   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 classical 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 reach a geocentric minimum illuminated fraction of its apparent disk on 2020 SEP 17 at 11:01 UT (06:01 CDT).

  Sharp eyed observers may attempt to spot the less than one-day-old Moon on September 17. Others should have better luck the following evening. See my New Moon Spotting chart above.
