Aurora light

1- An aurora is a natural light display in the sky. 2- Auroras are caused by charged particles, mainly electrons and protons. 3- Incident protons can also produce emissions as hydrogen atoms after gaining an electron from the atmosphere.

Glory

1- A glory is an optical phenomenon that resembles an iconic saint's halo about the shadow of the observer's head. 2- The glory can only be seen when the observer is directly between the sun and of refracting water droplets.

Corona

1- A corona is an aura of plasma that surrounds the Sun and other celestial bodies. 2- The Sun's corona extends millions of kilometers into space and is most easily seen during a total solar eclipse.

1- A light pillar is a visual phenomenon created by the reflection of light from with near horizontal parallel planar surfaces. 2- The light can come from the Sun (usually at or low to the horizon) in which case the phenomenon is called a sun pillar or solar pillar. 3- It can also come from the Moon or from terrestrial sources such as streetlights.

Mirage

1- A mirage is a naturally occurring optical phenomenon in which light rays are bent to produce a displaced image of distant objects or the sky.

Lightning

1- Lightning is a powerful sudden flow of electricity (an electrostatic discharge) accompanied by thunder that occurs during an electric storm. https://3loom.net

1- Crepuscular rays are rays of that appear to radiate from the point in the sky where the sun is located. 2- These rays, which stream through gaps in or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions.

Rainbow https://3loom.net

1- A rainbow is an optical and meteorological phenomenon that is caused by both reflection and refraction of light in water droplets resulting in a spectrum of light appearing in the sky. 2- Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Rainbows can form in mist, such as that of a waterfall Halo

1- A halo is an optical phenomenon produced by ice crystals creating colored or white arcs and spots in the sky. 2- Many are near the sun or moon but others are elsewhere and even in the opposite part of the sky. 3- They can also form around artificial lights in very cold weather when ice crystals called are floating in the nearby air.

Sun dogs https://3loom.net

1- Sun dogs are an atmospheric phenomenon that consists of a pair of bright spots on either side on the sun, often co-occurring with a luminous ring known as a 22° halo.

irisation 1- irisation, a type of photometer, is multiple mixed iridescent colors caused by sunlight being diffracted in clouds. 2- The colors are often brilliant and mingled together, sometimes similar to mother-of-pearl. 3- They sometimes appear as bands parallel to the edge of the clouds. 4- Irisation is caused by very uniform water droplets diffracting light.
