On 29 July your 1930 zone time DR position is LONG 164°26.0' E. At that time you observe Polaris with a sextant altitude (hs) of 23°46.8'. The chronometer time of the sight is 08h 32m 18s, and the chronometer error is 02m 26s fast. The index error is 2.7' on the arc, and the height of eye is 56.0 feet. What is your latitude by Polaris?

Question

Accepted Answer

Option A: 24°19.5'N. Determining latitude from Polaris involves correcting sextant altitude for index error, dip, and refraction to find true altitude (Ho), then applying almanac-derived corrections (a0, a1, a2) based on the Local Hour Angle of Aries to obtain LAT 24°19.5'N.
