Wednesday July 12th the 18-day old waning gibbous 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 18-day old waning gibbous Moon will be over the south-southeast horizon an hour or so after sunset local time. The Moon will be in conjunction, and within about 2o from the outermost, (8th), planet Neptune.
