This last lunar eclipse of the year will happen on Friday, October 18, 2013 and will be visible in Europe, Africa, Asia and the Middle East. It will be faintly visible on the east coast of the Americas as the moon passes partially through the earth’s shadow or penumbra. However, due to the fact that the Sun will still be visible, most of the eclipse action will be blocked because of the light from the Sun.
As the Moon passes through the earth’s shadow, the color of the moon changes and darkens to a reddish hue. The color changes are due to the Sun’s light passing through earth’s atmosphere which blocks out the ‘blue light’ emitted from the Sun letting only the reddish color light waves through.
This final lunar eclipse of this year will start at 7:51 p.m. EDT and will last four hours. While we won’t notice it much here in the US because it won’t be dark yet, it will be visible in the other areas mentioned above. The next lunar eclipse will be on April 15, 2014 and will be visible from the US.
