← HistoryWhich outcome occurs when an astrolabe plate (tympan), crafted for one latitude, is repeatedly used at a markedly different latitude?
A)Innacurate timing of lunar eclipses
B)Inaccurate planetary position calculations
C)Distorted sunrise/sunset time determination✓
D)Precise great circle distances visible
💡 Explanation
Sunrise/sunset determination becomes distorted because stereographic projection assumes tangency point corresponds to the observer's location; displacement creates angular errors in altitude/azimuth readings; therefore, correct sunrise data is offset, rather than precisely mapped celestial coordinates.
