Group,
Apparently, unlike the waxing Moon when the polar opening
shadows can best be seen the day or two before the half
Moon, to me they are more noticeable on the day or two after
while the Moon is waning. This morning there was a very clear
sky and saw the shadows created by the way the Sun and Moon
face each other. When they become more and more face-to-face
the Sunlight brightens up the opposite side of the indentation of
the Moon's polar opening and it looks round as a ball.
