The moon is seen in the time around a total lunar eclipse in an area of Quito close to the equator, on April 15, 2014. People in most of North and South America were able to witness this year's first total lunar eclipse, which caused a 'blood moon' and was the first of four in a rare Tetrad of eclipses over the next two years.
