🔍 Key Concepts

• Augmentation in celestial navigation relates to how the apparent size of a body changes with its altitude above the horizon. • The Nautical Almanac applies this correction when the body’s apparent semi‑diameter changes significantly. • Consider which body’s apparent size changes enough during an observation to require a specific correction table.

💭 Think About

• Ask yourself: for which of these bodies does the apparent size (and therefore semi‑diameter) vary the most as seen from Earth? • Which body is close enough to Earth that small changes in distance noticeably affect its apparent size during normal observations? • Think about which body in practice has the most detailed set of special corrections (parallax, horizontal parallax, etc.) in the Nautical Almanac.

✅ Before You Answer

• Verify which body has a specific table for augmentation of semi‑diameter in the Nautical Almanac. • Check which of these bodies is affected most by horizontal parallax and distance from Earth. • Confirm which body’s sight reduction process usually involves more individual corrections than the others listed.
