The Moon and Uranus will make a close approach, passing within 1°06' of each other. The Moon will be 9 days old.

From Fairfield, the pair will be visible in the evening sky, becoming accessible around 16:47 (EDT) as the dusk sky fades, 43° above your south-eastern horizon. They will then reach its highest point in the sky at 19:02, 54° above your southern horizon. They will continue to be observable until around 00:44, when they sink below 8° above your western horizon.

The Moon will be at mag -12.3; and Uranus will be at mag 5.8. Both objects will lie in the constellation Pisces.

They will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between the Moon and Uranus around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 01h02m30s +04°47' Pisces -12.3 32'21"6
Uranus 01h01m10s +05°50' Pisces 5.8 3"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 108° from the Sun, which is in Sagittarius at this time of year.
