The other night, the sky above my port was the color of a dead television tuned to any station. Namely, ghostly blue and flickery, from auroras. I rarely and barely see them this far south, and I'm too close to bright lights to see any color in them. But that makes them interestingly near-subliminal. If they weren't moving, I'd barely be able to see them. I'm amazed the cats outside didn't stare up at them, given their vast interest in anything that flickers and shimmers.
