At 1000 ZT 21 October your DR position is LAT 29°00'N, LONG 134°40'E. Determine the computed altitude (Hc) of the Sun for the assumed position nearest to the above given latitude and longitude, given a chronometer time of 01h 00m 00s.

Question

At 1000 ZT 21 October your DR position is LAT 29&deg;00'N, LONG 134&deg;40'E. Determine the computed altitude (Hc) of the Sun for the assumed position nearest to the above given latitude and longitude, given a chronometer time of 01h 00m 00s.

Accepted Answer

Option D: Hc 42&deg;35.7'. Applying standard Bowditch sight reduction methods, establish the assumed position nearest the DR coordinates, determine GMT, extract ephemeris data for the Sun, and solve the navigational triangle to find the exact computed altitude (Hc).
