On 22 May your 0437 ZT DR position is LAT 25°18.5' N, LONG 51°18.0' W. You observe an unidentified star bearing 097°T at an observed altitude (Ho) of 48°20.0'. The chronometer reads 07h 40m 40s and is 03m 24s fast. What star did you observe?
AI Explanation
The correct answer is B) Markab.
To determine the observed star, we need to use the information provided (the observer's position, the observed altitude and bearing of the star, and the chronometer time) to identify the star based on its position in the sky.
By calculating the star's altitude and azimuth using the observer's position and the chronometer time, we can match these values to the known coordinates of the stars, and Markab is the star that best fits the given observations.
The other options (Hamal, Sabik, and Diphda) do not have the correct coordinates to match the provided information, and therefore cannot be the star that was observed.
