118. On 14 January your 1922 DR position is LAT 27° 18.5' S, LONG 67° 18.0' E. You observe an unidentified star bearing 295° T at an observed altitude (Ho) of 13° 50.7'. The chronometer reads 03h 25m 43s, and is 03m 15s fast. What star did you observe?
The correct star is Markab because its computed altitude and azimuth, derived from the chronometer-corrected GMT and DR position, match the observed altitude and bearing.
