If you've ever seen the real thing, time-lapse aurora video just doesn't do it. It has been necessary until fairly recently with the advent of inexpensive cameras with good low light performance. From a few nights...
The sounds Wright recorded may be a result of “electrophonic transduction”–that is, the conversion of electromagnetic energy into mechanical motion. At the time of the Christmas aurora outburst, magnetic fields around Abisko were seething with activity. Physics 101: Unsettled magnetic fields can cause currents to flow in power lines. Strong low-frequency currents can literally shake objects, launching acoustic vibrations into the air. Wright may have recorded the unique sound of those power lines swaying in response to the magnetic storm.
I grew up watching more than a few auroral displays. Although often stunning, most of the video these days is time lapse while the real thing unfolds in a much more stately fashion. Improvements in video cameras are providing the sensitivity necessary for real time work Here's a recent example.
About this time of year I field questions about which telescope to buy for a budding amateur astronomer. My advice is to stay away from telescopes at first and concentrate on learning the sky. There are amazing sights that can be enjoyed with a pair of binoculars at relatively low power. Ten to fifteen power is great, but you'll want big lenses ... 50 millimeters or more if possible. You can spend a lot on serious instruments - thousands in fact, but for beginners something like this Celestron 15 power with 70 millimeter objectives is ideal and inexpensive. You can also use them for birdwatching.
