When Eclipses Occur

In order to have an eclipse, these must hold:
  1. The Moon must be in the same plane as the Earth and the Sun.
  2. The line of nodes must point at the Sun
These hold true in Points A and C in the Earth's rotation.

Otherwise, whenever the Moon and the Sun are on the same side of the Earth, the Moon would either be above or below the Sun as viewed from the Earth.

These are Points B and D in the Earth's rotation.
