lunar eclipse



A total lunar eclipse occurs when the full moon passes into the shadow of the Earth. The Earth blocks any direct sunlight from reaching the Moon, causing a total lunar eclipse.

Partial lunar eclipses occur when the Sun, Earth, and Moon are not perfectly aligned and only a portion of the Moon enters into the Earth's umbral shadow.

Everyone on the night hemisphere of the Earth can see a total lunar eclipse. Roughly 35% of all lunar eclipses in a year are total eclipses. 





Here is the timetable of aspects of the eclipse this time around (October 8th), as seen from Boulder; all times are local Mountain Daylight Time.
