Aurora watchers were on alert! Look up after sunset on June 22 and the sky should be alive with dancing lights.
And the predictions were right.
I headed out to a nearby lake in preparation for seeing and shooting the show. And as soon as the sky got dark enough the Lights were there, despite the bright solstice twilight.
The display reached up to the zenith, as seen in my fish-eye images, like the one below. I shot with three cameras, all shooting time-lapses, with the fish-eye camera recording the scene suitable for projection in a digital planetarium.
However, it was apparent we here in western Canada were seeing the end of the display that had been going on for hours during an intense geomagnetic storm. The aurora was most intense early in the evening, with a minor outburst about 11:30 to 11:45 pm MDT.
The aurora then subsided in structure and turned into a more chaotic pulsating display, typical of the end of a sub-storm.
However, an attraction of this display was its juxtaposition over another storm, an earthly one, flashing lightning to the northwest of me.
By 1 a.m. MDT the display, while still widespread over a large area of the northern sky, had turned into a diffuse glow.
But 60 gigabytes of images later, I headed home. The time-lapse compilation will come later!
