Colure

[kә'ljuә]

Definition

(n.) One of two great circles intersecting at right angles in the poles of the equator. One of them passes through the equinoctial points, and hence is denominated the equinoctial colure; the other intersects the equator at the distance of 90¡ from the former, and is called the solstitial colure.
