Friday May 19th the 22.6-day old last quarter 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 last quarter Moon will be over the southeast horizon at sunrise local time. Venus and Mercury are also visible over the eastern horizon.
