                 LATE JANUARY NEW MOON SPOTTING


It’s a challenge every month to spot the New Moon after sunset by naked eye (or eyeglasses) as early as possible. I use the term New Moon in its traditional sense of one’s first sighting of the Moon after its monthly solar conjunction (Dark Moon). The Dark Moon (which some call New Moon) will be in geocentric longitudinal conjunction with the Sun on 2017 JAN 28 at 00:07 UT (27 at 18:07 CST).


   Early sighting of a New Moon becomes easier for observers north of the tropics once past the time of the Winter Solstice due to the widening angle at which the ecliptic strikes the horizon at sunset. The Moon after sunset on January 28 will be a day old for North Americans, and some sharp eyed observers may be able to sight it. More folks should have success the following evening. See my New Moon preview graphics above.


Also above is a link to a panorama including all Diana’s Bows in 2017. Those are waxing crescent Moons about 10% illuminated and aged about three days. The name is a reference to the archery equipment of the ancient Roman Goddess of Hunting and the Moon. The graphic nicely illustrates how the season of the year affects the viewing of a waxing crescent Moon.
