    Colourful moon dog observed, or what??

    Look at the following picture, taken 12/9 by Thomas Sannes:
    http://www.storm.no/nyheter/fotograferte-sjeldent-vaerfenomen-3583707.html

    He sent the picture to meteorologists, and they made their bet that this rainbow-coloured bright spot on the night sky was some sort of moon dog, although these tend to be uniform white.

    Any other suggestions from PF'ers?

    Probably a moon dog. Per wiki on moondogs: Moondogs show little color to the unaided eye because their light is not bright enough to activate the cone cells of humans' eyes.

    However a camera is much better at capturing color than the human eye in low light.

    The observer has affirmed that he DID see colours with the unaided eye (that was what brught his attention to it in the first place), but that the camera sharpened the colours somewhat.

    So it was a very rare moon dog from what I understand. I wish I had seen it myself.
