Today we take a look at an image of an incredible spiral cloud formation with a description that the photo was taken in the Himalayas in 2009.
The image is a digital creation.
First, let’s take a look at the description and the photo being circulated:
Cloud spiral in the sky. An Iridescent (Rainbow) Cloud in Himalaya. The phenomenon was observed early am 18 Oct 2009.
This image was created by an artist known on Deviant Art as repawnd, and originally posted here in 2010 under the name “The Ruins” and is described as a “weather generator” in this fantasy photo. In the comments, the artist describes in detail how he achieved certain effects.
It should also be noted that the description hardly matches the photo. There is no rainbow or iridescent effect to the clouds in the fantasy image.
The description above was apparently lifted from the real photo on the right, snapped by Oleg Bartunov, which is no less breathtaking. This photo includes the following description:
The phenomenon was observed early morning on October 18, 2009 on the path to Khumjung in the Himalayas. The mountain pictured is Thamserku (6623m).
Iridescent clouds are a diffraction phenomenon cause by small water droplets or small ice crystals individually scattering light. Larger ice crystals produce halos, which are a refraction phenomena rather than iridescence. Iridescence should similarly be distinguished from the refraction in larger raindrops that makes a rainbow. If parts of clouds have small droplets or crystals of similar size, their cumulative effect is seen as colors. The cloud must be optically thin, so that most rays encounter only a single droplet. Iridescence is therefore mostly seen at cloud edges or in semi-transparent clouds, and newly forming clouds produce the brightest and most colorful iridescence.
Norwegian spiral anomaly of 2009
The spiral appearance of clouds in the fantasy image have led some to inaccurately claim that this was the Norwegian spiral anomaly of 2009. That event did not resemble the photo above, and was the result of a failed Russian missile test.
Both images are beautiful, though only one of them is real. One must wonder why people feel compelled to pass off works of art as real images to awe others.
