What causes an aurora?

Bottom line: When charged particles from the sun strike atoms in Earth’s atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.

Do Northern Lights happen every night?

When is Northern Lights season? There is no official season since the Northern Lights are almost always present, day and night. Caused by charged particles from the sun hitting atoms in Earth’s atmosphere and releasing photons, it’s a process that happens constantly.

How often does an aurora Borealis occur?

“Active periods are typically about 30 minutes long, and occur every two hours, if the activity is high. The aurora is a sporadic phenomenon, occurring randomly for short periods or perhaps not at all.”
