The Moon and M44 will make a close approach, passing within a mere 16.9 arcminutes of each other. The Moon will be 15 days old.
From San Diego , the pair will be visible in the morning sky, becoming accessible around 18:55, when they reach an altitude of 16° above your eastern horizon. They will then reach their highest point in the sky at 00:27, 76° above your southern horizon. They will be lost to dawn twilight around 05:49, 17° above your western horizon.
The Moon will be at mag -12.8; and M44 will be at mag 3.1. Both objects will lie in the constellation Cancer.
They will be close enough to fit within the field of view of a telescope, but will also 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 | 08h40m10s | 19°23'N | Cancer | -12.8 | 33'25"2 |
M44 | 08h40m20s | 19°40'N | Cancer | 3.1 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 173° from the Sun, which is in Capricornus at this time of year.

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.
