The Sculptor galaxy (NGC 253) will be well placed for observation. It will reach its highest point in the sky at around midnight local time.
At a declination of -25°17', it is easiest to see from the southern hemisphere but cannot be seen from latitudes much north of 44°N.
From Cambridge, it will be visible between 00:14 and 01:12. It will become accessible around 00:14, when it rises to an altitude of 21° above your southern horizon. It will reach its highest point in the sky at 00:43, 22° above your southern horizon. It will become inaccessible around 01:12 when it sinks below 22° above your southern horizon.
At magnitude 7.1, NGC253 is quite faint, and certainly not visible to the naked eye, but can be viewed through a pair of binoculars or small telescope.
The position of NGC253 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| NGC253 | 00h47m30s | -25°17' | Sculptor | 7.1 | 28'00" |

The circumstances of this event were computed using the DE405 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.
