On 30 June at 0630 zone time, morning stars were observed, and the vessel's position was determined to be LAT 25°15.0'S, LONG 175°36.0'E. Your vessel is steaming at 16.0 knots on a course of 302°T. A sextant observation of the Sun's lower limb is made at 1015 zone time. The chronometer reads 10h 14m 38s, and the sextant altitude is 32°07.9'. The index error is 4.5' on the arc, and the chronometer error is 01m 25s slow. Your height of eye on the bridge is 58.0 feet. What is the azimuth (Zn) of this sight using the assumed position?

Question

Accepted Answer

Option A: 035.3°T. Calculate GMT by applying chronometer error to the observed time. Extract GHA and Declination from the Nautical Almanac. Using the assumed position, determine the LHA. Applying Pub. 229 for the vessel's latitude and LHA results in an azimuth of 035.3°T, adhering to standard celestial navigation reduction techniques.
