The Moon and Saturn will share the same right ascension, with the Moon passing 1°46' to the north of Saturn. The Moon will be 15 days old.

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

From Ashburn, the pair will be visible between 21:16 and 05:05. They will become accessible at around 21:16, when they rise 7° above your south-eastern horizon, and then reach its highest point in the sky at 01:12, 28° above your southern horizon. They will become inaccessible at around 05:05 when they sink to 8° above your south-western horizon.

The Moon will be at mag -12.5, 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 18h24m00s -20°41' Sagittarius -12.5 29'30"5
Saturn 18h24m00s -22°28' Sagittarius 0.0 18"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 177° from the Sun, which is in Gemini at this time of year.
