The Moon and Venus will make a close approach, passing within a mere 45.0 arcminutes of each other. From some parts of the world, the Moon will pass in front of Venus, creating a lunar occultation. The Moon will be 27 days old.
From Fairfield however, the pair will be visible from soon after it rises, at 05:05, until soon before it sets at 15:00. Always take extreme caution when trying to make daytime observations of the Moon while the Sun is above the horizon.
The Moon will be at mag -9.5; and Venus will be at mag -4.0. Both objects will lie in the constellation Libra.
They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.
At around the same time, the pair will also share the same right ascension – called a conjunction.
A graph of the angular separation between the Moon and Venus around the time of closest approach is available here.
The positions of the pair at the moment of closest approach 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 24° from the Sun, which is in Ophiuchus at this time of year.

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.
