Which error increases substantially when navigating at high latitudes using a sextant during winter solstice?

💡 Explanation

When navigating at high latitudes during the winter solstice, refraction error increases because the lower solar altitude means light passes through more of the atmosphere, causing greater bending of light. Therefore refraction error becomes dominant, rather than parallax, index, or shade errors which depend on different geometric and environmental conditions.
