The open star cluster NGC 1981 in Orion's sword will be well placed for observation. 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 19:43 and 03:47. It will become accessible around 19:43, when it rises to an altitude of 17° above your south-eastern horizon. It will reach its highest point in the sky at 23:43, 43° above your southern horizon. It will become inaccessible around 03:47 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.
The position of NGC1981 is as follows:
