The Moon and M45 will make a close approach, passing within a mere 31.5 arcminutes of each other. The Moon will be 8 days old.
From Fairfield , the pair will be visible in the evening sky, becoming accessible around 17:58 (EST), 71° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 18:31, 72° above your southern horizon. They will continue to be observable until around 00:48, when they sink below 12° above your western horizon.
The Moon will be at mag -12.2; and M45 will be at mag 1.3. Both objects will lie in the constellation Taurus.
They will be a little too widely separated to fit comfortably 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 M45 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 | 03h46m50s | 24°36'N | Taurus | -12.2 | 31'58"3 |
| M45 | 03h47m30s | 24°06'N | Taurus | 1.3 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 102° from the Sun, which is in Capricornus at this time of year.
