Two Suns recently appeared over China, but the phenomena apparently can't be explained by optics. Jim Kaler of the University of Illinois stated that its obviously a refraction phenomena, but how it occurred still isn't clear.
"I doubt it's been computer modeled," he said. "There must have been some blob of atmosphere somewhere that caused this truly spectacular phenomenon, which in a sense is a mirage."
Hmmm...seems these weird Sun optics happen around China a lot. Perhaps, the atmosphere is shaped differently around the Himalayas or perhaps those mountains somehow throw more ice crystals into the air?
