Conjunction of the Moon and Mercury

The Moon and Mercury will share the same right ascension, with the Moon passing 35' to the south of Mercury. The Moon will be 28 days old.

From Cambridge , the pair will be visible in the dawn sky, rising at 05:03 (EST) – 1 hour and 48 minutes before the Sun – and reaching an altitude of 12° above the south-eastern horizon before fading from view as dawn breaks at around 06:27.

The Moon will be at mag -8.9, and Mercury at mag -0.6, both in the constellation Libra.

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 the Moon and Mercury 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
The Moon 15h08m50s 15°50'S Libra -8.9 30'45"7
Mercury 15h08m50s 15°15'S Libra -0.6 6"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 19° from the Sun, which is in Ophiuchus at this time of year.
