Question 102Navigation Problems70% to pass
On 20 June your 1742 zone time DR position is LAT 24°55.0' S, LONG 8°19.6' E. Considering their magnitude, azimuth, and altitude, which three stars are best suited for a fix at star time?
AI Explanation
The correct answer is B) Regulus, Canopus, Antares.
Explanation:
1) The correct answer is B. This is because Regulus, Canopus, and Antares are bright, prominent stars that are well-suited for celestial navigation fixes at the given latitude and longitude.
2) The criteria for selecting the best stars for a fix include the stars' magnitude (brightness), azimuth (direction), and altitude (height above the horizon). Regulus, Canopus, and Antares meet these criteria - they are bright, visible in the southern hemisphere at the given coordinates, and will be at a good altitude for taking sights.
3) The other options are less suitable - Spica, Arcturus, and Alioth are more northern stars, while Avior, Sabik, and Fomalhaut may not be as prominent or favorably positioned for a fix at that location.
