The Moon and Mercury will share the same right ascension, with the Moon passing 3°13' to the north of Mercury. The Moon will be 2 days old.

From Fairfield, the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will become visible around 20:50 (EDT), 9° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 19 minutes after the Sun at 21:49.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -9.0, and Mercury at mag -0.2, both in the constellation Cancer.

The pair will be too widely separated to fit 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 08h44m00s +22°43' Cancer -9.0 30'18"6
Mercury 08h44m00s +19°30' Cancer -0.2 6"2

The coordinates above are given in J2000.0. The pair will be at an angular separation of 22° from the Sun, which is in Gemini at this time of year.
