The Moon and Saturn will make a close approach, passing within 3°26' of each other. The Moon will be 16 days old.

From Fairfield , the pair will be visible between 20:45 and 05:26. They will become accessible at around 20:45, when they rise to an altitude of 10° above your south-eastern horizon. They will reach their highest point in the sky at 01:06, 37° above your southern horizon. They will become inaccessible at around 05:26 when they sink below 10° above your south-western horizon.

The Moon will be at mag -12.7; and Saturn will be at mag 0.1. Both objects will lie in the constellation Libra.

They 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.

At around the same time, the pair will also share the same right ascension – called a conjunction.

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

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 14h23m30s 15°02'S Libra -12.7 32'44"7
Saturn 14h26m50s 11°41'S Libra 0.1 18"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 177° from the Sun, which is in Aries at this time of year.
