What color is this?

Sunset or sundown is the daily disappearance of the Sun below the horizon in the west as a result of Earth's rotation.

The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun's disk disappears below the horizon in the west. The ray path of light from the setting Sun is highly distorted near the horizon because of atmospheric refraction, making the sunset appear to occur when the Sun’s disk is already about one diameter below the horizon. Sunset is distinct from dusk, which is the moment at which darkness falls, which occurs when the Sun is approximately eighteen degrees below the horizon. The period between sunset and dusk is called twilight.

Locations north of the Arctic Circle and south of the Antarctic Circle experience no sunset or sunrise at least one day of the year, when the polar day or the polar night persist continuously for 24 hours.

Sunset creates unique atmospheric conditions such as the often intense orange and red colors of the Sun and the surrounding sky.

Elliott Bay is the body of water on which Seattle, Washington, is located. A line drawn from Alki Point in the south to West Point in the north serves to mark the generally accepted division between the bay and the open sound. Part of Washington's inland sea Puget Sound, it is home to the Port of Seattle, which, in 2002, was the 9th busiest port in the United States by TEUs of container traffic and the 46th busiest in the world.

It is unclear for whom the bay is named: candidates include Jared Elliott, ship's chaplain; George Elliott, ship's boy; and Midshipman Samuel Elliott; all of the Wilkes expedition. The last has been deemed the most likely namesake.

Elliott Bay is also home to Colman Dock, the main Seattle terminal of the state's ferry system, the largest in the country. Sailings regularly depart from Seattle to Bainbridge Island and Bremerton.

May through September, a small passenger ferry known as the King County Water Taxi runs across the bay, connecting Downtown Seattle with West Seattle (Seacrest Dock).
