The open star cluster M47 (NGC 2422) in Puppis will be well placed for observation. 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 Ashburn (click to change), it will be visible between 20:45 and 03:32. It will become accessible at around 20:45, when it rises 18° above your south-eastern horizon, and then reach its highest point in the sky at 00:11, 36° above your southern horizon. It will become inaccessible at around 03:32 when it sinks to 18° above your south-western horizon.
At magnitude 4.4, M47 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 M47 is as follows:
