190. On 2 January your 1759 zone time DR longitude is 45°17.6' W. At that time you observe Polaris with a sextant altitude (hs) of 24°16.5'. The chronometer time of the sight is 08h 57m 10s, and the chronometer error is 02m 16s slow. The index error is 3.5' on the arc, and the height of eye is 42.5 feet. What is your latitude by Polaris?
After correcting the sextant altitude for index error, dip, and Polaris corrections using the Nautical Almanac, the latitude is calculated to be 2318.8' N.
