No matter how many times I chant:

Rain, rain go away
Come again another day …

the skies take no notice.

So tonight I’m studying the photos I took before, and consulting Moon maps, looking for the features Greg pointed out in his comment.

First target: Plato

Now here’s a crater with a difference. The first impression is that it is not light coloured like the ones we looked at so far. The term used for how light or dark a feature is, is albedo which means the reflecting power of a surface. Plato has a low albedo, unlike Copernicus which has a high albedo. Though Plato is an impact crater, it has a low albedo because it is lava-filled.

Plato, located in a high albedo area, is distinctive and easily visible on the northeastern shore of the Sea of Showers and at the western extremity of the lightly coloured Alps mountain range. To the north lies the wide stretch of the Sea of Cold.
