Venus and Saturn will share the same right ascension, with Venus passing 1°48' to the south of Saturn.
From Seattle, the pair will be difficult to observe as they will appear no higher than 13° above the horizon. They will become visible around 16:41 (PST) as the dusk sky fades, 13° above your south-western horizon. They will then sink towards the horizon, setting 2 hours and 16 minutes after the Sun at 18:33.
Venus will be at mag -4.0, and Saturn at mag 0.5, 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 Venus 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 30° from the Sun, which is in Ophiuchus 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.
