Solstice Aurora Spectacular

A great northern lights show on June 22 was triggered by an intense solar storm.


SkyNews associate editor Alan Dyer captured this view of the June 22, 2015 auroral display.

An unusually intense burst of solar activity triggered an impressive auroral display that extended south beyond the U.S. border. One indicator of a geomagnetic storm’s intensity is the K-index, which runs from 0 to 9, with 9 being the most intense. Normally for aurora to be visible in southern Canada, the K-index needs to be 5 to 7. On Monday night, the K-index peaked at 8. (You can visit our Aurora Watch page to check on the current level of auroral activity.)

Photographing the sky from southern Alberta, SkyNews associate editor Alan Dyer recorded a series of images to make the video seen here. “I shot 2200 frames over about 2 hours for this sequence. I started about 11:15 p.m. MDT in the bright twilight and ended about 1:15 a.m., by which time the display had faded to a widespread but diffuse glow,” Alan reports.

Alan Dyer also recorded this all-sky view of the June 22 event with a fish-eye lens.

    That evening was a great show! I call it a full sky Aurora. Some of my best images were shot directly south…
