The Moon and Collinder 50 will make a close approach, passing within a mere 43.2 arcminutes of each other. The Moon will be 19 days old.
From Fairfield , the pair will be visible in the morning sky, becoming accessible around 22:15, when they reach an altitude of 11° above your eastern horizon. They will then reach their highest point in the sky at 04:07, 64° above your southern horizon. They will be lost to dawn twilight around 06:17, 52° above your south-western horizon.
The Moon will be at mag -12.5; and Collinder 50 will be at mag 1.0. 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 Collinder 50 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 | 04h26m20s | 16°42'N | Taurus | -12.5 | 32'33"0 |
| Collinder 50 | 04h27m00s | 16°00'N | Taurus | 1.0 | 0"0 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 128° from the Sun, which is in Virgo at this time of year.
