Purple STEVE Is Not An Aurora — It’s “New Upper Atmospheric Phenomenon”

—  “As you can imagine, I was totally stoked. This was my first STEVE sighting and it was unforgettable. It was visible with the naked eye and I could see the pulsations of green with the purple.” – Greg Ash photographed STEVE over Ely, Minnesota at latitude +47.9 N on May 5-6, 2018

Space Weather News, August 21, 2018: "For decades, amateur astronomers in Canada have been photographing a purple ribbon of light dancing alongside auroras during some geomagnetic storms. Nicknamed "STEVE", the ribbon belatedly caught the attention of the scientific community in 2016. They thought it might be a form of aurora. However, new research published August 20, 2018, in the Geophysical Research Letters suggests that STEVE is not an aurora at all, but rather something new and mysterious."
