There Is A Green Flash At Sunset!!
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.
