Jupiter and 1 Ceres will share the same right ascension, with Jupiter passing 2'12" to the south of 1 Ceres.
From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 20° above the horizon at dusk.
Jupiter will be at mag -1.9, and 1 Ceres at mag 9.0, both in the constellation Libra.
The pair will be close enough to fit within the field of view of a telescope, but will also 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 | 15h41m50s | 18°58'S | Libra | -1.9 | 33"6 |
| 1 Ceres | 15h41m50s | 18°55'S | Libra | 9.0 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 62° from the Sun, which is in Virgo at this time of year.
