Jupiter and 1 Ceres will share the same right ascension, with Jupiter passing 2°51' to the north of 1 Ceres.
From Jacksonville however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 18° above the horizon at dusk.
Jupiter will be at mag -1.9, and 1 Ceres at mag 9.2, both in the constellation Ophiuchus.
The pair 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 Jupiter and 1 Ceres 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 |
| Jupiter | 17h23m30s | 22°57'S | Ophiuchus | -1.9 | 33"1 |
| 1 Ceres | 17h23m30s | 25°49'S | Ophiuchus | 9.2 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 51° from the Sun, which is in Virgo at this time of year.
