The Andromeda galaxy (M31; mag 4.4) will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.
At a declination of 41°16'N, it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 28°S.
From Fairfield, it will be visible all night. It will become visible around 19:41 (EDT), 33° above your north-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 00:55, 89° above your northern horizon. It will be lost to dawn twilight around 05:45, 36° above your north-western horizon.
At magnitude 3.4, M31 is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.
The position of M31 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| M31 | 00h42m40s | 41°16'N | Andromeda | 3.4 | 190'00" |
The coordinates above are given in J2000.0.
