Monday January 2nd the 5-day old 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 5-day old waxing crescent Moon will be over the southwest horizon, between Mars and Venus, at sunset local time. The outer planet Neptune is there but hidden by the Moon in this graphic. Click here to see a closeup image simulating a view with 10×50 binoculars.
