A classic arc of aurora borealis showing pink pillars and an upper red glow above the main arc. The Kp was 5 this night but with the Bz often north. Early in the evening the aurora appeared as a bright but mostly featureless arc and was visible even in the twilight. This shows the display just before midnight, as it brightened and danced with structure in a brief substorm outburst. A thin STEVE arc appeared shortly afterwards. This is a single 10-second untracked exposure with the TTArtisan 11mm full-frame fish-eye lens wide open at on the Canon EOS Ra camera at ISO 6400 (the lens is only for mirrorless cameras and does not transmit lens metadata to the camera).
