76. On 22 March your 1834 DR position is LAT 26°13.5'S, LONG 108°36.5'W. You observe an unidentified star bearing 062°T at an observed altitude (Ho) of 23°22.0'. The chronometer reads 01h 32m 37s, and is 01m 50s slow. Which star did you observe?
Regulus is the correct identification because its predicted altitude and bearing, calculated using the corrected GMT, DR position, and LHA Aries, closely match the observed values.
