The Moon and Mercury will share the same right ascension, with the Moon passing 6°35' to the south of Mercury. The Moon will be 1 days old.
From Fairfield , the pair will become visible at around 19:36 (EST), 12° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 33 minutes after the Sun at 20:47.
The Moon will be at mag -8.6, and Mercury at mag -0.6, both in the constellation Pisces.
The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.
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 | 01h36m50s | 5°42'N | Pisces | -8.6 | 32'43"8 |
| Mercury | 01h36m50s | 12°18'N | Pisces | -0.6 | 6"9 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 16° from the Sun, which is in Pisces at this time of year.
