Show the answer
Correct answer: b) The pole that has the same name (North or South) as the observer’s latitude.
Why it is correct
For any observer off the equator, one of the two celestial poles lies above the true horizon (at an altitude equal to the observer’s latitude): this is the elevated pole, which always has the same name (North or South) as the observer’s latitude. The opposite pole below the horizon is the depressed pole.
Why the others are not
- a) The projection of the observer onto the celestial sphere is the zenith.
- c) The elevated pole depends on the observer’s latitude, not on the observed body’s declination.
- d) The celestial axis passes directly through both celestial poles.
How to work it out in the exam
- Elevated celestial pole: the pole above the horizon having the same name as the observer’s latitude.
