On 19 November your 0200 zone time DR position is LAT 18°41' N, LONG 150°37' E. You are on course 014°T at a speed of 18 knots. You observed 3 celestial bodies. Determine the latitude and longitude of your 0600 running fix.

Correct Answer: Option D — LAT 19°45.4'N, LONG 150°52.6'E

Advancing a celestial LOP over a four-hour interval at 18 knots on course 014°T accounts for the vessel's run. Projecting the initial DR through this vector establishes the correct running fix at LAT 19°45.4'N, LONG 150°52.6'E.
