On 16 March your 0330 ZT DR position is LAT 22°36.0'S, LONG 76°16.0'E. You are on course 098°T at a speed of 16 knots. What will be the ZT of sunrise at your vessel?

Correct Answer: Option C — 0553

Determine the LMT of sunrise from the Nautical Almanac for the vessel's latitude. Convert LMT to ZT by applying the longitude correction (1 hour per 15 degrees). Adjust for the vessel's change in longitude during the transit to the sunrise position to find the precise ZT of 0553.
