The Moon and Saturn will share the same right ascension, with the Moon passing 3°04' to the north of Saturn. The Moon will be 16 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Ashburn (click to change), the pair will be visible in the morning sky, becoming accessible at around 21:37, when they rise 7° above your south-eastern horizon. They will then reach its highest point in the sky at 01:35, 28° above your southern horizon. They will be lost to dawn twilight at around 05:24, 8° above your south-western horizon.

The Moon will be at mag -12.5, and Saturn at mag 0.0, both in the constellation Ophiuchus.

The pair 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.

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 17h36m50s -18°53' Ophiuchus -12.5 29'25"1
Saturn 17h36m50s -21°58' Ophiuchus 0.0 18"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 173° from the Sun, which is in Taurus at this time of year.
