26. On 22 May your 0437 ZT DR position is LAT 25°18.5' N, LONG 51°18.0' W. You observe an unidentified star bearing 097°T at an observed altitude (Ho) of 48°20.0'. The chronometer reads 07h 40m 40s and is 03m 24s fast. What star did you observe?
Only Markab's computed altitude and azimuth, derived from the DR position, GMT, and Nautical Almanac data, match the observed altitude and bearing. Therefore, the unidentified star is Markab.
