    Electromagnetic storms on the sun during early fall of 2024 offered multiple opportunities for Pennsylvania residents to witness rare aurora borealis events. The colors seen are dependent on the energy of the electrons as they collide with atmospheric gasses. Green light is emitted by high-energy electrons while low-energy electrons produce red light.
