On 13 November your 1030 ZT DR position is LAT 19°03'S, LONG 6°34'E. You are on course 164°T, speed 12 knots. Determine your 1200 position using the following observations of the Sun. ZT GHA DECLINATION Ho 1112 351°55.4' S 18°00.4' 88°08.0' 1121 354°10.4' S 18°00.5' 88°33.9'

A LAT 19°22.3'S, LONG 6°37.8'E

B LAT 19°15.8'S, LONG 6°36.8'E

C LAT 19°17.6'S, LONG 6°39.2'E

D LAT 19°20.1'S, LONG 6°41.4'E

AI Explanation

The correct answer is A) LAT 19°22.3'S, LONG 6°37.8'E. This is determined by using the information provided, including the 1030 ZT DR position, course, speed, and the observed sun's GHA and declination at 1112 ZT and 1121 ZT. By applying celestial navigation principles, the 1200 ZT position can be calculated based on the given data. The other options are incorrect because they do not accurately reflect the 1200 ZT position based on the provided information and proper celestial navigation calculations.
