Uranus and 1 Ceres will share the same right ascension, with Uranus passing 8°52' to the north of 1 Ceres.
From South El Monte , the pair will become visible at around 18:05 (PST), 41° above your south-western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 22:10.
Uranus will be at mag 5.9 in the constellation Pisces, and 1 Ceres at mag 9.1 in the neighbouring constellation of Cetus.
A graph of the angular separation between Uranus 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 |
| Uranus | 00h04m20s | 0°17'S | Pisces | 5.9 | 3"4 |
| 1 Ceres | 00h04m20s | 9°10'S | Cetus | 9.1 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 70° from the Sun, which is in Sagittarius at this time of year.
