Disclaimer: The Birkeland current concept associated with the electric Sun is not consistent with modern astrophysics, and it does not account for cosmic winds as a source of the currents that produce high-altitude plasma.' This particle-fluid simulation maps the spec’s phases into a single evolving auroral model. It starts with particles seeded into an annulus around the magnetic poles, then rotates that ring with magnetic tilt to create the oval footprint and asymmetry. Each frame applies a Lundquist-style split between axial and azimuthal flow, so the particles behave like twisted Birkeland flux ropes with built-in backflow. Energetic particles accelerate along the field, while emission color and brightness shift from green to red for primaries and blue-purple for return currents. Alfvén-like waves, burst factors, and local shear add pulsation, instability, and counter-rotating layers. The motion is advanced with small explicit time steps, producing stable fluid-like evolution. Overall, the app presents a magnetized plasma where current, flow, energy, and color stay coupled, creating a vivid aurora curtain rather than isolated moving dots.
