Which consequence occurs when using sextants during cloudy afternoons?

💡 Explanation

Less light reaches the observer because clouds scatter incoming rays, and reduces the sea horizon visibility, therefore smaller angles must be interpolated, rather than directly observable celestial bodies. Increased error results.
