Sunday night lunar eclipse

Sunday night was perfect for viewing the lunar eclipse. This progression was taken by Dick Richards.

A lunar eclipse (also known as a blood moon) occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can occur only the night of a full moon.
