Direction: Strictly write this in 5 bondpaper, because my activity book have 5 spaces. This is actually for maritime industry course, but I think Geometry can do this. Use nautical almanac. Task number: A 1.1, A1.7 TOPIC/ Celestial Navigation, Compass - Magnetic and Gyro [Activity : Determine compass ervor (magnetic and gyro) using azimuth-chasing a suitable celestial body (Sun/Stars | Planets / Mon). Apply variation to Find the deviation of the magnetic compass. Minimum number of times that activity should be recorded: 9 (3 each phase) Sample calculation (Azimuth- Stars): On 05th May 2006 at 11h00m00s UTC, a vessel in position 04°30'N 010°00'W observed Canopus bearing 145° by compass. Find the compass error. If variation was 4.0° East, calculate the deviation.
