An arc of normal green aurora across the north, but with a fainter but redder arc to the south above it at the start of a display this night. Another very dim but mostly red arc lies far to the north. The red arc at top looks somewhat like a STEVE arc but appeared before the aurora got brighter. Taken from the Churchill Northern Studies Centre, in Churchill, Manitoba, on February 28, 2022. This is looking north during a low-level Kp2 display.

This is a single 20-second exposure with the TTArtisan 11mm lens at f/2.8 and Canon R6 at ISO 3200.
