Saturn and Neptune will share the same right ascension, with Saturn passing 1°08' to the south of Neptune.

From Cambridge, the pair will be visible in the morning sky, becoming accessible around 22:51, when they rise to an altitude of 10° above your eastern horizon. They will then reach its highest point in the sky at 03:51, 46° above your southern horizon. They will be lost to dawn twilight around 05:00, 44° above your south-western horizon.

Saturn will be at mag 0.6, and Neptune at mag 7.8, both in the constellation Pisces.

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 Saturn and Neptune 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 00h07m40s -01°46' Pisces 0.6 18"7
Neptune 00h07m40s -00°37' Pisces 7.8 2"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 132° from the Sun, which is in Cancer at this time of year.
