On 14 January your 1922 ZT DR position is LAT 27°18.5' S, LONG 67°18.0' E. You observe an unidentified star bearing 029°T, at an observed altitude (Ho) of 29°35.0'. The chronometer reads 03h 25m 43s and is 03m 15s fast. What star did you observe?

Correct Answer: Option D — Elnath

Determine Greenwich Mean Time (GMT) by applying the chronometer error to the reading. Use the Nautical Almanac to find the GHA and Declination of the Sun and stars. Calculate the Local Hour Angle (LHA) and compare the observed altitude and azimuth to star tables, identifying Elnath through celestial coordinate matching.
