On 23 March your 1600 ZT DR position is LAT 27°16.3' N, LONG 156°48.2' W. You are on course 063°T at a speed of 18.0 knots. Considering their magnitude, azimuth, and altitude, which group includes the three stars best suited for a fix at star time?

Correct Answer: Option C — Hamal, Rigel, Alphard

Effective celestial fixes require stars spaced approximately 120° apart in azimuth. Hamal, Rigel, and Alphard provide the best geometric intersection at this specific DR position. Bowditch guidelines emphasize selecting bright stars (low magnitude) at moderate altitudes to minimize atmospheric refraction and ensure clear identification during the twilight window.
