During a celestial navigation exercise for determining longitude at sea, a Master utilizes the noon sight method. Assuming a perfectly functioning chronometer with no error and an ideal horizon, what fundamental celestial body's observation is absolutely critical for this specific method to yield an accurate longitude?
A Mate is tasked with plotting a fix using celestial observations. They have successfully measured the altitude of Jupiter and Sirius. To accurately determine the vessel's position, what additional critical piece of information is required for *each* observation, beyond the observed altitude and the sextant's index error?
When calculating a celestial line of position (LOP) using an assumed position (AP) and a star sight, the computed altitude (Hc) is found to be 35° 10.0', and the observed altitude (Ho) is 35° 15.0'. The calculated azimuth (Zn) is 045°. If the AP's latitude is 40°N and longitude is 060°W, and the star's declination is 20°N, what is the direction of the LOP relative to the AP?
