"Normally heard either during the night at middle-upper latitudes or at sunrise in middle (as in the Alvord Desert Dawn Chorus recording), this was recorded IN THE MIDDDLE OF THE DAY 40 miles northeast of Fairbanks, Alaska, right within the Auroral Zone. It went on continuously for 3 days! Had it not been daylight, the Auroral Borealis would have been dancing in the skies right overhead! Weird squawks, chirps, hiss, and occasional very low groans can be heard. Recorded in central Alaska on 06 September 1995 between 1945-2200 UT.

Stephen P. McGreevy has documented recordings he made of Natural Radio - electromagnetic emissions in the very-low-frequency band caused by massive discharges and their after-effects in lightning storms and by the solar wind buffeting the earth's magnetic field, visible as Aurora Borealis and Australis. It would normally take long wires to pick up these emissions, which would hamper the mobility of a listener or recordist. McGreevy developed a portable receiver with a whip antenna, allowing him to travel to places with optimal recording conditions - that is, anywhere in tempera… read more
