The Moon and Saturn will share the same right ascension, with the Moon passing 1°59' to the north of Saturn. The Moon will be 12 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 evening sky, becoming accessible at around 20:44 (EST) as the dusk sky fades, 19° above your south-eastern horizon. They will then reach its highest point in the sky at 23:10, 28° above your southern horizon. They will continue to be observable until around 03:06, when they sink to 8° above your south-western horizon.

The Moon will be at mag -12.4, and Saturn at mag 0.0, both in the constellation Sagittarius.

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 18h15m50s -20°34' Sagittarius -12.4 29'30"1
Saturn 18h15m50s -22°34' Sagittarius 0.0 18"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 151° from the Sun, which is in Cancer at this time of year.
