Saturn and Neptune will share the same right ascension, with Saturn passing 30' to the south of Neptune.
From Jacksonville , the pair will become visible at around 18:31 (EDT), 23° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 3 hours and 19 minutes after the Sun at 20:51.
Saturn will be at mag 0.4, and Neptune at mag 8.0, both in the constellation Sagittarius.
The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.
A graph of the angular separation between Saturn and Neptune 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 |
| Saturn | 18h45m10s | 22°39'S | Sagittarius | 0.4 | 15"6 |
| Neptune | 18h45m10s | 22°09'S | Sagittarius | 8.0 | 2"2 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 49° from the Sun, which is in Libra at this time of year.
