Aurora over Scotland (1 file)

Aurora Borealis or Northern Lights displays photographed taken over Aberdeeshire in Scotland since 1989 covering some 350 events with arc, rays, coronas with a wide rnage of shapes and colours
Aurora Corona Forming aucf13105jhp Aurora Borealis Scottish coronal glow south green red Deeside Aberdeenshire photos taken on the evening of the 30th at Crooktree, 25 miles west of Aberdeen looking from the east to the south. This digital photo was taken at 23.01.36hrsUT for 17secs, showing green and red oxygen background glow a precursor of another corona strength display looking southwards which was an indication of the strength of the display. The cf131 digital sequence, starting at 22.58.22, shows the continuing activity following on from the very active night of the 29th/30th with another Corona to be viewed through until the last frame at 23.25 which was frustrated by complete cloud cover and rain. Photos were taken with both digital and slide film and the first slide film started at around 21.50hrsUT on the evening of the 30th when the extensive cloud cover cleared. The magnetometer on site showed vigorous activity from 21.30hrs. This digital photo was taken with a Fujifilm Finepix Digital S2Pro camera, at maximum ISO of 1600 using a Sigma 15mm f2.8 fisheye lens, giving a fairly undistorted wide angle image, wide open aperture with most exposures manually near the 20 seconds mark which experience suggested was around the best exposure for the low light Aurora displays. These were some of my first digital recordings taken during 2003 when the quality of digital cameras had at last matched 35mm slide film standards and the noise factor was superior to the grain created pushing 400asa slide film to 1600asa.
