The relative direction of diurnal motion in the [[Northern Celestial Hemisphere]] are as follows:
* Facing north, below [[Polaris]]: rightward, or eastward
* Facing north, above Polaris: leftward, or westward
* Facing south: rightward, or westward

Thus, northern [[circumpolar star]]s move counter[[clockwise]] around [[Polaris]], the north [[pole star]].

At the [[North Pole]], the [[cardinal direction]]s do not apply to diurnal motion. Within the circumpolar circle, all the stars move simply rightward, or looking directly overhead, counterclockwise around the [[zenith]], where Polaris is.

[[Southern Celestial Hemisphere]] observers are to replace north with south, left with right, and Polaris with [[Sigma Octantis]], sometimes called the south pole star. The circumpolar stars move clockwise around Sigma Octantis. East and west are not interchanged.

As seen from the [[Equator]], the two [[celestial pole]]s are on the horizon due north and south, and the motion is counterclockwise (i.e. leftward) around Polaris and clockwise (i.e. rightward) around Sigma Octantis. All motion is westward, except for the two fixed points.
