The Moon and Saturn will share the same right ascension, with the Moon passing 2°13' to the north of Saturn. The Moon will be 24 days old.
From Fairfield, the pair will be visible in the dawn sky, rising at 02:34 (EDT) – 3 hours and 40 minutes before the Sun – and reaching an altitude of 23° above the southern horizon before fading from view as dawn breaks around 05:56.
The Moon will be at mag -11.4, and Saturn at mag 0.3, both in the constellation Sagittarius.
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 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 72° from the Sun, which is in Aquarius 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.
