On 7 March at 1838 ZT, in DR position LAT 34°26.9' N, LONG 58°16.2' W, you observe Polaris for latitude. The sextant altitude (hs) is 35°08.4'. The index error is 2.5' off the arc. The height of eye is 54 feet. What is the latitude at the time of the sight?

Question

On 7 March at 1838 ZT, in DR position LAT 34&deg;26.9' N, LONG 58&deg;16.2' W, you observe Polaris for latitude. The sextant altitude (hs) is 35&deg;08.4'. The index error is 2.5' off the arc. The height of eye is 54 feet. What is the latitude at the time of the sight?

Accepted Answer

Option B: 34&deg;33.4'N. For a Polaris sight, correct the sextant altitude for index error, dip, and refraction to find Ho. Apply the Polaris correction tables (a0, a1, a2) based on the LHA Aries at the time of the sight. The resulting latitude is 34°33.4'N, consistent with standard celestial navigation protocols.
