The Moon and Saturn will share the same right ascension, with the Moon passing 0°22' to the south of Saturn. The Moon will be 20 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Cambridge, the pair will be visible in the dawn sky, rising at 01:19 (EDT) – 4 hours and 29 minutes before the Sun – and reaching an altitude of 25° above the southern horizon before fading from view as dawn breaks around 05:28.

The Moon will be at mag -12.1, and Saturn at mag 0.3, both in the constellation Sagittarius.

The pair will be close enough to fit within the field of view of a telescope, but will also 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 19h27m10s -21°53' Sagittarius -12.1 29'58"9
Saturn 19h27m10s -21°31' Sagittarius 0.3 17"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 104° from the Sun, which is in Aries at this time of year.
