On 28 February your 1850 zone time DR position is LAT 27&deg;49.0'N, LONG 159&deg;24.0'W. Considering their magnitude, azimuth, and altitude, which group includes the three stars best suited for a fix at star time?

Accepted Answer

Option B: Rigel, Schedar, Regulus. Rigel, Schedar, and Regulus provide the necessary azimuthal spread and brightness for a reliable evening fix at this latitude. Bowditch emphasizes selecting stars that are well-distributed around the horizon to minimize the impact of any single observation error on the final fix position.
