Mercury and Saturn will share the same right ascension, with Mercury passing 55' to the south of Saturn.
From Fairfield however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be 0° below the horizon at dawn.
Mercury will be at mag -0.6, and Saturn at mag 0.8, both in the constellation Aquarius.
The pair will be a little too widely separated to fit comfortably 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 Mercury 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 12° from the Sun, which is in Aquarius at this time of year.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
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.
