Total eclipse of the moon Wednesday night

Look out for a total eclipse of the moon Wednesday night.

The eclipse begins at 7:43 Central Standard Time. Totality begins at 9:01, and ends at 9:51. The midpoint of the eclipse will be at 9:26, and the whole thing will be over at 11:09.

Lunar eclipses are comparatively frequent, and are visible over a goodly chunk of the globe. In essence, Earth comes between the moon and the sun, enveloping the moon in its own shadow.

Not all lunar eclipses look the same. The Danjon Scale is used to describe the appearance of the moon at totality:

L=0: Very dark eclipse. Moon almost invisible, especially at mid-totality.
L=1: Dark Eclipse, gray or brownish in colouration. Details distinguishable only with difficulty.
L=2: Deep red or rust-colored eclipse. Very dark central shadow, while outer edge of umbra is relatively bright.
L=3: Brick-red eclipse. Umbral shadow usually has a bright or yellow rim.
L=4: Very bright copper-red or orange eclipse. Umbral shadow has a bluish, very bright rim.

Though not particularly rare- several total lunar eclipses are generally visible each year- they're very much worth the watching.
