Visit Worldwide Topsites

The beautiful Clavius crater by telescope.

Many things happens on the Moon? Of course not. But its appearance is changing every day. That makes amateur astronomers looking at it intensely whenever they have the opportunity, through an astronomical telescope. As a xerox laser passes over a page, so a Moon observer want to see all the phases.

Clavius​​ (225 km), it is impossible not to be noticed here. It is a complex crater. this one I described in numerous articles. I posted a picture below to locate its satellite craters inside and outside, easier. That picture is older, from 30 April 2012, but the lunar phase difference with the March 10, 2014 is not so big, and we can tell if we look at the small crater on the floor of Clavius​​, called Clavius J. From the edge a shadow starts towards the wall of Clavius​​. This shadow does not reach the wall in the picture from 2012, which means that the sun was upper, but in images from 2014, the shadow reaches the wall, which means that the sun was a little lower (at a lower angle).
