Fire Rainbow?

Today, April Fool's Day, I got an email asking me if I've "ever seen a fire rainbow". This is supposedly the "rarest of all naturally occurring atmospheric phenomena".

Is there such a thing? Google "fire rainbow" for urban legends info. Only Snopes mentions it, and says it's true, but I can't find any scientific reference to it.

You might find this thread interesting:
Submit Pictures to APOD, Circumhorizontal Arc (Fire Rainbow)

What the heck is "Snopes"?

Thanx, FieryIce, for the link.
"Snopes" is short for http://snopes.com -- a pop-up-packed urban legends website.

Also look it up on the EPOD site (Earth Picture Of the Day)

I'll try and find the one that was sent to us a few years ago when they first started to appear around the earth. Yes, they are a NEW anomolie.

I have seen the rainbow too at my school recently,

But surely i think it is from water,

When the day rains n suddenly it becomes hot n shiny,there would be rainbow,but,how to explain a circle rainbow,like the one in the picture?

When the sun shines through a sheet of floating ice particles in the high atmosphere, thE crystals act as tiny prisms and refract the light. Much as a rainbow is only visible at a certain arc and opposite the sun (52deg?), the circular form is also bent in an arc but the anomoly occurs around the sun (or moon) like sundogs. The degree of arc is determined by the angle of refraction and your point of view

O.O..

So,from the ice prisms,when the light shines through it,it will show all the seven colours of a rainbow n forms a circular rainbow from different angles of the ice prism?

thx for ur explanation..! :D

You could try to do some research for yourself, , ,

Try here for some more about such things.

Hmm,i think its one of the greenhouse effect,it causes the atmosphere of our earth changes suddenly..
