The open star cluster NGC 2451 (mag 2.8) 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 37°58'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 32°N.

From San Diego, it will be difficult to observe as it will appear no higher than 19° above the horizon. It will be visible between 22:04 and 01:23. It will become accessible around 22:04, when it rises to an altitude of 15° above your southern horizon. It will reach its highest point in the sky at 23:44, 19° above your southern horizon. It will become inaccessible around 01:23 when it sinks below 15° above your southern horizon.
