On 2 February your 0400 zone time DR position is LAT 24°14.0' N, LONG 163°28.0' W. You are on course 322°T at a speed of 22 knots. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?
Official USCG Answer & Rule Citation
Correct Answer: Option C — Saturn, Antares, Rasalhague
For a reliable star fix, select bodies with a wide azimuth spread and moderate altitudes. Saturn, Antares, and Rasalhague provide the optimal geometric configuration at the specified time and latitude, ensuring the lines of position intersect at angles near 90° to minimize the impact of potential observation errors.
