Can someone please explain how rainbow phenomena was seen in China prior to the quake and also Augusta, Maine USA and possible other locations all on the same day May 12, and around the same time period? I have pics.

It’s the HAARP. Good luck to the Chinese.

I’ve actually seen clouds exactly like that here in New Brunswick, Canada earlier this year.

Looked like those Rocketship popsicles with the pink, white and blue layers. Spectacular, but didn’t portend anything unusual as far as weather or geological events.

Oops! I should have checked the link in Phil’s original post. The “fire cloud” link is to the blog entry I linked above.

I also should have made it clear I was trying to say that I think “refraction” is the cause of most of the phenomena discussed here, not “diffraction”. Diffraction causes effects called “coronas” and some other atmospheric optical effects but refraction/reflection in hexagonal ice crystals is responsible for sun dogs and halos and the circumhorizontal arc. Rainbows are caused by refraction/reflection in spherical drops. There are also interference effects apparently observed in atmospheric optical effects such as iridescent clouds.

I think the clouds observed in China were, in fact, a circumhorizon arc.

Phil: were you saying this too?

I showed a sundog pair to a friend of mine. She thought it was the coolest thing ever. I pointed out a full rainbow. She thought that was cool too. I showed her a sun halo. Yes, it was cool, too.

I look up to the sky plenty of times. But I see nature there, as it is.

Ever notice the rainbow’s mirror image? How about the fainter sundogs?

Heck, I’ve even see green clouds. Green clouds! And I’m from central California.
