(Additional Alberta June 1996 files are on Main Audio-files page)

The morning of June 2nd 1996 in northern Alberta was fabulous! This particular location has proven to be great for supurb auroral-zone natural VLF radio field-recording - both on this particular morning and also during early August 2000. This series of (2-track mono) MP3 audio files exhibit a lovely sequence of nose-whistler, chorus and wavering-tone emissions recorded 02 June 1996, beginning at about 1100 UT (0500 MDT). Other audio files of this period are on the main audio files page.

Nose whistlers are called such because spectrograms of them look like human noses - falling and rising components occur at the same time.

They're best heard in high-latitude locations within the auroral-zone. S.P. McGreevy
