Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 5°20' to the north of Saturn. The Moon will be 19 days old.

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

From Fairfield , the pair will be visible in the morning sky, becoming accessible around 21:51, when they reach an altitude of 9° above your eastern horizon. They will then reach their highest point in the sky at 03:57, 65° above your southern horizon. They will be lost to dawn twilight around 06:17, 51° above your south-western horizon.

The Moon will be at mag -12.3, and Saturn at mag -0.2, both in the constellation Taurus.

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

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 03h29m40s 21°49'N Taurus -12.3 29'30"0
Saturn 03h29m40s 16°28'N Taurus -0.2 19"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 128° from the Sun, which is in Virgo at this time of year.
