The Moon and Mars will share the same right ascension, with the Moon passing 7°05' to the north of Mars. The Moon will be 12 days old.
From Ashburn, the pair will be visible in the evening sky, becoming accessible at around 20:55 (EST) as the dusk sky fades, 24° above your south-eastern horizon. They will then reach its highest point in the sky at 22:46, 29° above your southern horizon. They will continue to be observable until around 02:49, when they sink to 8° above your south-western horizon.
The Moon will be at mag -12.4, and Mars at mag -1.7, both in the constellation Libra.
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 Mars 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 145° from the Sun, which is in Taurus 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.
