The Moon and Venus will share the same right ascension, with the Moon passing 1°29' to the south of Venus. The Moon will be 28 days old.
From San Diego, the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will be visible in the dawn sky, rising at 05:42 (PDT) – 1 hour and 9 minutes before the Sun – and reaching an altitude of 9° above the south-eastern horizon before fading from view as dawn breaks around 06:35.
The Moon will be at mag -8.7, and Venus at mag -3.9, 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 Venus 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 17° from the Sun, which is in Sagittarius at this time of year.

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.
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.
