For the past few nights, observers in northern parts of Europe have spotted velvety, electric-blue tendrils rippling across the sunset sky. NLCs are a summertime phenomenon first reported by polar observers in the 19th century. In recent decades, for reasons no one fully
understands, the clouds have intensified and spread as far south as Utah and Colorado.

High-latitude sky watchers in both hemispheres should be alert for auroras.
