On 16 July your 1920 ZT DR position is LAT 25°36.0' N, LONG 172°18.9' W. Considering their magnitude, azimuth, and altitude, which group includes the three bodies best suited for a fix at star time?

Correct Answer: Option D — Venus, Antares, Vega

For a reliable celestial fix, select bodies with a wide azimuth spread and altitudes between 15° and 70°. Venus, Antares, and Vega provide the most balanced geometric distribution for the specified date and latitude, ensuring the lines of position intersect at favorable angles for an accurate vessel position.
