts, though no doubt often present, are
practically unobservable due to the sun's intensity and the often very
bright clouds in which coronae are formed.
