314. On 28 May your 0200 DR position is LAT 19°16.5' S, LONG 119°24.0' W. You are on course 107°T at a speed of 18 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix. Body Zone Time GHA Observed Declination Altitude Diphda 0524 076°20.5' 50°34.8' S 18°05.4' Antares 0530 201°26.0' 14°16.9' S 26°23.4' Deneb 0538 140°18.4' 22°00.3' N 45°12.6'
The 0600 running fix is determined by reducing each celestial sight, advancing the resulting lines of position (LOPs) along the ship's track to 0600, and finding their intersection, which is LAT 1943.0'S, LONG 11754.0'W.
