The Moon and Jupiter will make a close approach, passing within 2°33' of each other. The Moon will be 21 days old.
From Washington, the pair will be visible in the morning sky, becoming accessible around 01:07, when they reach an altitude of 7° above your eastern horizon. They will then reach their highest point in the sky at 06:03, 45° above your southern horizon. They will be lost to dawn twilight around 07:26, 41° above your south-western horizon.
The Moon will be at mag -12.0; and Jupiter will be at mag -2.1. Both objects will lie in the constellation Virgo.
They 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 Jupiter around the time of closest approach is available here.
The positions of the pair 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 96° from the Sun, which is in Sagittarius at this time of year.

The circumstances of this event were computed using the DE430 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.
