PIX4671379: Arc de fog - Fogbow - Arc de fog observed in Brittany on 5 May 2006. A haze arc is formed in the way of a rainbow. The light of the Sun is reflected in the water drops of the mist, but unlike raindrops, the mist droplets are much smaller: about a millimetre for the rain versus a few centiemes for the mist. As a result, the diffraction in the mist droplets is preponderant, which results in colour refracting at random angles, between 30 and 45* around the anti-sun point (opposite the Sun). Thus, all colours blend and one sees a white arch of light, sometimes slightly bluish on the inside and red on the outside, wider than a rainbow. Fogbow seen in Brittany on May 5, 2006. A fogbow is forming like a rainbow. The sunlight reflects in the fog droplets, but thoses droplets are much more smaller than the raindrops: about hundredths millimeters for the fog instead of about one millimeter for the rain. Thus, the diffraction in the fog droplets is leading, then the colors are refracted under angles between 30 and 45* around the antisolar point (at the opposite of the Sun). Then the colors mixe and one can see a white light bow, with sometime blue in the interior and red in the exterior, larger than a rainbo / Bridgeman Images

PIX4671501: Solar column - Solar pillar - A solar column is created by the reflection of solar light on the horizontal faces of ice crystals. Therefore, a fairly stable atmosphere is needed to keep these crystals parallel on the horizon. 6 February 2006. A solar pillar is created by the reflection a sunlight (when sun is at or low to the horizon) on the horizontal face of ice cristals. So, a quiet atmosphere is needed in order that this cristals stay parallel to the horizon. February 6, 2006, Brittany / Bridgeman Images

PIX4671609: Iridescent clouds - Iridescent clouds - When parts of a cloud are very thin and contain water droplets of the same size, the diffraction of the solar light that passes through them can cause colour comparable to those of crowns.
