There's just something about a rainbow that worthy of taking a picture, especially when the colors are so bright. The set-up Thursday night was perfect for great rainbows across many areas of KELOLAND.
Pictures were taken by viewers in places including Viborg, Harrisburg, Brandon, Sioux Falls and Arlington. In order to get such nice pictures, the weather conditions really have to be just right. The best rainbows like those seen Thursday night happen most often in the early morning or late evening when the sun's position in the sky is lower.
Most of us have a general understanding on how they work, but here's a little refresher course. Assuming there is direct sunlight either directly behind or in front of a shower, odds are good your see a rainbow. The rays from the sun reflect off of the billions of rain drops in the departing clouds. Once the light bounces off the raindrops, the light refracts or bends, allowing the light rays to separate based on their color.
Many of the rainbows Thursday night featured a double rainbow. This is more complicated, requiring the light to reflect a second time from inside the raindrops. If you look carefully, you'll notice the colors of the second rainbow are inverted or opposite the first as red moves to the inside and blue to the outer part of the rainbow.
No pots of gold on these pictures, but the sights are pretty and a nice part of our scenery as we close out the summer season this weekend.
Thanks to everyone who sent us photos of the rainbow. Check out our photo gallery below.
