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:
“Meanwhile the mind from pleasure less
Withdraws into its happiness;
The mind, that ocean where each kind
Does straight its own resemblance find;
Yet it creates, transcending these,
Far other worlds and other seas,
Annihilating all that’s made
To a green thought in a green shade,”
—Andrew Marvell (1621–1678)
“I think that in the swift white mind’s brain
Neurons flash images of a world
Undead and deathless, burgeoning again.
I think that Spring will come this way, unfurled.”
—Allen Tate (1899–1979)
