Neptune will be at mag 7.9, and 1 Ceres at mag 9.4, both in the constellation Aquarius.

A graph of the angular separation between Neptune 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
Neptune 23h18m50s -05°34' Aquarius 7.9 2"2
1 Ceres 23h18m50s -14°12' Aquarius 9.4 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 58° from the Sun, which is in Sagittarius at this time of year.
