The Moon and Saturn will share the same right ascension, with the Moon passing 1°46' to the north of Saturn. The Moon will be 15 days old.
From Cambridge, the pair will be visible between 21:05 and 04:25. They will become accessible at around 21:05, when they rise 7° above your south-eastern horizon, and then reach its highest point in the sky at 00:47, 25° above your southern horizon. They will become inaccessible at around 04:25 when they sink to 8° above your south-western horizon.
The Moon will be at mag -12.5, and Saturn at mag 0.0, both in the constellation Sagittarius.
The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
A graph of the angular separation between the Moon and Saturn around the time of closest approach is available here.
The positions of the two objects at the moment of conjunction will be as follows:
|Object||Right Ascension||Declination||Constellation||Magnitude||Angular Size|
The coordinates above are given in J2000.0. The pair will be at an angular separation of 177° from the Sun, which is in Gemini at this time of year.

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.
