A new study reveals a dawn-side counterpart to the atmospheric phenomenon Steve, discovered through collaboration between scientists and citizen photographers.

• Steve's twin was identified using data from ESA's Swarm satellites and images from a Norwegian research station.
• The purple ribbon of light, similar to Steve, appears after midnight and flows eastward.
• This discovery underscores the importance of citizen science in advancing our understanding of atmospheric phenomena.
• The phenomenon was first spotted in 2021 and confirmed by recent satellite measurements.
• Researchers emphasize the potential for more discoveries as solar activity increases.
