On 20 June your 1742 zone time DR position is LAT 24°55.0' S, LONG 8°19.6' E. Considering their magnitude, azimuth, and altitude, which three stars are best suited for a fix at star time?

Correct Answer: Option B — Regulus, Canopus, Antares

Optimal star selection for a fix requires bodies distributed across the horizon to maximize geometric strength. Regulus, Canopus, and Antares provide the best combination of magnitude, altitude, and azimuth separation for the given latitude and time, ensuring a reliable and accurate position fix per Bowditch principles.
