🔍 Key Concepts

• Celestial equator system vs. horizon system of coordinates • How hour angle and sidereal hour angle (SHA) relate to longitude • Meaning of symbols: Zn, SHA, LHA, and t in standard sight-reduction tables

💭 Think About

• Ask yourself: which of these quantities is measured around the celestial equator, similar to how longitude is measured around the Earth? • Which option is associated instead with the observer’s horizon (direction to the body) rather than with its position projected on the celestial equator? • For each symbol, recall whether it is an angle of direction (bearing/azimuth) or an hour angle (position on the celestial equator).

✅ Before You Answer

• Verify which of the options represents an azimuth (Zn) in the horizon system, not a celestial equator coordinate. • Confirm that SHA, LHA, and t are all types of hour angles measured westward along the celestial equator. • Before choosing, make sure the one you pick is the only quantity not defined on the celestial equator but instead in a different coordinate system.
