Locals were outside snapping Wednesday as the sun reflected off high-flying cirrus clouds to dazzling effect.
Apparently, the phenomenon is known as a “circumhorizontal arc,” or “fire clouds.”
Echo Park Now, which pointed us to this story, explains the phenomenon this way:
[It takes] place usually when the sun is at its highest point in the sky, producing not fire nor a rainbow, but reflections from ice crystals in high cirrus clouds. This one wasn’t a full arc, but just a small, patchy fragment.
