Definition by Wikipedia :
A lunar eclipse occurs when the moon passes behind the earth so that the earth blocks the sun's rays from striking the moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon.
Did anyone of you actually see it ( should have been around 22 h here in Belgium)... I missed it.
