I saw the Northern Lights (aurora borealis) when I was staying north of Edmonton, Canada during the winter of 1984. At the time I was told the display before me was not classed as a particularly spectacular presentation but it totally blew me away.
The sight mesmerized me; deep three-dimensional multi colored layers of brilliant light that rapidly changed through a kaleidoscope of colours. Satiny wave upon wave of illumination across the dark horizon that danced and flickered, coiling up and then down and swirling around in ever changing patterns that shimmered across the night sky. It was one of the most oddly amazing sights I have ever seen and perhaps even stranger, was the hissing, crackling sound, that reverberated in the air around me. I was caught in a surreal moment in time – one I will never forget.
