The Moon and Mercury will share the same right ascension, with the Moon passing 6°06' to the south of Mercury. The Moon will be 28 days old.
From Fairfield , the pair will be difficult to observe as they will appear no higher than 11° above the horizon. They will be visible in the dawn sky, rising at 05:11 (EDT) – 1 hour and 28 minutes before the Sun – and reaching an altitude of 11° above the eastern horizon before fading from view as dawn breaks at around 06:15.
The Moon will be at mag -8.3, and Mercury at mag -0.3, both in the constellation Leo.
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 | 11h04m40s | 0°37'N | Leo | -8.3 | 29'57"0 |
| Mercury | 11h04m40s | 6°43'N | Leo | -0.3 | 7"3 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 16° from the Sun, which is in Virgo 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.
