My Bad! This should have been about Friday the 16th.
Thursday June 15th the 21.5-day old last 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 waning gibbous Moon will be over the southeast horizon at around 2 am CDT. The Moon will be in conjunction, and within about 2o from the outermost, (8th), planet Neptune.
