Useful Clarification of Sunset, Sunrise and Twilight

A sunrise:  This is when the top of the sun appears on a sea-level horizon.

A sunset (Sundown):  Occurs when the top of the sun just disappears below the sea-level horizon.

Dusk: The sun has set, the sky is darkening, but there is still some blue in the heavens.

Twilight:  A time of day when there is light in the sky, but the sun is not yet visible.  Thus it could refer to the time just before sunrise, or just after sunset.  Furthermore, there are three 'grades' twilight.

Civil Twilight: The sun is no more than 6 degrees below the horizon at either sunrise or sunset.  You can still see the horizon, yet should be able to make out the brightest stars, especially if there is no moonlight.  One still should be able to carry on ordinary outdoor activities.

Nautical Twilight:  Now the sun is between 6 and 12 degrees below the horizon at either sunrise or sunset.  You cannot make out the horizon.  You need extra light for ordinary outdoor activities.

Astronomical Twilight:  This is dark; the sun is between 12 and 18 degrees below the horizon at either sunrise or sunset.  Under ideal conditions you should detect faint sky illumination, a sense that dawn is near.

Picture of Sunset At the North Pole

Sunset at the pole

This is a sunset at the North Pole.  What is also interesting is the moon, which looks so huge.  The photograph was taken on May 11, 2009 at a time when the moon appears nearest to the sun at this extreme latitude.

Sunset Timing

The time of sunrise and sunset varies with day of the year, latitude, and longitude. The published sunrise and sunset times are calculated without regard to surrounding terrain. That is, all computations are made for a sea-level horizon, even in mountainous areas. Thus the actual time of sunrise at a particular location may vary considerably from the 'official' times.

The Rayleigh Effect

The red hues seen in the sky at both sunset and sunrise are caused by the Rayleigh* effect.  This is caused by the scattering of blue light.  Whereas there is relatively little scattering of red light consequently the sky takes on shades of red, orange and yellow.

I expect that you have noticed how sunset is more brightly coloured than the sunrise.   This is because all the hours of daylight results in more dust in the lower atmosphere at evening than at dawn.

*The blue colour of the sky is caused by the scattering of sunlight off the molecules of the atmosphere. This scattering, called Rayleigh scattering, is more effective at short wavelengths [the blue end of the visible spectrum]. Therefore the light scattered down to the earth at a large angle with respect to the direction of the sun's light is predominantly in the blue end of the spectrum.

Some of the most spectacular sunsets occur after volcanic eruptions such as Mount Pinatubo in 1991 and Krakatoa* in 1883.  Moreover, this is not just a local effect, volcanoes cause spectacular sunsets and sunrises all over the world. Sometimes just before sunrise or after sunset a green flash can be seen.
