The Moon and Mercury will share the same right ascension, with the Moon passing 3°07' to the south of Mercury. The Moon will be 2 days old.
From Ashburn however, the pair will be visible from soon after it rises, at 08:44, until soon before it sets at 18:25. Always take extreme caution when trying to make daytime observations of the Moon while the Sun is above the horizon.
The Moon will be at mag -8.9, and Mercury at mag -0.7, both in the constellation Capricornus.
The pair will be too widely separated to fit 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 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 | 20h18m30s | -24°14' | Capricornus | -8.9 | 32'58"5 |
| Mercury | 20h18m30s | -21°07' | Capricornus | -0.7 | 6"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 18° from the Sun, which is in Sagittarius 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.
