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) was in geocentric longitudinal conjunction with the Sun on 2017 JUN 24 at 02:31 UT (23 at 21:31 CDT).
The Moon after sunset on June 24 was about a day old for North Americans. However, after the time of the summer solstice, the sharp angle at which the ecliptic strikes the horizon after sunset makes spotting a young Moon difficult. The waxing crescent Moon this month running south of the ecliptic is also unhelpful. More observers should have had luck on June 25. See my New Moon Spotting 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.
