The Moon and Jupiter will make a close approach, passing within a mere 28.4 arcminutes of each other. The Moon will be 1 days old.
From Ashburn however, the pair will be visible from soon after it rises, at 07:51, until soon before it sets at 20:33. 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 -8.3; and Jupiter will be at mag -2.0. Both objects will lie in the constellation Pisces.
They will be close enough to fit within the field of view of a telescope, but will also 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 Jupiter 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 15° from the Sun, which is in Pisces 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.
