The Northern Lights

After reports of a KP6 geomagnetic storm predicted to strike Scotland over the weekend, and clear skies on Sunday evening, I headed out after sunset to try and catch the northern lights.  This was a very early aurora excursion as nights have only just got dark enough for decent views of the night sky, let alone tracking down the faint and elusive northern lights.

My initial outing took my into the hills above Bunchrew where I bagged some lovely views of the summer Milky Way overhead.  Turning my attention north I noticed a faint arc of light on the horizon,  and sure enough some test shots picked up a vibrant band of purple and green auroral light.  However little structure was evident until I moved to lower elevations, reaching the Bunchrew shoreline just after 10.30pm.

From this new vantage, in the dark looking over the Beauly Firth,  the northern lights stood out much more clearly as distant columns of white light, slowly morphing and scintillating above the horizon.  Some of the images (attached) show nice structure and the suggestion of wave like movement.

As our nights get darker many more opportunities to view the aurora will present themselves.  The best strategy is to simply get out there as often as you can when it’s clear, and try and escape the boundaries of light polluted towns and cities.  Aurora forecasts should only be used as a guide as they’re seldom reliable.  Remember to look north and where possible find some nice low horizons in this direction.

Good luck and clear skies.

The aurora is caused by the solar wind slamming into the earth’s atmosphere near the poles, ionising chemical elements which produce light at very specific quantised frequencies.
