The Moon and Venus will share the same right ascension, with the Moon passing 5°48' to the north of Venus. The Moon will be 4 days old.
From Ashburn, the pair will become visible at around 17:04 (EDT) as the dusk sky fades, 21° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 4 minutes after the Sun at 19:48.
The Moon will be at mag -10.5, and Venus at mag -4.2, both in the constellation Sagittarius.
The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
A graph of the angular separation between the Moon and Venus 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 44° from the Sun, which is in Ophiuchus 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.
