Have you seen STEVE? Glowing in purple & green colors, a new celestial phenomenon, known as STEVE, is caused by charged particles from the Sun colliding with Earth's magnetic field.

The display was initially discovered by a group of citizen scientists who took pictures of the unusual lights and playfully named them "Steve." Scientists have since learned more about the purples and greens, and have given it a more accurate name: Strong Thermal Emission Velocity Enhancement, which can still can be shortened to STEVE.

A citizen science project called Aurorasaurus, funded by NASA and the National Science Foundation (@nsfgov), wants your help gathering photos so they can learn more about this mysterious phenomenon. Aurorasaurus tracks appearances of auroras — and now STEVE — around the world through users submitting reports and photographs directly on its mobile app and on aurorasaurus.org.
