Mystery in the Sky: What is the Rainbow-Shaped Cloud?

Click For Summary
SUMMARY

The discussion centers around the phenomenon of a rainbow-shaped cloud observed in Arizona, identified as a "sun dog," a type of atmospheric optical phenomenon. Participants noted that the sun dog appeared more vibrant and larger on consecutive days. The conversation also touched on the visibility of such phenomena through polarized sunglasses and included references to other atmospheric occurrences like sun columns and halos around the moon. The discussion highlights the fascination with these natural occurrences and the desire for further exploration of similar phenomena.

PREREQUISITES
  • Understanding of atmospheric optics
  • Familiarity with the concept of sun dogs
  • Knowledge of how polarized sunglasses affect visibility
  • Basic photography skills for capturing atmospheric phenomena
NEXT STEPS
  • Research the science behind sun dogs and their formation
  • Explore the effects of polarized sunglasses on visual perception
  • Learn about other atmospheric phenomena such as halos and sun columns
  • Investigate techniques for photographing atmospheric events effectively
USEFUL FOR

Anyone interested in meteorology, photographers capturing natural phenomena, and enthusiasts of atmospheric optics will benefit from this discussion.

What IS this?

Yesterday I was driving home from school when I saw that in the clouds there was what seemed to look like a portion of a rainbow :confused: :confused:

I thought it was weird, so I took a picture of it while driving, with my cell phone, so it's not the best quality :redface:

Anyway, today I was driving home from school, and again, in the same exact location, it was there again! What is this?

I'm in Arizona and this was almost exactly to the West.

this is just the rainbow looking thing, click on the picture to see the full pic

Also, today it appeared to be slightly larger with more vibrant colors.

:confused:

I saw that prism effect when I was driving home today! Are you sure you don't live in Knoxville?

Edit: Have you ever noticed that you can see it better with polarized sunglasses?

Um... it wasn't the best decision either.

I was at a red light.

You did all that in 3 seconds?

One button takes a picture. I pointed the cell phone in the general direction, pressed the button. Plus, the light just turned red as I was pulling up to the intersection, so I had more than 3 seconds anyway.

EDIT: Notice how in the full pic, the sun dog is not in the center at all.

Moose, that is so cool! I missed my once in a lifetime opportunity to photograph a sun column. :cry: A dozen cameras, and none had working batteries.

Evo, I just searched what a sun column is... That is awesome, I hope that I'll get to see one someday! Sucks about the batteries though :mad:

lol, I looked today, and there was no sun dog out to greet me :frown:

This column was incredible, I have yet to find a picture that comes close to what I saw. It was a solid hot pink column and it was almost a full inch wide (from my perspective).

You were extremely lucky to see that sundog. I envy you.

I did see another phenomena years ago. It was a circle around the moon that started as a halo just around the full moon, but as we watched, it started moving out, away from the moon, but remained a perfect circle, just growing larger and larger. It was a thin band that kept expanding out. We watched until it reached the edges of the viewable sky. I have yet to see a description of this exactly, but have found reference to a somewhat similar phenomenom caused by ice crystals in the air. It was reported on the news, but they had no explanation of it. Tons of people were calling in asking what it was. It was so many years ago, I don't believe there is any film of it. :frown:

It was a glitch in the energy shield bubble covering the Earth by the aliens! :-p

I hope that I will see cool effects in my lifetime! Maybe we should have a thread on what weird things people have seen in the sky.
