Sun path across the sky

North is up. Centre = directly overhead. Outer ring = horizon. Dotted rings = 30° and 60° altitude.

What the phases mean. Civil twilight is when there's enough light to do most outdoor activities without artificial light. Nautical twilight is when the horizon is just barely visible at sea — historically when sailors could still take star sights.Astronomical twilight is when the sky is dark enough for serious astronomy.Golden hour is photographer-speak for the period when the sun is between about 6° below and 6° above the horizon — soft, warm, directional light. The calculations use the Meeus / NOAA solar position equations (same math behind astronomy software, accurate to within a minute or two anywhere on Earth).
