Jupiter and 1 Ceres will share the same right ascension, with Jupiter passing 2°43' to the south of 1 Ceres.
From South El Monte , the pair will be visible in the dawn sky, rising at 02:57 (PDT) – 3 hours and 46 minutes before the Sun – and reaching an altitude of 26° above the south-eastern horizon before fading from view as dawn breaks at around 05:41.
Jupiter will be at mag -1.9, and 1 Ceres at mag 8.9, 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 | 17h02m40s | 22°08'S | Ophiuchus | -1.9 | 33"0 |
| 1 Ceres | 17h02m40s | 19°25'S | Ophiuchus | 8.9 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 55° from the Sun, which is in Capricornus at this time of year.
