Question 32Navigation Problems70% to pass
On 22 May your 0437 DR position is LAT 25°18.5'N, LONG 51°18.0'W. You observed an unidentified star bearing 233°T at an observed altitude (Ho) of 29°42.3'. The chronometer reads 07h 40m 40s, and is 03m 24s fast. What star did you observe?
AI Explanation
The correct answer is B) Sabik.
To determine the star observed, we need to use the information provided - the position, observed star bearing, and altitude, as well as the chronometer reading and error. By plugging these values into star identification tables or calculators, we can determine the most likely star that was observed.
Given the position, bearing, and altitude, the star that best matches these criteria is Sabik. The other answer choices (Hamal, Diphda, Markab) do not align as closely with the provided information.
