Auroras are fantastic; but I'm happy to be far
away from them, so trhey don't make too much
light to keep me awake! :mrgreen: :wink:

I watched the northern lights on a January night in 1983. They were yellow and green that night. Upon shutting off my snow machine and removing my helmet I was astounded to hear an accompanying whisssssshing sound as they danced across the northern sky. The display and accompanying sound was so incredible that I could not do anything but watch and listen until the cold set deeply in me. Awestruck I finally gave up, put on my helmet, stomped my boots to get circulation going harder, started my machine and went home. I haven't heard them since, but maybe I haven't been out in such perfect viewing conditions since then and I will never forget that sound or night.

It is unlikely that anybody has any special ability to hear these sounds. Electrophonic sound from meteors and from auroras is most likely caused by the induction of mechanical movement in electrical conductors near the observer. ELF radiation is typically well below 20 kHz, so many people are able to hear it once it is converted to sound. Typical conductors that are commonly present are jewelry, eyeglass frames, lawn furniture, BBQ grills, and garage doors. Low (a few tens of meters) atmospheric inversion layers can also create charge separation and possibly create electrophonic noise directly in the air.

Image Nightlights in Qeqertaq

Explanation: Light pollution is usually not a problem in Qeqertaq. In western Greenland the remote coastal village boasted a population of 114 in 2020. Lights still shine in its dark skies though. During planet Earth's recent intense geomagnetic storm, on November 6 these beautiful curtains of aurora borealis fell over the arctic realm. On the eve of the coming weeks of polar night at 70 degrees north latitude, the inspiring display of northern lights is reflected in the waters of Disko Bay. In this view from the isolated settlement a lone iceberg is illuminated by shore lights as it drifts across the icy sea.
