The Moon and Saturn will share the same right ascension, with the Moon passing 2°03' to the north of Saturn. The Moon will be 8 days old.
From Ashburn, the pair will be visible in the evening sky, becoming accessible around 19:32 (EDT) as the dusk sky fades, 28° above your southern horizon. They will then reach its highest point in the sky at 19:34, 28° above your southern horizon. They will continue to be observable until around 23:24, when they sink below 7° above your south-western horizon.
The Moon will be at mag -11.9, and Saturn at mag 0.2, 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 coordinates above are given in J2000.0. The pair will be at an angular separation of 97° from the Sun, which is in Virgo at this time of year.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
