Last month Mark Hancock was driving along Highway One when the sun was about to set. He pulled over and took a series of photos. This one looks just like a golden tornado, don't you agree?
I mentioned to Mark that these are the conditions to look for to see the green flash. He said there was a green flash that night but he missed getting the photograph. I can relate.
To see a green flash that occurred earlier this month, here's the link to Tom Eckle's photo: http://www.mendonomasightings.com/2012/03/08/the-green-flash-as-photographed-by-tom-eckles/
