NOTES : Sun is slightly horizontally compressed due to atmospheric inversion. In meteorology, an inversion is a deviation from the normal change of an atmospheric property with altitude. It almost always refers to a temperature inversion, i.e. an increase in temperature with height, or to the layer (inversion layer) within which such an increase occurs. This image piece was created by sunlight refracting through an atmospheric inversion layer on Earth where cold air was trapped near the surface. These effects arise when the Earth's atmosphere acts like a prism, sending different colours of light on slightly different paths.


Never point your camera, optical devises on to sun unless you know what you are doing and safest point of sun.
