Sunrise morning

Sunrise is the moment when the upper limb of the sun appears on the eastern horizon in the morning. The term transcends the horizon to refer to the entire process of the solar disk, as well as its atmospheric effects.

Sunrise

Although the sun has been seen to rise from the horizon, it is actually the motion of the earth that causes the sun to appear.
Earth observers have the magic of the moving sun in a rotating reference frame; This apparent motion is so convincing that in many cultures myths and religions have been built around geographic models, which were prevalent until the astronomer Nicholas Copernicus created his heliocentric model in the sixteenth century.

Architect Buckminster Fuller proposed the terms sunset and sun clip to better represent the heliocentric model, although the terms did not enter into common parlance.
From an astronomical point of view, the sunrise occurs only instantly: the moment the upper limb of the sun appears sensitive to the horizon.
However, the term sunrise usually refers to the period before and after this point:

Twilight, in the morning the sky is illuminated at that time, but the sun is not yet visible. The beginning of the twilight of the morning is called the dawn of astronomy.

Attractive color and atmospheric effects are still seen after sunrise.
