Rare Fire Rainbows: It looks like a rainbow on fire but these circumhorizontal arcs aren’t rainbows. They are caused by light passing through high-altitude cirrus clouds. The sun has to hit the clouds at precisely 58 degrees and have just enough crystals in order to form in the sky.
Chicago-based Stacee Kalmanovsky’s Rain installation is perfectly placed below a skylight, showing the beauty of glass droplets that really look like rain. Looking up at it in person is an experiment in vision and perception.
