On 3 February your 0547 zone time DR position is LAT 24°18.5' N, LONG 167°25.0' E. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?

Correct Answer: Option B — Regulus, Deneb, Antares

Effective star fixes require bodies with significant magnitude and a wide azimuthal spread. Regulus, Deneb, and Antares provide a balanced distribution across the horizon, ensuring that the lines of position intersect at favorable angles, reducing the potential for error in the resulting fix position.
