A Golden Gate Eclipse
Explanation: 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.

Not only can he do stunning deep sky photos, Rogelio stuns everyone with his fantastic skyscapes! Being located in cloudy UK, I was unfortunately unable to see the eclipse this year.
Also @ geckzilla, have you ever been to San Francisco? Do you have any interesting stories?
On a slightly related note, have you ever been to Canada?

I've been to San Francisco. I personally do not have any cool stories as the visit was uneventful. I saw the goats they employ to eat away at the hillside vegetation, though. Later I found out it was to keep the homeless from sheltering in the bushes of these nice neighborhoods. Life is pretty unfair. I have never been to Canada but I aspire to visit one day.
Just call me "geck" because "zilla" is like a last name.

I'm curious as to why they are considered consecutive eclipses if they are 6 months apart? I would think consecutive to mean that an eclipse occured at each full moon.

I think they mens 'consecutive' as in eclipses that are considered total.
But I could be wrong and hopefully someone will correct me while explaining it to you.

I believe the term "Consecutive" was used because there is only the possibility of an eclipse every 6 months at or near the equinoxes. Now I have seen one follow the other (Lunar/Solar) at a 2 week interval
