The Moon and M44 will make a close approach, passing within 0°57' of each other. The Moon will be 24 days old.

From Seattle, the pair will be visible in the dawn sky, rising at 00:15 (PDT) and reaching an altitude of 61° above the southern horizon before fading from view as dawn breaks around 07:19.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -11.8; and M44 will be at mag 3.1. Both objects will lie in the constellation Cancer.

They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between the Moon and M44 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 Moon 08h41m00s +20°36' Cancer -11.8 32'04"4
M44 08h40m20s +19°40' Cancer 3.1 94'59"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 80° from the Sun, which is in Virgo 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.
