Dawn in Dublin, stage by stage
Dawn in Dublin unfolds in three stages before the sun appears. Astronomical dawn is the first faint light, when the sun is 18 degrees below the horizon. Nautical dawn follows at 12 degrees, and civil dawn, the moment there is enough light to see and move around, arrives at 6 degrees below. This civil dawn is what most people call first light. From there the sky brightens quickly to sunrise. The whole sequence is longer at high latitudes, where the sun climbs toward the horizon at a shallow angle, and short and fast near the equator. Every time here is computed for Dublin's coordinates and shown in its local time zone.
