The globular cluster M12 (NGC 6218; mag 6.7) in Ophiuchus will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.

At a declination of -01°56', it is visible across much of the world; it can be seen at latitudes between 68°N and 71°S.

From Cambridge, it will be visible all night. It will become visible around 21:42 (EDT) as the dusk sky fades, 29° above your south-eastern horizon. It will then reach its highest point in the sky at 00:47, 45° above your southern horizon. It will be lost to dawn twilight around 03:44, 30° above your south-western horizon.
