Details:
It was a busy night on October 11 for varied aurora phenomena, as the G2 aurora storm filled the sky with Northern Lights. This was from southern Alberta, where the display of curtains early in the evening showed horizontal "dune" structures, along with isolated blobs. Later, those blobs to the south were joined by a dim red SAR arc, invisible to the eye but the camera recorded it. A time-lapse shows it moving east to west.
