The Moon, Venus and Saturn will make a close approach, passing within 3°49' of each other. The Moon will be 27 days old.
From Seattle, the trio will be difficult to observe as they will appear no higher than 15° above the horizon. They will be visible in the dawn sky, rising at 05:21 (PST) – 2 hours and 39 minutes before the Sun – and reaching an altitude of 15° above the south-eastern horizon before fading from view as dawn breaks around 07:36.
The Moon will be at mag -10.0; Venus will be at mag -4.0; and Saturn will be at mag 0.4. The trio will lie in the constellation Ophiuchus.
They 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 trio 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 trio will be at an angular separation of 34° from the Sun, which is in Sagittarius 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.
