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 2022 FEB 01 at 05:32 UT (JAN 31 at 23:32 CST).
Sharp eyed observers may attempt to spot the less than one-day-old Moon on February 1. Others should have better luck the following evening. See my New Moon Spotting chart above.
