The Moon and Mercury will share the same right ascension, with the Moon passing 7°05' to the south of Mercury. The Moon will be 28 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 12° from it.
The Moon will be at mag -8.3 in the constellation Capricornus, and Mercury at mag 2.6 in the neighbouring constellation of Aquarius.
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 | 21h09m00s | 19°53'S | Capricornus | -8.3 | 33'25"0 |
| Mercury | 21h09m00s | 12°48'S | Aquarius | 2.6 | 10"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 14° from the Sun, which is in Capricornus at this time of year.
