What is morning twilight called?
Quick Answer: Morning twilight is called dawn. It’s the period just before sunrise when the sky starts to brighten but the sun is still below the horizon.
Morning twilight, or dawn, happens because the sun’s light begins to scatter in the atmosphere while it is still below the horizon. This gentle glow signals the start of a new day and helps wildlife and people prepare for daylight.
Dawn is divided into phases like astronomical, nautical, and civil twilight depending on how far the sun is below the horizon. Each phase brings a different level of light, with dawn marking the very first light before the sun rises.
