On 10 June your 1712 zone time DR position is LAT 25°10.0' S, LONG 06°58.0' E. You are on course 213°T at a speed of 9.0 knots. Considering their magnitude, azimuth, and altitude, which group includes the three stars best suited for a fix at star time?

Question

On 10 June your 1712 zone time DR position is LAT 25&deg;10.0' S, LONG 06&deg;58.0' E. You are on course 213&deg;T at a speed of 9.0 knots. Considering their magnitude, azimuth, and altitude, which group includes the three stars best suited for a fix at star time?

Accepted Answer

Option A: Acrux, Procyon, Arcturus. Optimal star fixes require bodies spread in azimuth, ideally 120 degrees apart, with moderate altitudes between 15° and 70°. Acrux, Procyon, and Arcturus provide the best geometric distribution and magnitude for the specified latitude and time, minimizing the potential for intercept errors in the resulting celestial fix.
