  • Even though I was disappointed with how quickly this storm fell apart, it went out with an interesting rainbow. The extra colors at the bottom are called supernumeraries, and they only form when water droplets are nearly all the same size. This was only the second time I've seen a supernumerary rainbow.
    Rare Supernumerary Rainbow
  • I chased a few thunderstorms that rolled off of the mountains in the afternoon. It was good rainbow weather, but they can't form in the middle of the day. Since the radius of a rainbow is always 42° and the center is directly opposite the sun (antisolar point), the sun must be at an altitude less than 42°. Around 5PM, the sun sank to 32° and this low rainbow appeared about 10° above the horizon. I stopped at this wetland and was able to cover my camera from the rain and capture a time lapse clip that I've tried many times to get. The extra colors (green, purple, green) at the bottom of the bow are called supernumeraries. It's a rare effect that happens when the raindrops are a specific diameter and mostly uniform in size. This complex light interference can't be explained by geometric optics. In fact, supernumerary rainbows played a part in the early 1800's in confirming that light is a wave, and not just made up of particles as previously thought.
    Supernumerary Rainbow
  • This double rainbow appeared in a receding rain shower near Parkman. It later became a supernumerary rainbow. But I'm not sure what it's called when all the colors seem to blend together in the middle.
