Question 1765Navigation General70% to pass
A body can only be observed at lower transit when _______________.
AI Explanation
The correct answer is C) the body is circumpolar.
A body can only be observed at lower transit when it is circumpolar, meaning the body never sets below the horizon for the observer's location. This occurs when the algebraic sum of the body's declination and the observer's latitude is less than 90 degrees. In this case, the body will always be above the horizon, and the lower transit will be observable.
The other options are incorrect because: A) the condition described does not specifically indicate a circumpolar body, B) high latitudes are not necessary for a body to be circumpolar, and D) the relationship between declination and latitude does not necessarily determine whether a body is circumpolar.
