The Compass Rose and Azimuth Write the direction and degrees in the boxes provided. 0 (360) E W S 180

Azimuth azimuth This is the direction of a celestial object, measured clockwise around the observer's horizon from north. So an object due north has an azimuth of 0°, one due east 90°, south 180° and west 270°.

Altitude altitude The angle of a celestial object measured upwards from the observer's horizon. Thus, an object on the horizon has an altitude of 0° and one directly overhead has an altitude of 90°. Altitude is also frequently referred to as "elevation"

Other vocabulary Celestial object –object outside the atmosphere (planet, star) Horizon-The line where the sky and the ground seem to meet. (sun rises and sets) Zenith- Point on the sky directly overhead. Elevation -indicate the height of the observer above sea-level. Constellation – a group of stars that appear to make a pattern

VOCABULARY Astronomy - study of universe, stars, planets, space Celestial object –object outside the atmosphere (planet, star) Horizon-The line where the sky and the ground seem to meet. (sun rises and sets) Azimuth –This is the direction of a celestial object, measured clockwise around the observer's horizon from north Altitude- The angle of a celestial object measured upwards from the observer's horizon Zenith- Point on the sky directly overhead. Elevation -indicate the height of the observer above sea-level. Apparent path of star – stars appear to move across the sky from east to west at a rate of 15 degree/hour because the earth is rotating Constellation – a group of stars that appear to make a pattern (88) Circumpolar stars – stars that appear to orbit around the poles and never set. Ecliptic – apparent path of the Sun against the background stars (12 constellations centered on ecliptic – zodiac)

The Astrolabe that the Portuguese navigators used on board ship to calculate the height of the Sun throughout the day. Using the astrolabe to measure the angle of the Sun above the horizon.
