The Moon and M45 will make a close approach, passing within 0°19' of each other. The Moon will be 11 days old.
From Fairfield, the pair will be visible in the evening sky, becoming accessible around 17:03 (EDT) as the dusk sky fades, 45° above your eastern horizon. They will then reach its highest point in the sky at 20:22, 72° above your southern horizon. They will continue to be observable until around 03:09, when they sink below 7° above your north-western horizon.
The Moon will be at mag -12.5; and M45 will be at mag 1.3. 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 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 coordinates above are given in J2000.0. The pair will be at an angular separation of 130° from the Sun, which is in Sagittarius at this time of year.
