Though unseen by the naked eye, the aurora-like scenes streaking across the Milky Way were captured by photographers.

“At first I thought maybe a thin cloud but not the case,” Christopher Hoffman, who photographed the scene in St. Mary’s County, Md., said in an email. “After research I came across a article that said spaceX launch Falcon 9 was launched at 12:27 a.m.”that also linked the glow to the SpaceX rocket.

About the same time that Johnston and Hoffman photographed the glow, David Cortner of Rutherford College, N.C., captured what he described as “rocket-powered aurora,” according to SpaceWeather.com.He said the red blob was related to the engine burn of the Falcon 9′s second stage, which typically starts about three minutes after liftoff and lasts about six minutes. The second-stage burning usually occurs from 68 to 310 miles high, where positive oxygen ions are present in the atmosphere.
