The globular cluster M15 (NGC 7078) in Pegasus will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +12°10', it is easiest to see from the northern hemisphere; it can be seen at latitudes between 82°N and 57°S.

From London (click to change), it will be visible all night. It will become visible at around 22:00 (BST) as the dusk sky fades, 36° above your south-eastern horizon. It will be lost to dawn twilight at around 04:11, 35° above your south-western horizon.

At magnitude 6.4, M15 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 M15 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M15 21h30m00s +12°10' Pegasus 6.4 0'12"

The coordinates above are given in J2000.0.
