Question

On 12 June your 0400 ZT DR position is LAT 22&deg;31.0'N, LONG 31&deg;45.0'W. You are on course 240&deg;T at a speed of 16.5 knots. What will be the zone time of sunrise at your vessel?

Accepted Answer

Option C: 0523. Sunrise is computed using the LHA of the sun at zero altitude, combined with the observer's latitude and sun's declination. Accounting for vessel motion along course 240°T from the 0400 DR results in 0523 zone time.
