Celestial Navigation · Meridian Altitude — Latitude
At LAN the sun's Ho is 55°00', it bears due south, and its declination is N10°00'. What is your latitude?
- AN45°00'✓ Correct
- BN35°00'
- CS45°00'
- DN65°00'
Explanation
Zenith distance = 90° − 55° = 35°, toward the north (sun bears south). Latitude = ZD + declination (signs N+) = 35° + N10° = N45°.
