🔍 Key Concepts

• Nautical Almanac Sun Correction Tables (front of the book) • Differences between physical/optical effects: refraction, parallax, semidiameter, irradiation • Which effects are explicitly listed and tabulated for sun sights

💭 Think About

• When you take a sextant altitude of the Sun, what standard corrections do you normally apply before getting the observed altitude? • Look at a sample Nautical Almanac: which of these four terms do you actually see named in the Sun correction tables? • Which of these is more of an optical illusion or physiological effect rather than a strictly geometric/astronomical correction?

✅ Before You Answer

• Be sure which items are printed as column headings in the Sun correction tables (check a real Nautical Almanac if possible). • Decide which effect is primarily due to Earth’s atmosphere versus the observer’s eye/brain. • Confirm which corrections are part of the normal sequence: index error, dip, refraction, parallax, semidiameter — then see which one doesn’t quite fit.
