The Triangulum galaxy (M33) will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +30°39', it is easiest to see from the northern hemisphere and cannot be seen from latitudes much south of 39°S.

From London (click to change), it will be visible all night. It will become visible at around 19:27 (BST) as the dusk sky fades, 27° above your eastern horizon. It will be lost to dawn twilight at around 06:07, 31° above your western horizon.

At magnitude 5.7, M33 is too faint to be seen with the naked eye from any but the very darkest sites, but is visible through a pair of binoculars or small telescope.

The precise position of M33 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M33 01h33m50s +30°39' Triangulum 5.7 1'02"

The coordinates above are given in J2000.0.
