I had never seen anything like this; at least not until a few months ago. We were driving back to Portland,OR from the Tillamook area, when I spotted this fascinating natural phenomenon in the eastern sky.

I would have called this colourful thing in the sky ‘a rainbow of some sort’ if I hadn’t come across a picture on GMA in the week that followed. A question was posed to the viewers as to what that was, and I soon had a name for this vibrant sight I had seen only a few days prior to that.
Circumhorizontal Arc.
Quite a colourful piece of information, that. πŸ™‚

Ever seen a double rainbow; a full one at that?

      It is. For a moment, I wasn't sure I was really seeing those colours. πŸ˜€
      Splendid indeed.

      Thank you Arti. πŸ™‚

    New to me.
    I hope to spot something like this soon. The skies are cloudy enough.

      I was in complete awe.
      Never expected to see something like that. I guess I was at the right place at the right time, although, I only got to take those pics from a moving car.

      Happy weekend, Niranjan. And hey, Onashamsagal!

    That is a rainbow for sure, trying to imitate Aurora Borealis!

      Definitely there was 'splitting of light' there, but it wasn't much of a bow, USP. It was just spread over a larger area and wasn't as well-defined as a rainbow generally is. And it wasn't moving like the Aurora Borealis.
      To me it looked like clouds that had turned colourful. When I tried doing some homework on it, I came across terms: 'rainbow clouds,' and 'fire rainbows; and those sounded like a good names for this colourful thing.
      I hear this happens when ice crystal play prism (as opposed to water droplets as in the case of rainbows).

      Twice this year? Lucky you! πŸ™‚
      I'm guessing it's not exactly a rare thing in the Norwegian skies.
      Thank you, Mormor. You have a nice day too.

    Without getting into the science, logics and reasons I'd say it's awesome!

      It sure is, Amit.
      I wish I had better pics; these were from a moving car. I'm not sure I'd get to see a similar sight again.

    I'll probably not remember the term, but I'll know at least there is one for this wonderful phenomena. I saw this every so often many years ago when I used to commute over the San Mateo-Hayward Bridge.

      You did? Wow! I never got to see one in California, so I thought it was only seen further up north.
      Thank you Su-sieee πŸ™‚
