Astronomical Sunrise 17:13 AMAstronomical sunrise occurs when the Sun is 18° below the horizon and the sky begins to brighten from a completly darkened state.
Nautical Sunrise 17:45 AMNautical sunrise (or nautical dawn) is the precise moment when the sun's center is 12° below the horizon in the morning. It marks the beginning of nautical twilight, allowing pilots/mariners to see the horizon.
Civil Sunrise 18:17 AMCivil sunrise is the moment in the morning when the sun's center is 6° below the horizon. It marks the start of morning civil twilight, providing enough natural light for most, outdoor activities without artificial lighting. It typically occurs roughly 20-30 minutes before actual sunrise.
Sunrise 18:43 AMSunrise (or sunup) is the moment when the upper rim of the Sun appears on the horizon in the morning. It marks the end of the twilight phase, often accompanied by distinct atmospheric colors.
