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:
“Now the bright morning star, day’s harbinger,
Comes dancing from the east, and leads with her
The flow’ry May, who from her green lap throws
The yellow cowslip and the pale primrose.
Hail, bounteous May, that dost inspire
Mirth and youth and warm desire!
Woods and groves are of thy dressing,
Hill and dale doth boast thy blessing.”
—John Milton (1608–1674)
“We cannot know how much we learn
From those who never will return,
Until a flash of unforeseen
Remembrance falls on what has been.”
—Edwin Arlington Robinson (1869–1935)
