Disappearing moon

Bill J Gray May 21, 2003

Hi Dario,

Right-click on the Moon, then on "Display... Options". One of
those "options" is "Earthshine". By default, this is set at a point
that makes the unlit portions of the moon show up, but not at
a very bright level. It wouldn't surprise me if, depending on your
monitor settings, it didn't show up at all.

Set it to 100%, and you'd see a full moon sitting on top of
the sun (and it would be full no matter what phase the moon
was really at). Just set it to be a little fainter than that, and
you'll eventually track down a value you like. It may help to
do this for a first or last-quarter moon, so you can readily
compare lit vs unlit.
