135. On 15 October your 0300 zone time DR position is LAT 27° 14' S, LONG 99° 46' E. You are on course 128° T at a speed of 19 knots. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?
Choice C (Achernar, Procyon, Aldebaran) provides the optimal combination of brightness, altitude, and azimuth separation for a celestial fix given the specified date, time, and DR position.
