Enough illumination renders artificial sources unnecessary for most outdoor activities. -- Nautical twilight: 6° > Solar angle > -12° -- Astronomical twilight: 12° > Solar angle > -18° +- Nautical twilight: -6° > Solar angle > -12° +- Astronomical twilight: -12° > Solar angle > -18° A very thorough explanation of this is available in the Wikipedia article about the [Twilight](https://en.wikipedia.org/wiki/Twilight).
