# Alberta Aurora Chasers **Domain:** Citizen Science / Heliophysics / Aurora Photography **Doc Type:** Community Node The **Alberta Aurora Chasers** are a community of aurora observers and photographers whose detailed reports helped scientists recognize that the luminous ribbon later formalized as [[Strong Thermal Emission Velocity Enhancement|STEVE]] was a distinct phenomenon worth investigating. ## STEVE Context Community administrator Chris Ratzlaff supplied the familiar name “Steve,” borrowing from _[[Over the Hedge]]_. NASA credits the group’s observations as central to the citizen-science pathway that connected ground reports with formal research. ## Routes [[articles/STEVE|STEVE]] · [[NASA]] · [[Strong Thermal Emission Velocity Enhancement]] ## Sources - [NASA — mystery of the purple lights](https://www.nasa.gov/science-research/heliophysics/mystery-of-purple-lights-in-sky-solved-with-help-from-citizen-scientists/) - [NASA citizen scientist Chris Ratzlaff](https://science.nasa.gov/people/chris-ratzlaff/)
