There Is A Green Flash At Sunset!!
Sue's Green Flash
Sue taught me about the "Green Flash"... and it DOES EXIST... we have seen it many times!
Explanation: Many think it is just a myth. Others think it is true but its cause is not known. Adventurers pride themselves on having seen it. It's a green flash from the Sun .
The truth is the green flash does exist and its cause is well understood. Just as the setting Sun disappears completely from view, a last glimmer appears startlingly green . The effect is typically visible only from locations with a low, distant horizon, and lasts just a few seconds.
A green flash is also visible for a rising Sun , but takes better timing to spot. A dramatic green flash was caught in the above photograph in 1992 from Finland . The Sun itself does not turn partly green, the effect is caused by layers of the Earth's atmosphere acting like a prism .
