#DidYouKnow: Sometimes mistaken for #Aurora, #STEVE ("Strong Thermal Emission Velocity Enhancement") is an atmospheric optical phenomenon that appears as a purple and green light ribbon in the sky, named in late 2016 by aurora watchers from Alberta, Canada.

The #Phenomenon is not rare, but had not been investigated and described scientifically prior to that time.
