The Moon and Saturn will share the same right ascension, with the Moon passing 2°37' to the north of Saturn. The Moon will be 28 days old.

From Ashburn (click to change), the pair will be difficult to observe as they will appear no higher than 10° above the horizon. They will be visible in the dawn sky, rising at 06:00 (EDT) – 1 hour and 29 minutes before the Sun – and reach an altitude of 10° above the south-eastern horizon before fading from view as dawn breaks at around 07:10.

The Moon will be at mag -9.0, and Saturn at mag 0.4, both in the constellation Sagittarius.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 18h11m50s -19°53' Sagittarius -9.0 29'23"0
Saturn 18h11m50s -22°31' Sagittarius 0.4 15"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 22° from the Sun, which is in Sagittarius at this time of year.
