Saturn and 1 Ceres will share the same right ascension, with Saturn passing 8°28' to the south of 1 Ceres.

From South El Monte , the pair will become visible at around 21:19 (PDT), 43° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 00:53.

Saturn will be at mag 0.8, and 1 Ceres at mag 8.6, both in the constellation Leo.

A graph of the angular separation between Saturn 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
Saturn 11h10m50s 7°31'N Leo 0.8 17"3
1 Ceres 11h10m50s 15°59'N Leo 8.6 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 76° from the Sun, which is in Taurus at this time of year.
