Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 53' to the north of Saturn. The Moon will be 11 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 evening sky, becoming accessible around 18:39 (EDT), 45° above your eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 21:51, 71° above your southern horizon. They will continue to be observable until around 04:22, when they sink below 9° above your western horizon.

The Moon will be at mag -12.6 in the constellation Taurus, and Saturn at mag -0.4 in the neighbouring constellation of Orion.

The pair will be a little too widely separated to fit comfortably 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 05h54m10s 23°22'N Taurus -12.6 32'53"9
Saturn 05h54m10s 22°29'N Orion -0.4 20"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 133° from the Sun, which is in Capricornus at this time of year.
