Dark skies have returned to the North of Scotland. This welcome auroral display started off as a green arc, quite close to the horizon, with a purple haze above it. Once it became active there were some nice, bright rays. At 00:34 UT, approx., a second, fainter, green arc formed above the main one. This was short-lived. This image was taken with a Canon EOS 40D and Sigma EX 24-60mm lens; 30 Second exposures @ f/3.2, ISO-800.
