GUIDE TO ALASKAN NATURALLY-OCCURRING VLF RECEPTION WAVE FILES

IN THIS AK_VLF1.ZIP FILE:



All files recorded by Stephen P. McGreevy using a handheld WR-3E

VLF receiver and 33 to 50 inch whip antenna into a Marantz PMD-212

mono cassette recorder.



All of these files are recorded in 8-bit/11kHz sampling rate for 

greatest compatibility (but lower quality) with all sounds cards

as well as the Microsoft "speaker.drv" PC speaker sound driver.



1)	KENAIWHI.WAV	I call these "Kenai Crazy Whistlers," though they

	fall into the "periodic emission" category.  These were recorded 

	on 09 Sept. 1995 near Skilak Lake on the Kenai Peninsula about

	40 miles south of Anchorage, AK at 0930 UTC.  Very pure whistling

	tones which fall and then abruptly rise.  Seen on a spectrogram,

	they look like "hooks," hence they are also named this term.

	This location was about 3 miles from nearest A.C. power-lines.

	(61 seconds)



2)	KENAIWH2.WAV	This recording 	begins about where the recording

	in the "KENAIWHI.WAV" file ends.  (60 sec.)



3)	AKAUCHO.WAV	Recorded midday during a minor-major magnetic

	storm (accompanied by nice aurora the nights before), this is

	STRONG daytime auroral chorus rarely heard at lower latitudes.

	Recorded up the Steese Highway about 40 miles northeast

	of Fairbanks, AK on 06 Sept. 1995 at approx. 2045 UTC.

	(approx. 85 secs.)
