The Moon and Saturn will make a close approach, passing within 6°13' of each other. The Moon will be 25 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 02:08 (EDT) and reaching an altitude of 38° above the southern horizon before fading from view as dawn breaks at around 06:35.

The Moon will be at mag -11.3; and Saturn will be at mag 0.5. Both objects will lie in the constellation Virgo.

They 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.

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 13h37m00s 14°13'S Virgo -11.3 32'34"0
Saturn 13h44m40s 8°17'S Virgo 0.5 16"3

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