Rainbow Clouds over Arizona and California reported March 26, 2018.
Daniel Wood saw the same display from 38,000 feet. “I fly for a major US airline,” says Wood. “We were approaching San Diego just after sunset and I noticed some thin wispy clouds ahead over the ocean that appeared to be much higher than us. As the sun set, they began to get very colorful and iridescent–all the colors of the rainbow, but diffused over a large area.”
Part of The Event or something else, maybe.
