The Moon and Collinder 50 will make a close approach, passing within a mere 29.2 arcminutes of each other. The Moon will be 25 days old.

From Fairfield , the pair will be visible in the dawn sky, rising at 01:48 (EST) – 3 hours and 55 minutes before the Sun – and reaching an altitude of 34° above the eastern horizon before fading from view as dawn breaks at around 04:59.

The Moon will be at mag -11.2; and Collinder 50 will be at mag 1.0. Both objects will lie in the constellation Taurus.

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.

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 04h26m40s 16°28'N Taurus -11.2 32'13"6
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 58° from the Sun, which is in Cancer 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.
