On 1 October you determine the zone time of evening twilight will be 1835. Your DR position will be LAT 27°18.0' N, LONG 48°52.0' W. Considering their magnitude and location, which group of three stars are best suited to be used in obtaining a fix at star time?
AI Explanation
The correct answer is C) Alphecca, Kochab, Deneb.
To determine the best group of three stars for obtaining a fix at the given time and location, we need to consider the stars' magnitude and position relative to the observer's location.
The stars Alphecca, Kochab, and Deneb are well-suited because they are all bright stars (magnitude 2 or less) and are located in the northern part of the sky, which is the best region for obtaining a fix at the given latitude (27°18.0' N) and during evening twilight. The other answer choices, while containing bright stars, are not as well-positioned for this specific scenario.
