    A 2009 study [109] also suggests deleterious impacts on animals and ecosystems because of perturbation of polarized light or artificial polarization of light (even during the day, because direction of natural polarization of sun light and its reflection is a source of information for a lot of animals).

    en.wikipedia.org/wiki/Atmospheric_refraction

    Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

  4. Sunflowers do not always point to the Sun. Flowering sunflowers face a fixed direction (often east) all day long, but do not necessarily face the Sun. [123] However, in an earlier developmental stage, before the appearance of flower heads, the immature buds do track the Sun (a phenomenon called heliotropism). Mature flowers face east.

    Because rainbows are seen on the opposite side of the sky from the Sun, rainbows are more visible the closer the Sun is to the horizon. For example, if the Sun is overhead, any possible rainbow appears near an observer's feet, making it hard to see, and involves very few raindrops between the observer's eyes and the ground, making any rainbow ...

    10.12 Then spoke Joshua to the LORD in the day when the LORD delivered up the Amorites before the children of Israel; and he said in the sight of Israel: 'Sun, stand thou still upon Gibeon; and thou, Moon, in the valley of Aijalon. 10.13 And the sun stood still, and the moon stayed, until the nation had avenged themselves of their enemies.

    The distortion changes at a high rate, typically more frequently than 100 times a second. In a typical astronomical image of a star with an exposure time of seconds or even minutes, the different distortions average out as a filled disc called the "seeing disc".
