The civil twilight is the brightest phase most people refer to this type when talking about twilight.
What can I photograph during twilight? Civil twilight
This app shows exact times for civil, nautical, astronomical twilight, calculates the time and duration of gold and blue hours, contains detailed information about the Milky Way visibility, and more. Among our apps, you’ll also find a convenient photo planner for outdoor photographers - Ephemeris. They will be especially useful for photographers in terms of planning and visualizing images. There are several tools like Photopills, Sun Surveyor, the Photographer's Ephemeris when it comes to apps. For example, Time and Date provides detailed information about sunrise and sunset for your location.
But how to figure out the astronomical twilight time? Use a website or an app. The twilight duration differs in different locations, so there is no universal time for it. Here is how low beneath the horizon the Sun’s center during each phase is: Together with twilight, there are three types of dusk and dawn. For example, when the Sun is exactly 18° below the horizon - it’s called astronomical dusk (or dawn), but the interval from 12 to 18° is astronomical twilight. Dusk and Dawnĭusk and dawn occur when the Sun’s center is at the exact point below the horizon the twilight occurs between these points. The shortest twilight is observed at the equator, where darkness falls 24 minutes after sunset the longest one can last about six weeks at the poles.
The twilight duration depends on the latitude, time of year, and weather conditions. The time after astronomical twilight when the Sun goes 18° or farther down below the horizon is called the night. They follow each other and occur in the same order all over the Earth the twilight types vary depending on the Sun’s center position below the horizon: There are three types of twilight - civil, nautical, and astronomical. We can see twilight because the Earth has an atmosphere, where the light partially scatters and illuminates our planet even when the Sun is gone. Twilight is a time of the day when the Sun is below the horizon and not visible directly but partially illuminates the sky. When is twilight? What types of twilight are there? What are “magic hours”?
