Details:
It took a while for this aurora to kick in! After skies cleared for me in southern Alberta, the aurora began to appear after midnight on June 7-8 as a diffuse arc across the north, promising to burst into activity. By about 2 a.m. MDT it started to outburst, brightening with structured rays reaching up to the zenith covering the entire northern sky. To the eye, only dim greens were visible. But the camera picked up the purples high at the tops of the curtains, perhaps from blue scattered sunlight mixing with the usual red fringes at the tops of the curtains? At this time of year sunlight is passing over the pole and lighting up the high atmosphere all night long, thus the many passes of the Space Station we are seeing every night this week. This was never a really bright or spectacular aurora but it was certainly a photogenic one. Knowing a storm was in progress I drove a few miles to an old barn, long abandoned but still working well as a foreground for nightscapes. I shot hundreds of frames this night for time-lapse movies, as well as stills.
