The Moon and Jupiter will share the same right ascension, with the Moon passing 4°17' to the north of Jupiter. The Moon will be 21 days old.
From Ashburn, the pair will be visible in the morning sky, becoming accessible around 02:02, when they rise to an altitude of 8° above your south-eastern horizon. They will then reach its highest point in the sky at 06:19, 33° above your southern horizon. They will be lost to dawn twilight around 06:53, 33° above your southern horizon.
The Moon will be at mag -11.8, and Jupiter at mag -2.0, both in the constellation Libra.
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 Jupiter 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 88° from the Sun, which is in Capricornus 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.
