The Moon, Jupiter and Saturn will make a close approach, passing within 2°56' of each other. The Moon will be 3 days old.
From Fairfield, the trio will become visible around 16:43 (EDT) as the dusk sky fades, 19° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 39 minutes after the Sun at 19:01.
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 trio 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 trio will be at an angular separation of 34° from the Sun, which is in Ophiuchus 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.
