The horizon coordinate system makes use of the coordinates azimuth and alitude. Azimuth is measured along the <1>. It is 0° at the <2> and increases eastwards. Altitude is measured along the <3> containing the object. It is 0° at the horizon and increases up to 90° at the <4>.
Complete the following table specifying the azimuth and altitude of some important positions in the horizon system from $location.
| Location | Azimuth | Altitude |

| North Celestial Pole | <5> | |
| Horizon $direction Point | <6> | <7> |
| Intersection of the Observer's Meridian and the Celestial Equator | <8> | <9> |
Meridinal altitude is the highest alitude that an object can achieve for that latitude. The star Betelguese has δ=7°. The meridinal altitude of Betelgeuse from the equator is <10>.
