1. Day 2 notes Ch. 1 second half Motion of the Moon and eclipses

2. Motion of the Moon and Phases of the Moon The development of the current model of the solar system began with careful measurement of the movement of the Sun and the Moon. To understand this, let’s review the motion and the phases of the Moon, as we currently understand them. When we watch the Moon, it’s shape changes from one night to the next:

22. Animation of the view from the dark side of the Moon, looking down on the Earth during a solar eclipse.

23. Eclipse Geometry is favorable close to the equinoxes.

24. Eclipse Tracks (also see NASA Eclipse page, Mr. Eclipse and Eclipser)NASA Eclipse pageMr. Eclipse Eclipser

28. Web page at NASA devoted to this eclipse (link)link

29. Example of a map of the eclipse path, showing the center line and boundaries of the region under the umbra (total) For the total eclipse of 29 March 2006

30. Transits occur when a planet crosses between the Earth and the Sun, so we see a dark spot cross the Sun. This can only happen with Venus link or Mercury link.link Occultations occur when the Moon blocks out (occults) a planet. linklink
