Across much of the world, the open star cluster IC 2581 (mag 4.0) in Carina will be well placed in the evening sky in coming weeks. On 27 February 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 San Diego , however, it is not observable because it lies so far south that it never rises above the horizon.

At a declination of 57°37'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 12°N.

At magnitude 4.0, IC2581 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 IC2581 is as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
IC2581 10h27m20s 57°37'S Carina 4.0 0'00"

The coordinates above are given in J2000.0.

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.
