The Moon and Saturn will make a close approach, passing within 2°50' of each other. The Moon will be 4 days old.

From Jacksonville , the pair will become visible at around 17:57 (EST), 34° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 21:37.

The Moon will be at mag -11.2; and Saturn will be at mag 0.4. Both objects will lie in the constellation Sagittarius.

They 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.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between the Moon and Saturn 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 19h58m30s 23°53'S Sagittarius -11.2 31'31"9
Saturn 19h57m00s 21°04'S Sagittarius 0.4 15"8

The coordinates above are given in J2000.0. The pair will be at an angular separation of 59° from the Sun, which is in Libra at this time of year.
