Aurora Borealis: 10-11 October 2024

/ Add comment

The Sun remains active as it approaches Solar Max and the possibilities of observing the aurora at lower latitudes remains good. Earlier this month there was a Severe Geomagnetic Storm (G4 with Kp8) that produced visible auroras in northern Arizona. Some of the pillars of light were easy to see–others required longer exposures on the camera.

We watched and photographed the event from Ashurst Lake near Flagstaff, Arizona. I was hoping to capture reflections of the aurora on the still waters of the lake and was successful.

Here are a few images…

The first pillars of the aurora appear even before twilight has ended.

An ultra-wide angle lens was not wide enough so I switched to a fish-eye lens.
