Natural Phenomenon

Hi guys!
Today I wanna tell you about natural phenomenon.
Let me explain the definition about that. A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition and so on.
This is fire rainbow-the rarest of all naturally occurung atmosphere phenomena.

(this picture was captured in washington border. The event lasted about one hour. Clouds have to be cirrus, at least 20K feet in the air.)

 With just the right amount of ice crystals and the sun has to hit the clouds at prciesly 58 degrees.
I have seacrched in the internet, and I like fire rainbows for the most.
Is that rainbow that we usually see on a house or building? Okay, this is the Fire Rainbows.
“Fire Rainbows” are neither fire, nor rainbows, but are so called because of their brilliant pastel colors and flame like appearance.
During the summer, if you're very lucky, you may notice a cloud in the sky that looks just like a rainbow. These so-called “fire rainbows” are actually known as circumhorizontal arcs and can occur when the sun has risen higher than 58° in the sky. For those living at mid-latitudes, the best chance to see this phenomenon is in the middle of summer. The rarity of the event is highly dependent upon latitude and weather conditions. The potential for these arcs to form in Los Angeles is 5-10 times higher than in London.

I hope I have an occassion to see this with the most people that I love. Oke, see you!!
