The open star cluster M41 (NGC 2287; mag 4.5) in Canis Major will be well placed in the evening sky in coming weeks. On 2 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 San Diego , it is visible between 20:28 and 02:59. It will become accessible at around 20:28, when it rises to an altitude of 18° above your south-eastern horizon. It will reach its highest point in the sky at 23:43, 36° above your southern horizon. It will become inaccessible at around 02:59 when it sinks below 18° above your south-western horizon.

At a declination of 20°45'S, it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 49°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.
