On 22 June your 0424 ZT DR position is LAT 26°18.5' N, LONG 124°18.2' W. You observe an unidentified star bearing 031°T at an observed altitude (Ho) of 49°26.0'. The chronometer reads 00h 23m 24s and is 01m 32s slow. What star did you observe?

Correct Answer: Option C — Schedar

Convert chronometer time to GMT. Extract GHA Aries and SHA from the Nautical Almanac to determine the star's LHA and Declination. Comparing these values against the star list for 22 June confirms Schedar, as its celestial coordinates match the observed altitude and bearing at the DR position.
