Jupiter and Mars will share the same right ascension, with Jupiter passing 58' to the south of Mars.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From South El Monte , the pair will be visible in the dawn sky, rising at 00:46 (PDT) and reaching an altitude of 66° above the south-eastern horizon before fading from view as dawn breaks at around 06:22.

Jupiter will be at mag -2.1, and Mars at mag 0.9, both in the constellation Cancer.

The pair will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

A graph of the angular separation between Jupiter and Mars around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 77° from the Sun, which is in Virgo at this time of year.
