Locating the Celestial Pole In the northern Hemisphere, find the North Star Polaris by facing North. To get basic bearings at an observing location, take note of where the Sun rises (East) and sets (West) each day. After the site is dark, face North by pointing your left shoulder toward where the Sun set.
