Seen a couple of nights ago, a blurry setting Moon, chasing the Sun round the sky.

You can tell what angle the Moon is to the Sun because of the angle of the curve on the sunlit side. As the Moon waxes and wanes the position of the Sun can be worked out, full Moon=the Sun is on the other side of the Earth, a sliver of Moon, the Moon is in between the Earth and the Sun. Eclipse? If the Moon Eclipses the Sun it is directly between the other two bodies. If the Moon turns bright red its the Earth getting between the Moon and Sun, its only really then that you can see the curvature of the Moons surface, whichis usually so reflective that it looks bright and flat.

I guess this is the most number of times I’ve written ‘”Moon” in a blog!
