Fig. 2
Trajectory of the observed Eudoxus crater for the 15 April 2014 lunar eclipse. The arrow on the trajectory indicates the moving direction of the crater. Here we choose two points on the trajectory (A and B) to indicate different eclipsing stages. Point A and B correspond to the Penumbra A and Penumbra B views sketched in Fig. 1. The figure is reproduced from the NASA eclipse website (http://eclipse.gsfc.nasa.gov/lunar.html).
