Celestial Navigation · Hour Angle — LHA East Longitude
GHA is 340°00' and your assumed longitude is 50°00' E. What is the LHA (0°–360°)?
- A050°00'
- B290°00'
- C390°00'
- D030°00'✓ Correct
Explanation
In east longitude, LHA = GHA + east longitude = 340° + 50° = 390°. Subtract 360° to keep the result within 0°–360°: 390° − 360° = 030°.
