233. On 22 July your 0442 DR position is LAT 26°35.6'N, LONG 22°16.7'W. You observe an unidentified star bearing 104°T at an observed altitude (Ho) of 9°55.7'. The chronometer reads 05h 39m 03s, and is 03m 14s slow. What star did you observe?
Only Rigel's declination and hour angle match the observed altitude and bearing from the given DR position when using the Nautical Almanac and sight-reduction tables.
