Have you ever seen a Circumhorizaon Arc?

**Themius** · 2012-12-13, 04:15 PM

I don't see them that often... which is a bummer they're so pretty.

**Belize** · 2012-12-13, 04:16 PM

Nope, never seen. That's really cool though!

**Darsithis** · 2012-12-13, 04:20 PM

I've never seen anything like that, but damn, I want to

**RICH1471** · 2012-12-13, 04:21 PM

Not seen one before, hope to one day. Where was that picture taken?

**LeyrHao** · 2012-12-13, 04:22 PM

Awesome O_o

**Howard Moon** · 2012-12-13, 04:22 PM

Circumcision arc? My goodness!

**Jess Day** · 2012-12-13, 04:23 PM

I can't even say it yet alone see one.

And no, unfortunately I haven't. Saw plenty of aurorae when I was young, though. Haven't seen good ones in a long time. Weren't quite as rainbow colored I have to say.

I last saw a rather sizable one over New York City like three years ago, and once more over some place in Delaware that was smaller. Everyone was looking at it like "What is that?"

**Deadvolcanoes** · 2012-12-13, 04:31 PM

I've never seen one but hope to some day.

I also think Moonbows are really cool. I've seen one of those.

Ooh I've never seen one of those!

Apparently they only happen at 55 degrees north when the sun is at it's highest. If I had the money I would make a giant room to simulate this... lol.

I think a circumhorizaon arc should be the person's OWN choice.

This was exactly what I expected this thread to be about xD
I was pleasantly suprised when I found out it didn't

**Liliara** · 2012-12-13, 06:50 PM

Never saw it! Looks nice though

**Haftepaff** · 2012-12-13, 07:45 PM

No i haven't, but it's kinda beautiful and wish i could've seen one.

**Lagwin** · 2012-12-13, 07:55 PM

Yes...and only about three weeks ago at that first one i've seen and the first my dad,aunt and gran had seen as well

**Majad** · 2012-12-13, 08:05 PM

Never seen one and I doubt I will. I don't think that exists in Portugal.

Get them in LA once in a while usually in spring after it has rained, they are cool because they are fluffy rainbow clouds.

they are caused by humidity in the upper-atmosphere, and the angle of sunlight. It's just clouds causing the Prism effect. they happen everywhere but usually it's off in the distance and most people don't notice clouds nearly enough.

If you had checked out the Wikipedia link a few posts below the OP, you'd have found this:
