An extremely vigorous and fascinating mixture of what is called "chorus" or "auroral chorus" and are natural VLF radio signals emanating from within Earth's huge magnetosphere. Similar radio sounds - at AUDIO frequencies but as radio waves -- occur on planets Jupiter and Saturn also. Nature, Magnetosphere
Mesmerizing cacophony of natural VLF radio signals (vigorous auroral chorus) at audio-frequencies emanating from deep within Earth's magnetosphere as recorded on a field-recording expedition to northern Alberta, Canada in August 2000. Recorded in STEREO using two orthogonal loop antennae. Nature, Magnetosphere
Eerie "ghostly-tones" sounds of the radio emanations from Earth's huge Magnetosphere. These beautiful signals are called "natural radio" at ELF-VLF radio (AUDIO) frequencies, and are endlessly changing in variety from hour to hour at the hot spots to hear these spectacular auroral-signals. Nature, Magnetosphere
During a bright display of the Northern Lights over Vancouver Island in February 1994, I was stuck in a blizzard at a snowed-in rest stop by the Eve's River and captured this dense occurrence of "Auroral Chorus" emanating from Earth's Magnetosphere. Nature, Magnetosphere
A short recording of spectacular "wavering tones" recorded in northern Alberta, Canada on 02 June 1996. These are recordings of Earth's "natural radio" signals emanating from the Magnetosphere at audio-frequency radio signals. One of my finer recordings. High quality for AudioSparx! Nature, Magnetosphere
The bizarre sounds of "wavering tones" recorded up in the Boreal Forest region of northern Alberta, Canada in June 1996. This is a field-recording Earth's amazing and beautiful "natural VLF radio" signals that occur at AUDIO frequencies and are ever-changing. Similar process to the Auroral Borealis. Nature, Magnetosphere
Very rare low-pitched "risers" which are called that way because they rise in pitch. These are "natural VLF radio" signals coming from Earth's Magnetosphere and were recorded in central Manitoba, Canada along with the aurora. Nature, Magnetosphere
Vigorous lightning storms spark crackling sounds of electromagnetic energy while the auroral-sounds of "the dawn chorus" resembling a flock of birds accompanies the lightning static. These are the sounds of "Natural VLF radio" phenomena of Earth's Magnetosphere. Nature, Magnetosphere
This is an amazing collage of Earth's "natural VLF radio" sounds from the Magnetosphere recorded in Canada's Boreal Forest region where the Aurora Borealis shimmers overhead! This file is awesome demonsration of the signals the Northern Lights create and are perfect for a doc. about Aurora! Nature, Magnetosphere
