Green Flash

Submitter: unknown
Description: The Earth atmosphere is dispersive, i.e. light of different colors is refracted by different angles. The effect is most pronounced when the light travels a long distance through the atmosphere, e.g. the light of the Sun at sunrise or sunset. When only a thin sliver of the Sun is visible, it acts like the narrow slit of a spectrograph, so its rainbow colors are well-separated from each other. Thus it can happen, for a brief moment as the Sun rapidly sinks lower, that the light of the dying Sun appears green: The Green Flash.

NB: This phenomenon should not be confused with the fact that the rising/setting Sun appears red (and the sky is blue), which is caused by Rayleigh scattering.

Editors note: This picture appeared mysteriously, and for many years made little sense in the context of ASTRON or JIVE, especially since neither organization existed at the time. Until it was referred to by an AJDI in 2013, which is probably why you are now reading this. Since, after elimination of the impossible, whatever remains, however improbable, must be the truth, we can only conclude that it was dropped through a time-warp by a hyper-intelligent pan-dimensional being.
