Shadows play on the water and in the sky in this panoramic view of the April 4
total lunar eclipse over San Francisco's Golden Gate Bridge. Just within planet
Earth's shadow the Full Moon's disk is still easy to spot at its brief total
phase. The urban night skyscape was composed to cover the wide range of
brightness visible to the eye. The shortest total lunar eclipse of the century,
this eclipse was also the third in a string of four consecutive total lunar
eclipses, a series known as a tetrad. Coming in nearly six month intervals, the
previous two were last April 15 and October 8. The next and final eclipse in
the tetrad will be on September 28. This 2014-2015 tetrad is one of 8 total
lunar eclipse tetrads in the 21st century.
