	Crepuscular - Wikipedia, the free encyclopedia
		Crepuscular is a term used to describe animals that are primarily active during the twilight.
		Crepuscular is thus in contrast with diurnal and nocturnal.
		Within the definition of crepuscular are the terms matinal (or "matutinal") and vespertine, denoting animals active in the morning (dawn) and evening (dusk) respectively.

	Crepuscular rays - Wikipedia, the free encyclopedia
		Crepuscular rays, in atmospheric optics, also known as sun rays, are rays of sunlight that appear to radiate from a single point in the sky.
		Crepuscular rays are near-parallel, but appear to diverge because of linear perspective.
		Crepuscular rays are usually red or yellow in appearance because the atmosphere acts as a giant lens, refracting low sunset rays into long curved paths passing through up to 40 times as much air than the rays from a high midday sun.

	Crepuscular Rays: sun rays converging on the horizon
		Crepuscular rays occur when objects such as mountain peaks or clouds partially shadow the sun's rays.
		Crepuscular rays appear to diverge outward from the setting sun, and are visible only when the atmosphere contains enough haze or dust particles so that sunlight in unshadowed areas can be scattered toward the observer.
		Crepuscular rays are often red or yellow in appearance because blue light from the sun is selectively scattered out of the beam by air molecules.

		Crepuscular rays are parallel columns of sunlit air looking as if they would diverge because of perspective effects.
		Crepuscular rays sometimes stretch across the whole sky and seem to converge in the antisolar point.
		Crepuscular rays are caused by small airborne particles of dust or tiny droplets of water or even by the molecules themselves which scatter sun- or moonlight.

		In the crepuscular lobby, a broad circle of monitors laid on their backs on the floor blinked up at a laser show spiraling across a tentlike scrim stretched just below the building's fled-out skylight.

	Crepuscular rays
		Crepuscular comes from the Latin crepusculum, which means twilight.
		Crepuscular rays can appear when the clouds (or terrain) that are responsible for the rays are below the horizon.
		The so-called crepuscular rays are solar rays cast on the purple red, while the sun is below the observer's horizon, and sometimes span the entire twilight sky towards the Earth's shadow band (the twilight wedge).

	The Weather Notebook \| Crepuscular Rays and Wedge
		Crepuscular means "twilight," and these are sometimes called "twilight rays." Owls, for example, are considered crepuscular creatures because they are usually spotted as the sun is near the horizon (they actually work all night, but we usually don’t see them then).
		When light from the sun passes through a window, or a broken layer of cloud, some of the light is scattered—that’s why these rays are visible only from the side.
		Crepuscular scatterings seem to fan out in wide rays, but that’s only an illusion: light from the sun is coming in, pretty much, parallel lines.
