History

Which positional outcome arose using an astrolabe to compute the time before standardized mean time?

A)Planetary altitude determination error
B)Variation in solar noon duration
C)Discrepancy in local time readouts
D)Irregular lunar phase interpretation

💡 Explanation

An astrolabe calculates local solar time using angular measurements; because the equation of time varies throughout the year, `analemma correction` occurs, resulting in the discrepancy between the astrolabe's solar time, and real mean time. Therefore, local time reading differs rather than the altitude being off.
