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 DEC 18 at 06:30 UT (00:30 CST).
Some sharp-eyed observers may be able to set personal records sighting the 2/3-day-old Moon on December 18. The rest of us may have better luck during the following evening. See my New Moon Spotting graphics listed 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.
