Your 0745 ZT 15 July position is LAT 29°04.0'N, LONG 71°17.5'W. You are on course 165°T, and your speed is 8.0 knots. You observed 3 morning sun lines. Determine the latitude and longitude of your 1130 running fix?

Correct Answer: Option C — LAT 28°35.0'N, LONG 71°08.5'W

Advancing three morning sun lines along the course and speed vector up to the 1130 fix time establishes the running fix coordinates. The intersection accounts for run distance and azimuth spread to achieve precise celestial positioning.
