Caption: | Aurora Borealis Scottish spring display rays colours blue red pinkDeeside Aberdeenshire taken on the evening of 27th March, 2017 at Crooktree, 25 miles west of Aberdeen, starting around 21.43UT and was indicated by the magnetometer readings on AuroraWatch. Although cloud was forecast earlier the display happened before the cloud arrived but when it got dark enough to see it. A low grade Arc was visible to the North, beneath Cassiopeia at 21.44, it went active shortly afterwards with faint multiple rays with bright bases on the arc and some lateral movement, North to West and it died down again very quickly at 21.47UT, allowing approximately 10 exposures. Colours not visible to the human eye to the brightness this photo records. Magnetometer suggested possible further activity but by 22.00 there was 100% cloud cover. This photograph was taken with a Nikon D700 full frame DSLR using a 28mm Nikkor f2.8 lens at f4 aperture, ISO3200 for 7.4 seconds at 21.45.30hrsUT. The increased ISO sensitivity of modern DSLR’s allows for shorter exposures circa 10 sec average times giving more accurate recordings of these moving events. |
