361. On 5 May in DR position LAT 38°34.5'N, LONG 124°20.7'W, you take an ex-meridian observation of the Sun's lower limb. The chronometer time of the sight is 07h 59m 10s, and the chronometer error is 01m 10s slow. The sextant altitude (hs) is 67°27.0'. The index error is 1.4' on the arc, and your height of eye is 30 feet. What is the latitude at meridian transit?
Reduce the sextant altitude to a true altitude, apply the ex-meridian latitude correction from the Nautical Almanac, and calculate the latitude at meridian transit, resulting in LAT 3836.0'N.
