You won't find the moon in the evening sky now.  We'll tell you why --
after this.

November 5  Last Quarter Moon

Today the moon is at last quarter.  That means it's now three-quarters
of the way around in its monthly orbit of the Earth -- as measured from
one new moon to the next.  The next new moon will be a week from
today.

A last quarter moon is a morning moon.  You can look for the moon to
rise tonight right around midnight.  Since the moon is exactly last
quarter during the day today, tonight's moon will appear a little less
than half illuminated.  If you do see the moon around midnight -- when
it's just coming up over the eastern horizon -- notice how the lighted
portion of the moon points down toward the horizon.  Of course it's
pointing in the direction of the sun -- which is below you at midnight
-- beneath your feet -- illuminating the opposite side of the globe.

When Earth has turned so that you face the sun again -- in other words,
at dawn on Wednesday -- you can still notice that the illuminated
portion of the moon faces in the direction of the sun.  At dawn on
Wednesday, the moon will be approximately overhead, with its lighted
half facing east.

After midnight tonight, when the moon is up, look also for a bright
star near the moon.  That star is Regulus, the heart of the lion in the
constellation Leo.  You can see it after midnight tonight or tomorrow
night -- the star Regulus in the vicinity of the moon.
