Timelapse video sequences and photography were captured on April 14, 2013 in northern Minnesota by Mark Ellis (markellis.com).
The music is from Bruce Cockburn's "Deep Lake" (brucecockburn.com).
Transitioning from snow storms in the day and overcast skies in the evening, the clouds cleared for several hours in the very early hours of April 14, 2013 revealing the stars and aurora. The darkness of the sky was enhanced by an essentially moonless night. Moving bands of fog crisscrossed the snow covered lake. The air temperature was 20°F (-7°C) and the camera and lens required careful protection from frost buildup. The unprotected tripod became fully covered with thick ice crystals by the end of the image collection process.
This mild aurora display resulted from a solar flare that occurred on April 11, 2013:
Increasing aurora activity through 2013 is likely as we approach the next peak in the sun's normal 11-year activity cycle. The solar maximum is expected in late 2013.
