🔍 Key Concepts

• Lunar observations (Moon sights) in celestial navigation • How Moon’s apparent size and shape change with phase and altitude • Which errors are biggest in practice versus mostly theoretical

💭 Think About

• Think about which option describes something that would consistently make it hard to take or use a Moon sight, not just a small computational correction • Ask yourself: Which of these problems would mainly affect the observation with the sextant, and which would mainly affect the mathematical reduction? • Consider your experience (or what you’ve read): When navigators talk about Moon sights being tricky, what practical issue do they most often complain about?

✅ Before You Answer

• Identify which choices deal with computational corrections (parallax, GHA, declination, augmentation) versus visual/observational difficulties • Recall that large, well-known corrections like horizontal parallax and augmentation are tabulated and routinely applied—are they usually considered a ‘major problem’ or just normal corrections? • Decide which option describes a difficulty that cannot be fully removed just by better tables or math, because it is inherent in what you see through the sextant

Question 1 of 20

The major problem with Moon sights is the __________.

approximations used in the solution caused by the variable horizontal parallax

rapid changes in GHA and declination introduce errors into the calculations

augmentation effect caused by the relatively short distance to the Moon

lack of a well defined limb during certain phases and positions in the sky
