The first total lunar eclipse in more than three years began at 2018 GMT, with the Moon totally immersed in the shadow of the Earth between 2244 and 2358 GMT. During "totality" the Moon took on a reddish hue; the only light reaching its surface by this stage had been filtered through Earth's atmosphere.
Now for the geeky bit:
Lunar eclipses occur when the Sun, Earth and Moon are in a near-perfect line in space. The Moon travels through the long cone-shaped shadow that the Earth casts in space. At totality, the only light reaching the Moon's surface has been refracted through the Earth's atmosphere. The appearance of the lunar surface varies according to how much dust is in the Earth's upper atmosphere. For example, following major volcanic eruptions, the Moon appears to be a deep red and almost invisible.
It took me ages to set up and get this photo so I hope you all enjoy it! ~Carol~
