The area experiencing all-night civil twilight around the summer solstice lies between about 60☃3′ and the polar circles at 66☃3′ North and South. Timing of the twilight phases where you are Twilight Around the PolesĪt high latitudes and around the summer solstice, the Sun does not move lower than 18° below the horizon, so twilight can last from sunset to sunrise. In Oslo (about 60° North) and the northernmost tip of Antarctica (about 60° South), the same process takes roughly 43 minutes.In New York (about 40° North) and Wellington (about 40° South), during the equinoxes, it takes about 28 minutes from the beginning of civil twilight until the Sun rises.For example, in Quito, Ecuador, which is very close to the Equator, civil twilight begins only about 21 minutes before sunrise during the equinoxes.Īt higher latitudes, in both the Northern and Southern Hemispheres, the Sun's path makes a lower angle with the horizon, so the twilight phases last longer: In locations where the Sun is directly overhead at noon-for example at the equator during the equinoxes-the Sun traverses the horizon at an angle of 90°, making for swift transitions between night and day and relatively short twilight phases. The duration of each twilight phase depends on the latitude and the time of the year. It marks the beginning of nautical twilight.Īstronomical terms & definitions Timing and Length Similarly, civil dusk is the instant when the geometric center of the Sun is 6 degrees below the horizon in the evening. However, unlike the term twilight, which describes a time span, the terms dawn and dusk refer to moments during the transitions between day and night.Ĭivil dawn is the moment when the geometric center of the Sun is 6 degrees below the horizon in the morning. The twilight phases in the morning are often called dawn, while the twilight phases in the evening are referred to as dusk. Only the brightest stars and planets, like Venus and Jupiter, can be seen with the naked eye.ĭifferent degrees of twilight in the Civil Dawn and Civil Dusk Sunrise and sunset are the moments when the Sun's upper edge touches the horizon.Īs the Earth's atmosphere scatters and reflects much of the Sun's rays, coloring the sky bright yellow and orange, artificial lighting is generally not required in clear weather conditions to carry out most outdoor activities. In the morning, this twilight phase ends at sunrise in the evening it begins at sunset. During civil twilight, the geometric center of the Sun's disk is at most 6 degrees below the horizon. The 3 twilight phases on a world map Civil TwilightĮach twilight phase is defined by the solar elevation angle, which is the position of the Sun in relation to the horizon. Astronomers differentiate between 3 phases: Twilight is the time between day and night when the Sun is below the horizon but its rays still light up the sky. During this twilight phase, the Sun is just below the horizon.

Neither really last that long. If it is a cloudy day you may only get deep shades of blue. After a large volcano eruption you might find the sky more red orange than magenta. Furthermore it also depends on what is in the atmosphere. In other words it has to dip below the actual horizon and not just hiding behind the building in front of you. Just because you do not see the sun does not mean it is below the horizon. A sunrise and sunset is not based on visibility of the sun, but rather the position of the sun relative to the horizon. One of which is understanding what a sunset or sunrise is. The key to getting a great magic hour image is based on a few factors. Very often photographers will report that they were unable to achieve these colors. ![]() During this time the sky will turn different shades of magenta depending on how far below the horizon the sun is. On the other hand, Magic hour is the hour after the sun sets or before the sun rises. The closer the sun is to the horizon the deeper the color. During this time you will notice that the sky is a wonderful shade of yellow and orange. Hour and what is Magic Hour? Golden Hour is the hour before the sun sets or the hour after the sun rises.
