The sun rose this morning

Sunrise or arunika is an event when the top side of the Sun appears above the horizon in the east. Sunrise is not the same as dawn, where the sky begins to lighten, some time before the Sun appears, ending twilight (the event that the Sun's light is visible from late dusk until dawn). Because atmospheric refraction causes the Sun to still be visible while below the horizon, Sunrise and Sunset are, from one point of view, an optical illusion. The sun also appears larger on the horizon, but this is another optical illusion, similar to the lunar illusion.

The Sun's westward revolution around the Earth after leaving the horizon is caused by the Earth's eastward rotation, a counterclockwise revolution when viewed from above the North Pole. This illusion is so convincing that many cultures have mythologies and religions based on a geocentric model. The same effect can be seen with satellites near the poles.
