The Andromeda galaxy (M31) will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +41°16', it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 28°S.

From Ashburn (click to change), it will be visible all night. It will become visible at around 19:55 (EST) as the dusk sky fades, 31° above your north-eastern horizon. It will be lost to dawn twilight at around 06:03, 35° above your north-western horizon.

At magnitude 3.5, 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' Andromeda 3.5 190'00"

The coordinates above are given in J2000.0.
