This article explains that an English poet named William Cole, was doing a walk at the city of Norfolk one day in October 1799. Suddenly he was observed a rare phenomenon in the  dark sky. The appearance was so extraordinary that he was photographing the sky. 

Actually this phenomenon is called moonbow, rather a lunar bow, this phenomenon is formed when the atmosphere contains vapors wet, these flowing and the pale moon exhibits its lunar arc.

A final appearance on 18 October 2016, two hundred years after it's possible to observe a phenomenon that has many people never heard and much less has been seen, that it's confirm the observation that had William Cole in October of 1799. This week the social websites have been comenting the photo which was captured on 18 October.

The lunar arc is generated in the same way that the rainbow, but in the overnight, it's happen when the light reflected from the moon instead of shining directly of the sun, is reflected through  the rain or the fog suspending in the dimming atmosphere. His fleeting projection is more delicate than the rainbow, lunar bow doesn't show the full spectrum of colors and it appears colored with a white ice.

This strange occurrence has led many artists and painters to desing canvas and squares with the image of the moonbow.

I think that this new was interesting, because explains this phenomenon that was more than two hundred years that doesn't observed and since has appeared this year it is important to remember, because, because we don't know if we can see once more.
