The open star cluster NGC 1981 (mag 4.6) in Orion's sword 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 -04°25', it is visible across much of the world; it can be seen at latitudes between 65°N and 74°S.
From Cambridge, it will be visible between 19:41 and 03:45. It will become accessible around 19:41, when it rises to an altitude of 17° above your south-eastern horizon. It will reach its highest point in the sky at 23:41, 43° above your southern horizon. It will become inaccessible around 03:45 when it sinks below 18° above your south-western horizon.
At magnitude 4.2, NGC1981 is tricky to make out with the naked eye except from a dark site, but is visible through a pair of binoculars or small telescope.
