🔍 Key Concepts

• Effect of a vessel’s motion on observed altitude near meridian passage (LAN) • How north–south vs east–west courses change your latitude during the sight • Relationship between maximum altitude and the instant of meridian transit for a moving observer

💭 Think About

• Ask yourself: In which situation will your position be changing most in latitude while you are taking a string of sights around LAN? • If your latitude is changing during the observation, what does that do to the apparent altitude curve—can it shift or flatten the maximum? • Which answer choice describes a condition where the body’s change in altitude due to your own motion might compete with or mask the natural maximum at transit?

✅ Before You Answer

• Identify which options describe vessel motion versus those that describe only declination/latitude relationships • Consider under which option the change of latitude during a few minutes would be greatest • Before choosing, ask: In this case, would the observed maximum altitude still reliably mark true LAN, or could it be significantly distorted?
