In a Green Flash

As the sun sinks into the Pacific, its last light seems to glow green. This green flash, caused by light refracting in the atmosphere, is rarely seen. But Nigella Hillgarth, the director of the Birch Aquarium at the Scripps Institution of Oceanography in San Diego, got lucky one night. I often work late and have developed the habit of taking photos of the incredible sunsets over the Pacific from the Aquarium, Hillgarth told LiveScience. One evening, I was snapping away and caught the green flash as it appeared. I was hoping for a green flash, but was very excited when one actually happened and I caught it!
