The Moon and Mercury will share the same right ascension, with the Moon passing 1°43' to the north of Mercury. The Moon will be 28 days old.
From Cambridge , the pair will be visible in the dawn sky, rising at 04:53 (EDT) – 1 hour and 38 minutes before the Sun – and reaching an altitude of 12° above the south-eastern horizon before fading from view as dawn breaks at around 06:08.
The Moon will be at mag -9.0, and Mercury at mag -0.7, both in the constellation Virgo.
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 | 14h06m30s | 8°43'S | Virgo | -9.0 | 33'20"5 |
| Mercury | 14h06m30s | 10°26'S | Virgo | -0.7 | 6"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 19° from the Sun, which is in Libra 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.
