The Hercules globular cluster (M13, NGC 6205) will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of +36°28', it is easiest to see from the northern hemisphere and cannot be seen from latitudes much south of 33°S.

From London (click to change), it will be visible all night. It will become visible at around 23:17 (BST) as the dusk sky fades, 65° above your south-eastern horizon. It will be lost to dawn twilight at around 02:41, 67° above your south-western horizon.

At magnitude 5.9, M13 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 M13 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
M13 16h41m40s +36°28' Hercules 5.9 0'16"

The coordinates above are given in J2000.0.
