 Normally, when the Kp index hits 2 or 3, only Finland and Canada get to see some auroral action in their skies, and we seen nothing due to our more southerly location. However, on this night the ionized airglow to the north was greatly enhanced, glowing green and with some linear structure! At the same time, they were shooting nice aurora in Norway and Alaska, I was taking a deep exposure with the fish eye lens to the north on a very transparent completely cloudless night. While its not rays and curtains of aurora, it is basically the same phenomenon.
