Quick Answer
Use a compass at night by orienting it to the North Star, then aligning it with your magnetic compass to account for declination, and finally using the compass to guide you in the desired direction.
Preparing for Nighttime Navigation
Before using a compass at night, make sure you have a clear view of the North Star (Polaris), which is approximately 33° above the northern horizon. If you’re south of the equator, use the Southern Cross to locate the South Celestial Pole. This reference point will help you orient your compass accurately.
Using a Magnetic Compass at Night
At night, use your magnetic compass to guide you. To account for declination, which can be up to 20° in extreme cases, subtract or add the declination value from your magnetic compass reading to get the true north direction. For example, if your declination is +15°, add 15° to your magnetic north reading to get the true north direction.
Navigation Techniques
To navigate at night using a compass, break your journey into smaller segments and use the compass to guide you in each segment. For example, if you’re trying to reach a destination 5 miles away, break the journey into 2-mile segments and use the compass to guide you in each segment. Additionally, use landmarks and features to help you stay on course, and regularly check your compass to ensure you’re on track.
