South Pole, dead of winter, no sun for months. So, that rules out a rainbow in the above image. Instead it’s an aurora, but it was doing its best, with its graceful arch, to imitate a rainbow. Not so much for some of the other auroras last week. The one at the bottom bears little resemblance to a rainbow—mostly green in color and creating a large squiggly design in the sky (sometimes, with a little imagination, the shapes they create are suggestive of other things). Besides the auroras, it was a rather quiet week at the Pole, with a few brief power outages and a July 4th celebration with karaoke and a scavenger hunt.
