99. On 14 September your 1810 ZT DR position is LAT 27° 12.0' S, LONG 71° 10.0' E. You are on course 060° T at a speed of 15.0 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 1822 running fix. ZONE OBSERVED BODY TIME GHA ALTITUDE (Ho) DECLINATION ------------------- -------- ------------- ------------ --------------- Venus 1810 341° 30.4' 38° 48.9' S 12° 48.1' Altair 1816 255° 00.4' 41° 20.3' N 8° 49.3' Peacock 1822 247° 55.8' 48° 39.5' S 56° 47.8'
The running fix at 1822 is located at LAT 27 11.0' S, LONG 71 14.5' E, determined by advancing lines of position to a common time and their subsequent intersection, which is consistent with the ship's DR track and celestial observations.
