Green Flash
Green flashes and green rays are optical phenomena that occur shortly after sunset or before sunrise, when a green spot is visible, usually for no more than a second or two, above the sun, or it may resemble a green ray shooting up from the sunset point. Green flashes are a group of phenomena stemming from different causes, and some are more common than others. Green flashes may be observed from any altitude (even from an aircraft). They usually are seen at an unobstructed horizon, such as over the ocean, but are possible over cloud tops and mountain tops as well.
A green flash also may be observed in association with the Moon and bright planets at the horizon, including Venus and Jupiter.

Famous quotes containing the words green and/or flash:
“The old priest Peter Gilligan
Was weary night and day;
For half his flock were in their beds,
Or under green sods lay.”

“The legislator must be in advance of his age.
Across the mind of the statesman flash ever and anon the brilliant, though partial, intimations of future events.... Something which is more than fore-sight and less than prophetic knowledge marks the statesman a peculiar being among his contemporaries.”
—Woodrow Wilson (1856–1924)
