PIX4671797: Colored crown around the Sun - Corona around the Sun - Crown or dark circles are light phenomena produced by the diffraction of light by droplets in the clouds. In meteorology, a corona is produced by the diffraction of light from the Sun by small water droplets in a cloud / Bridgeman Images
PIX4671508: Solar column - Solar pillar - Sunset and solar column. A solar column is created by the reflection of solar light on the horizontal faces of ice crystals. A solar pillar is created by the reflection of a sunlight (when sun is at or low to the horizon) on the horizontal face of ice crystals / Bridgeman Images
PIX4670911: Halo around the Sun - Sun Halo - Halos are due to the light of the Sun reflected by high-altitude clouds, cirrostratus, composed of ice crystals. They bend the light and cause a perfect circle around the Sun. Halos are caused by sunlight being refracted by cirro - stratus clouds. These are thin clouds, very high in the atmosphere, and are composed of ice crystals. They bend light at a 22 degree angle, which creates a halo around the sun that is 44 degrees in diameter / Bridgeman Images
PIX4670970: Halo around the Sun and condensation train - Sun Halo and contrail. - Halos are due to the light of the Sun reflected by high-altitude clouds, cirrostratus, composed of ice crystals. They bend the light and cause a perfect circle around the Sun. An insect is invited in the photo. 14 May 2006, Quimper Halos are caused by sunlight being refracted by cirro - stratus clouds. These are thin clouds, very high in the atmosphere, and are composed of ice crystals. They bend light at a 22 degree angle, which creates a halo around the sun that is 44 degrees in diameter. An insect is also visible. May 14, 2006 / Bridgeman Images
PIX4671000: Halo around the Sun - Sun Halo - Halos are due to the light of the Sun reflected by high-altitude clouds, cirrostratus, composed of ice crystals. They bend the light and cause a perfect circle around the Sun. To the top left of the halo, a halo circumscribed. 26 April 2008, Finistere. Halos are caused by sunlight being refracted by cirro - stratus clouds. These are thin clouds, very high in the atmosphere, and are composed of ice crystals. They bend light at a 22 degree angle, which creates a halo around the sun that is 44 degrees in diameter. A circumscribed halo is also visible towards top left. April 26, 2008 / Bridgeman Images
PIX4671117: Rainbow - Rainbow - Rainbow - Arc - en - ciel observed in Brittany on 2 May 2005. 23 minutes before the sun sets, a contrasting rainbow appears in the east. It is very high (the lower the Sun, the higher the bow). Note at the level of the “feet” of the rainbow the difference in luminosite between the interior of the rainbow (under the main arch) and the band between the main arch and the secondary arch (lower and higher). This dark band is called Alexander's Band. It should also be noted that blue is almost absent from the rainbow, because the Sun is setting, therefore orange, betrays a blue light faults that can be seen at the level of the rainbow. May 2, 2005. 23 minutes before the sunset, a contrasted rainbow appear toward the East. It's a tall rainbow, because the Sun is low. Notice the difference of luminosity at the “” feet”” of the rainbow between the inside of the rainbow (under the main arc) and the band located between the main and secondary arcs (fainter and higher). This darker band is called the Alexander's dark band. Notice too that the blue tints are missing in the rainbow, because the sun is setting, so is orange, which means that its blue tints are absent / Bridgeman Images
