What atmospheric phenomenon has been reported by amateurs and then by NASA in 2015?

Answer

Steve, Strong Thermal Emission Velocity Enhancement by retroacronymy, is a luminous phenomenon reported from 2015 onwards. It takes the form of a thin bright purple ribbon associated with green, adopting an east-west alignment. Its appearance is thus reminiscent of a polar aurora, although it is observed below the auroral zone.
