Aurora Borealis Sub-storm Near the Equinox

A coronal hole high speed stream a few days ago put us on alert for some activity. I was lucky enough to catch my 1st sub-storm while driving on North Shore Drive! As I was driving, the sky practically exploded in front of me so I immediately pulled over and cut off my headlights. Not only were there bright green bands northward,  but there were disconnected rays right in front of me! They were like diamond daggers, a sort of celestial firework that is hard to explain. I can’t even really find photos that do this phenomenon justice, because perhaps the camera picks up more light than the eye, so the effect is a little swamped out by the other light. They almost looked like a group of really diffuse comets with very broad, prismatic tails and geometric nuclei pointed toward the horizon.
