Qué es el azimutIn celestial navigation, what is the azimuth of a body?
Show the answer
Correct answer: d) The arc of the horizon between the north vertical or north cardinal point and the body’s vertical circle.
Why it is correct
Azimuth (Z) is a horizon coordinate: it is the arc of the true horizon measured from the North cardinal point (or the cardinal point of the observer’s latitude in quadrantal notation) to the body’s vertical circle.
Why the others are not
- a) Along the meridian we measure latitude or meridian zenith distance, not azimuth.
- b) Along the equator we measure hour angles, right ascension and sidereal hour angle.
- c) Azimuth is not measured along a parallel.
How to work it out in the exam
- Azimuth: arc of the horizon between the North cardinal point and the body’s vertical circle.
