Etymology

(2016) Backformation from the nickname "Steve" given to this aurora-like light. Acronym of strong thermal emission velocity enhancement. The nickname "Steve" resulted from a meeting between citizen scientists and researchers from the University of Calgary at a bar, to discuss the purple light. 'Steve' is the namesake of a cartoon character from the 2006 animated film "Over the Hedge", where cartoon animals try to peek over a suburban hedge. The backronym resulted from researchers creating a meaning to the nickname "Steve", keeping the original nickname for the formal name.^{[1][2][3][4][5][6]}

Noun

STEVE (uncountable)

1. An aurora-like light found in southern Canada (consistently lower latitude, unlike the aurora borealis which is generally high latitude), composed of a glowing purple ribbon of light, with green spikes coming off obliquely parallel to each other, moving at about 6.5 km/s East to West. Presumably occurs in the southern hemisphere as well.

     Although STEVE has been documented by amateur night sky watchers for decades, it is an exciting new upper atmospheric phenomenon for the scientific community.

     Respecting its nickname, they have dubbed the phenomenon STEVE, an acronym for Strong Thermal Emission Velocity Enhancement.
