The Moon and Saturn will make a close approach, passing within 1°31' of each other. The Moon will be 19 days old.

From Cambridge , the pair will be visible in the morning sky, becoming accessible around 20:42, when they reach an altitude of 9° above your eastern horizon. They will then reach their highest point in the sky at 02:57, 65° above your southern horizon. They will be lost to dawn twilight around 06:32, 38° above your western horizon.

The Moon will be at mag -12.6; and Saturn will be at mag -0.3. Both objects will lie in the constellation Taurus.

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 03h54m50s 16°25'N Taurus -12.6 31'57"3
Saturn 03h53m10s 17°53'N Taurus -0.3 20"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 142° from the Sun, which is in Virgo at this time of year.
