*Dawn and dusk (twilight) periods are time spans before sunrise or after sunset, respectively:
- Civil twilight is the time before sunrise and after sunset when the sun is at a maximum angle of 6 degrees under the horizon. Usually it is possible to read the paper under these twilight conditions. First stars become visible (up to magnitude 1).
- Nautical twilight is the time before/after the civil twilight when the sun is at a maximum angle of 12 degrees under the horizon. The most important stars are visible (magnitude 3) as well as the horizon. Therefore, nautical positioning using classical instruments is possible.
- Astronomical twilight is the time before/after nautical twilight when the sun is at a maximum angle of 18 degrees under the horizon. Horizon is not visible anymore, all stars become visible. After/before that twilight all stars are visible.
