SUMMARY
The horizontal system of celestial coordinates allows observers to determine the location of the north celestial pole based on their latitude. For instance, at the North Pole (latitude 90), the north celestial pole is directly overhead at 90 degrees from the horizon. In contrast, an observer in San Francisco (latitude 38) would find the north celestial pole 38 degrees above the northern horizon. Observers located north of the equator cannot see the south celestial pole.
