STEVE appears in a blood red arc of light in New Zealand footage

On March 17, 2015, an arc of blood-red light streaked across the sky hundreds of miles above New Zealand. Over the next half hour, an amateur skywatcher watched this arc as it transformed before his eyes into one of Earth’s most puzzling atmospheric mysteries – the strange ribbon of light known as STEVE’s name – reveal newly released images.

STEVE, short for “Strong Thermal Velocity Enhancer”, is an atmospheric oddity first described in 2018, after amateur aurora hunters saw a narrow arcing stream of wispy purple light in the sky above. over northern Canada. Scientists who studied the phenomenon quickly confirmed that STEVE was not a dawn – the multicolored glow that appears at high latitudes when solar particles collide with atoms of high Earth atmosphere. On the contrary, STEVE was a distinct and unique phenomenon that is “completely unknown“to science.
