248. On 22 May your 0437 DR position is LAT 25° 18.5' N, LONG 51° 18.0' W. You observe an unidentified star bearing 142° T at an observed altitude (Ho) of 23° 10.2'. The chronometer reads 07h 40m 40s, and is 03m 24s fast. What star did you observe?
Fomalhaut's computed altitude and azimuth, based on the DR position and corrected GMT, closely match the observed altitude and bearing, making it the correct identification.
