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
.
