Great to finally see a SAR arc (Stable Auroral Red Arc. SAR arcs occur during geomagnetic storms when the inner edge of the ring current interacts with a contracted plasmasphere.. A portion of the ring current energy is dissipated as hear that gets conducted along geomagnetic field lines into the topside ionosphere.
You couldn't see the arc by eye only on camera and again most people didn't see it as it was south of the aurora similar to seeing STEVE.
With the snow the red really stood out with a colourful aurira
