All-Sky Red Aurora, Northern Alaska, above the Arctic Circle #5319

An unusual all-sky red aurora above the Arctic Circle, northern Alaska. The temperature was around 5 degrees F and even though there were no coronal mass ejections from the Sun, and only low level geomagnetic activity predicted, the night was filled with all-sky colorful aurora. The aurora colors are red from oxygen emission above about 150 km altitude and pink/purple from nitrogen emission. The yellow is from oxygen emission at 557.7 nanometers (yellow-green) at about 100-150 km altitude plus the red oxygen emission behind the green, making yellow. Visually, the pinks and reds were pastel pink and red.

The view is to the north with Cygnus behind the trees on the right and Cassiopeia at the upper left, with the Milky Way extending from Cygnus to Cassiopeia. The foreground is the view outside a cabin in Wiseman, Alaska.

Technical. The image was obtained with a Canon EOS R5 Mirrorless Digital Camera and a Sigma 24mm f/1.4 DG HSM Art Lens (B&H).
with a single 13-second exposure at ISO 1600, f/1.8. The image was corrected for perspective distortion of the wide-angle lens. White balance is daylight. This is the full image, no crop.
