Conjunction of the Moon and Saturn

The Moon and Saturn will share the same right ascension, with the Moon passing 15' to the south 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 Cambridge , the pair will be visible in the morning sky, becoming accessible around 23:41, when they reach an altitude of 11° above your eastern horizon. They will then reach their highest point in the sky at 04:24, 43° above your southern horizon. They will be lost to dawn twilight around 04:40, 43° above your southern horizon.

The Moon will be at mag -12.3, and Saturn at mag 0.8, both in the constellation Aquarius.

The pair will be close enough to fit within the field of view of a telescope, but will also 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 23h48m40s 3°54'S Aquarius -12.3 29'37"5
Saturn 23h48m40s 3°39'S Aquarius 0.8 18"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 125° from the Sun, which is in Cancer at this time of year.
