Auroral Arcs, Loops and Swirls (Feb 5, 2019) #5 of 5
Auroral Arcs, Loops & Swirls (Feb 5, 2019) #5.jpg
One of a short series of images showing the development of an aurora display from a classic arc into a more complex pattern of concentric arcs and with loops and swirls. This was Feb 5, 2019 from the Churchill Northern Studies Centre. The outburst lasted only 5 minutes or so and might have been due to the Bz interplanetary field turning south briefly. After this series, the display faded and fractured into faint arcs and a diffuse glow across the sky.
This is a single exposure with the 12mm Rokinon full-frame fish-eye and Nikon D750.
