The open star cluster M47 (NGC 2422; mag 4.5) in Puppis 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 -14°28', it is easiest to see from the southern hemisphere; it can be seen at latitudes between 55°N and 84°S.

From Cambridge, it will be visible between 20:36 and 02:53. It will become accessible around 20:36, when it rises to an altitude of 18° above your south-eastern horizon. It will reach its highest point in the sky at 23:42, 33° above your southern horizon. It will become inaccessible around 02:53 when it sinks below 18° above your south-western horizon.
