The Northern Lights dance through the night, ending with a finale burst of blue.
Here’s the time-lapse movie, below, that I shot Friday, May 17, beginning at 11:30 pm and ending 4 hours later at 3:30 am. The sky was bright with moonlight when I started the sequence, with the aurora especially active over half the sky. The display settled down to form a slowly pulsing green band behind the old barn, which went into silhouette after the Moon set.
Then, just as the sky was brightening with the first glow of dawn, the aurora kicked up its heels again and danced across the north, shooting beams of blue across the sky.
I ended the sequence as dawn was fading in … and I was fading out! Still, it was a wonderful night to be out under the stars.
The movie compresses 4 hours of aurora shooting into 40 seconds of aurora playback!
I assembled the time-lapse movie from 1200 frames, each 11-second exposures at 1 second intervals, with the Canon 60Da at ISO 1600 and 10-22mm lens at f/4.
