Across much of the world, the open star cluster NGC 2451 (mag 2.8) in Puppis will be well placed in the evening sky in coming weeks. On 16 January it will reach its highest point in the sky at around midnight local time, and on subsequent evenings it will culminate four minutes earlier each day.
From Cambridge , however, it is not readily observable since it lies so far south that it will never rise more than 9° above the horizon.
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.
At magnitude 2.8, NGC2451 is visible to the naked eye, but best viewed through a pair of binoculars.
The position of NGC2451 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| NGC2451 | 07h45m10s | 37°58'S | Puppis | 2.8 | 37'30" |
The coordinates above are given in J2000.0.
