163. On 17 March your 1845 DR position is LAT 25°10.0'N, LONG 66°48.0'W. You observe an unidentified star bearing 340°T at an observed altitude (Ho) of 66°25.1'. The chronometer reads 10h 47m 49s, and is 1m 54s fast. What star did you observe?
Capella's computed altitude and azimuth, derived from the DR position and corrected time using the Nautical Almanac and sight reduction tables, match the observed altitude and bearing, confirming its identification.
