The Moon and Saturn will share the same right ascension, with the Moon passing 2°49' to the north of Saturn. The Moon will be 25 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 02:50 (EDT) – 2 hours and 27 minutes before the Sun – and reaching an altitude of 21° above the south-eastern horizon before fading from view as dawn breaks around 04:56.

The Moon will be at mag -11.3, and Saturn at mag 0.9, both in the constellation Pisces.

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 00h01m20s +00°42' Pisces -11.3 32'29"5
Saturn 00h01m20s -02°06' Pisces 0.9 16"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 60° from the Sun, which is in Taurus at this time of year.
