    Doug Royer, you wrote:
    "Conditions, both  atmospheric and the observer's angle, have to be just
    perfect at the time of  setting for this event to even be witnessed. When it
    does happen it is  quickly over. A few seconds of time and it's gone. The
    Sun's upper limb is  already kissing or slightly below the horizon when this
    event does  happen.
    I just can't imagine how it can be done as stated. There are easier  ways to
    accomplish the same thing."
    
    Yeah, I agree. There's nothing  navigationally significant about the green
    flash, that I can think of, that  would make it any different from any other
    sunset. It's an attractive phenomenon  regardless. By the way, I, too, have
    "seen" the green flash, but like you I have  to wonder whether there was some
    wishful thinking involved since it was over so  quickly. There's no doubt that it's
    a real phenomenon --it can be photographed  and video-ed-- but it's not
    exactly an obvious thing.
