Show the answer
Correct answer: a) Along the body’s vertical semicircle, from the horizon to the body.
Why it is correct
The true altitude (Ho) of a celestial body is the arc of its vertical semicircle measured from the true horizon to the body, from 0° to 90° (positive above the horizon and negative below it).
Why the others are not
- b) An almucantar is parallel to the horizon; every point on it already has the same altitude.
- c) The body’s almucantar passes through the body itself, so that arc would be zero.
- d) Option a) is correct.
How to work it out in the exam
- Altitude of a body: arc of the vertical semicircle measured from the horizon to the body.
