β 13y agoIt is a concept of refraction. The sun is starting to rise and the sun's rays hit the
clouds, causing it to seem like the sun is already starting to rise. The sun sets two
minutes later the same way.
======================================
Clouds have nothing to do with refraction.
-- Shining through air causes light to bend, almost always slightly downward.
-- If the light from the setting sun curves slightly downward on its way to you,
then it appears to you as if the sun is slightly higher in the sky than it really is.
-- In the couple of minutes immediately after the sun sets below the horizon,
it still appears as if it's above the horizon.
In very extreme atmospheric conditions ... like in harsh deserts ... the curvature of
light through air can be extreme, and objects can appear to be much higher in the
sky than they really are. That's how you get the 'mirage' of an oasis in the sky,
plus legends of flying horses and magic carpets, from the Arabian desert.

west is the sunset because of the gravity of the earth! and because of its rotation
The Twilight , The sunset :)
Sunset or sunrise.
Long shadows are cast at sunset when the sun is at its lowest. The times of sunset (and sunrise) are readily available and may often be found in diaries.
This phenomenon is called atmospheric refraction. The Earth's atmosphere bends or refracts sunlight, causing it to appear above the horizon before the actual sunrise. This refraction effect is more pronounced closer to the horizon and varies depending on atmospheric conditions.
Atmospheric refraction makes the Sun appear higher than it really is.
The sunset is earlier in the fall.
because
after sunset and before sunrise
This is called refraction and it is due to the bending of the ray of light from the star as it enters the atmosphere which has a changing refractive index at different heights. This effect occurs at all heights (angles) but is more noticeable close to the horizon and it alters the time of sunrise and sunset by a few minutes.
30 minutes after sunset
due to scattering of light .........
Gemini will be best visible in the evening sky during January. It will rise in the east around sunset and reach its highest point in the sky around midnight. Look for the recognizable constellation with its two bright stars, Castor and Pollux.
