An FFGL source that's the night sky, and an effect that adds the aurora to your clip as light. The arc is a vortex sheet of electric charge that rolls itself up into curls, folds and surges, the electrons it speeds up light each spectral line at the height a real atmosphere puts it, and a camera on the ground looks up through the lot. There isn't a noise function anywhere in it.
This demo runs the plugin's shaders in your browser, so it needs JavaScript and WebGL2. The plugin itself, its source and its downloads are on its repository.
