The Moon and Collinder 50 will make a close approach, passing within a mere 33.1 arcminutes of each other. The Moon will be 11 days old.

From Cambridge , the pair will be visible in the evening sky, becoming accessible around 17:22 (EST), 44° above your eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 20:14, 63° above your southern horizon. They will continue to be observable until around 02:07, when they sink below 11° above your western horizon.

The Moon will be at mag -12.6; 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 04h26m30s 16°32'N Taurus -12.6 32'45"4
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 Sagittarius 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.
