'FIRE RAINBOW'π₯π This photo of what seem to be rainbow-colored flames in the sky are making rounds on social media. This phenomenon was seen and captured in August 2021 near North Fork Mountain in West Virginia, USA. NASA clarified that this optical phenomenon occurs when ice crystals in a distant cirrus cloud act like little floating prisms. This circumhorizontal arc is informally known as a fire rainbow for its flame-like appearance. π· Chris Harbig, Christa Harbig, NASA #Photography
