Hewitt: I've seen a great many green flashes, and they are not restricted to the tropics. The expert is a former editor of Sky and Telescope, whose name I'll remember sometime, who told me that the best ones he'd seen were in Arizona. He explained that looking up over a mesa enhances the effect. I tried his idea, looking up above the mountains on Catalina, and saw a quite nice one. I asked Mike (I remembered part of his name) if I had really seen one above a cloud, and he assured me that I had. Bowditch notes that what's needed to see one is a clear day, a sharp horizon and a keen observer. Replace "horizon" with an equivalent flat contrasting something. I remember sitting on the beach at Moorea, looking west as the sun was setting, and I told Sibyl that we might see a green flash. She watched and, sure enough, there was one. Had it not occurred, she might never have looked again, likening it to the snipe hunt hoax. She's now an expert, arguing with me about whether the conditions are right to see one.
