Auroral Chorus Recording (Paul Nicholson)

If you missed the streamed natural VLF auroral chorus emissions the other morning here is a nice recording made by Paul Nicholson in Todmorden UK.  It is a truly unbelievable sound, produced not by birds but by the auroral electromagnetic activity at VLF.

VLF Chorus audible in UK this morning

Auroral Chorus, a natural VLF emission that sounds like birdsong is audible in the UK this (early) morning. It is still audible at 0650z. Check out the VLF natural radio receiver at http://abelian.org/vlf/test.html as soon as possible, as it will soon be gone.
