Azimuth

This time of year, with the sun setting as quick as it is, we have to adjust the azimuth angle of our roof-top instruments daily so they remain in line with the sun and continue to collect accurate data.

When you are using an "altazimuth" telescope mount, the altitude is measured vertically from the ground at 0 degrees to the zenith straight overhead at 90 degrees, and the azimuth is measured horizontally, where 0 degrees points due north, 90 degrees is east, 180 degrees is south, and 270 degrees is west.

The navigator calculated the azimuth of the sun to determine their position at sea.

Astronomers use azimuth and altitude to describe the location of a star in the sky.

The surveyor recorded the azimuth between two mountain peaks for the new map.

The dome, being constructed of wood, was light by comparison with the rest of the structure, and the wheels which allowed it horizontal, or, as Swithin expressed it, azimuth motion, denied it a firm hold upon the walls; so that it had been lifted off them like a cover from a pot.
