The globular cluster M2 (NGC 7089) in Aquarius will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -00°49', it is visible across much of the world; it can be seen at latitudes between 69°N and 70°S.

From London (click to change), it will be visible all night. It will become visible at around 21:58 (BST) as the dusk sky fades, 25° above your south-eastern horizon. It will be lost to dawn twilight at around 04:13, 24° above your south-western horizon.

At magnitude 6.5, M2 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.

The precise position of M2 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M2 21h33m20s -00°49' Aquarius 6.5 0'12"

The coordinates above are given in J2000.0.
