🔍 Key Concepts

• Local Apparent Noon (LAN) and how it is used to find latitude • Meaning of Ho (observed altitude) and what 90° – Ho represents (the zenith distance of the Sun) • Relationship between horizon, zenith, pole, and Sun’s geographical position (GP) on the celestial sphere

💭 Think About

• When you do 90° – Ho at LAN, what angle are you actually finding on the celestial sphere, and between which two points is that angle measured? • Think about a basic sextant altitude: from what reference do you measure altitude, and what point is directly above you? How many degrees separate those two points? • Which of the choices describes a fixed 90° relationship that is always true for any observer, regardless of where the Sun is?

✅ Before You Answer

• Be clear on the definition of zenith (point directly overhead) and horizon (0° altitude reference for Ho). • Identify which answer choice describes an angular distance of exactly 90° that does not change with time, date, or Sun’s position. • Verify which pair of points is used in defining the observer’s altitude and zenith distance in basic celestial navigation diagrams.
