The globular cluster M12 (NGC 6218) in Ophiuchus will be well placed for observation. It will reach its highest point in the sky at around midnight local time.

At a declination of -01°57', it is visible across much of the world; it can be seen at latitudes between 68°N and 71°S.

From London (click to change), it will be visible all night. It will become visible at around 23:21 (BST) as the dusk sky fades, 32° above your south-eastern horizon. It will be lost to dawn twilight at around 02:38, 32° above your south-western horizon.

At magnitude 6.6, M12 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.
