The Moon and Mercury will share the same right ascension, with the Moon passing 48' to the south of Mercury. The Moon will be 1 days old.
From Fairfield however, the pair will not be readily observable since they will be very close to the Sun, at a separation of only 13° from it.
The Moon will be at mag -8.2, and Mercury at mag 2.7, both in the constellation Virgo.
The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between the Moon and Mercury 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 Moon | 11h49m20s | 4°19'S | Virgo | -8.2 | 33'00"1 |
| Mercury | 11h49m20s | 3°30'S | Virgo | 2.7 | 10"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 13° from the Sun, which is in Leo at this time of year.

Warning
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.
