circumhorizontal arc

This is rather an interesting event that happen a few months ago in subang jaya/shah alam. From my point of view its a dark cloud that has a rainbow in it, and its the 1st time i saw this kind of cloud . I want to know more about this kinda cloud but i have no idea what to google.When i first saw this, i was like What in the world is this?  so i decided to just leave it as a memory. How often do you see a circumhorizontal arc? In my 22 close to 23 years in Subang jaya that was the first time. 

what is so creative about this? its a wonderful scene with all the spectrum color in it.I was thinking could the colors around the cloud be rainbows? then it hit me! yes! maybe its raining on top of the cloud. How weird that can be huh? i just wish that i could know more about this , and i wish i could be up there when that happen again. i wonder when will be the next time i could see this kinda event again. the circumhorizontal arc.

This inspire me to become a better artist. well im not really an artist now but hopefully i would be. all the art fundamental starts with the color wheel and spectrum colors . and this think i can see it with my own eyes. its like rainbow can be form anywhere at any time. this is one of the best example of it!
