How can you tell the difference between astronomical twilight and night?
Here's the formula: From sunset until the Sun is six degrees below the horizon is civil twillight. It's still light enough to read. When the Sun is six to twelve degrees below the horizon is nautical twilight. One can still see the horizon at sea; that is, tell when the sea stops and the sky starts. From twelve to eighteen degrees is astronomical twilight, which is when the stars start to come out. After the Sun is more than eighteen degrees below the horizon, it's officially Night.
