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 17 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 Fairfield , however, it is not readily observable since it lies so far south that it will never rise more than 10° 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.

The circumstances of this event were computed using the DE430 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
