A rare red aurora seen from latitude +32º N from southeast Arizona during the major Kp8-level storm of October 10, 2024. This is looking north from the Quailway Cottage near Portal, Arizona and Rodeo, New Mexico not far from the Mexican border. This demonstrates how during a large storm the red tops of auroral curtains can be seen from latitudes quite far south.

The reds were visible to the unaided eye — this was not just a photographic aurora. The camera did pick up some greens close to the horizon.

The waxing quarter Moon provided the illumination.

This is a single 15-second exposure with the RF15-35mm lens at 15mm and f/2.8 on the Canon R5 at ISO 1600. Taken as part of a time-lapse sequence. It is one of 3 images I published taken close together in time, showing slight changes in the structure.
