Happy Equinox, a little early.
This afternoon, to my pleasure, I checked the Portable Stonehenge with the angle between the Sun and the Moon and it was spot on. Lately, especially during the Winter Months when it's cloudy, the moon peg gets a little off. But today, when I held Portable Stonehenge up so that the sun peg's shadow crossed through the center of the board and then sited over the center and the moon's peg, the thin crescent moon was right on the moon peg's top.
It sounds more complicated than it is.
Anyway, out to look at the crescent moon before it goes behind a hill.
