“#SAID refers to a narrow flow of charged particles in Earth’s upper atmosphere. Researchers already knew that SAID existed, MacDonald said, but they did not know that it might occasionally be visible.

#STEVE is visually different from auroras, which are caused by electrically charged particles that glow when they interact with the atmosphere”
