December Moon at Descending Node

   Friday December 22nd the waxing crescent Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.

   On the day of the node crossing the 4.75-day old waxing crescent Moon will be over the southwestern horizon an hour or so after sunset local time.
