Question 1431Navigation General
70% to passYour vessel is at the equator at midnight on 1 January, and a star is observed rising. At what time will this same star rise on 1 February, assuming your vessel's location is still at the equator?
A
2208
B
2110
C
2158
D
2317
AI Explanation
The correct answer is C) 2158. The reason is that the rising time of a star at the equator depends solely on the star's celestial coordinates, which do not change significantly over the course of a month. Therefore, if a star is observed rising at midnight on January 1st at the equator, it will rise approximately 28 minutes earlier on February 1st, also at the equator. The other options are incorrect because they do not accurately reflect the 28-minute earlier rise time of the star between January 1st and February 1st at the equator.
