The Moon and Collinder 50 will make a close approach, passing within 1°09' of each other. The Moon will be 24 days old.

From Cambridge , the pair will be visible in the dawn sky, rising at 01:07 (EDT) and reaching an altitude of 40° above the eastern horizon before fading from view as dawn breaks at around 04:55.

The Moon will be at mag -11.4; and Collinder 50 will be at mag 1.0. Both objects will lie in the constellation Taurus.

They will be too widely separated to fit 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 04h26m00s 17°07'N Taurus -11.4 32'09"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 66° 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.
