Across much of the world, the Omicron Velorum open star cluster (IC 2391; mag 2.5) in Vela will be well placed in the evening sky in coming weeks. On 31 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 Ashburn , however, it is not observable because it lies so far south that it never rises above the horizon.

At a declination of 53°02'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 16°N.

At magnitude 2.5, IC2391 is visible to the naked eye, but best viewed through a pair of binoculars.

The position of IC2391 is as follows:

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.
