Correct answer: a) The observer’s latitude.

The observer’s projection onto the celestial sphere is the zenith (Z). The arc of the observer’s celestial meridian between the celestial equator (Q) and the zenith (Z) equals the observer’s latitude (φ = QZ).
Why the others are not
- b) Longitude is measured along the equator from the Greenwich meridian.
- c) The arc from zenith to the elevated pole is colatitude (90° − φ).
- d) Azimuth is an arc of the horizon referring to a celestial body.
How to work it out in the exam
- Celestial meridian arc between equator and observer’s zenith = latitude.
