Asunto: [NavList 5414] Exercise #13 Azimuth of a planet

Exercise #13  Azimuth of a planet

On 13 June 2008, a ship is approaching anchorage.  On the gear test

check off list, there is a box stating “gyro error calculated and

posted.”  The sky is mostly overcast and the sun looks like it will be

obscured by clouds for most of the morning.  Fortunately abaft of the

starboard beam, Jupiter is shining brightly in the late morning

twilight.  The alidade was set up on the starboard gyro compass

repeater and a bearing was taken at 05h 29m 00s ZT.  (ZD -10).  The

bearing was 232.7 degrees.  The ship is in position Latitude 15deg 14’

North, Longitude 145deg 07’East.  Determine the gyro error for

arrival.
