The Moon and Saturn will make a close approach, passing within 3°27' of each other. The Moon will be 7 days old.
From Ashburn (click to change), the pair will become visible at around 19:16 (EDT) as the dusk sky fades, 26° above your southern horizon. They will then sink towards the horizon, setting 3 hours and 58 minutes after the Sun at 22:57.
The Moon will be at mag -11.5, and Saturn at mag 0.3, both in the constellation Ophiuchus.
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 closest approach 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 78° 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.
