For me almost unbelivable that it is a recorded electromagnetic wave? It rather sounds as if someone who walks through the primeval forest with a microphone and a recorder and sometimes steps on a stick. Some birds in the background (1000s) and some water drops that drops on the wet bottom and gras :-) Very interesting, tnx! 73, Stefan/DK7FC Am 07.04.2010 00:57, schrieb Paul Nicholson: > Here are some highlights from the aurora 2010-04-06, > all mp3 mono 64kbps 32k samples/sec, H-field N/S loop, > Todmorden, UK. > > File 'f' is probably the best if you only want to download > one. > > 05:47:30 UT, 9:24, 4.5Mbyte > http://67.207.143.181/aur100406c.mp3 > > 05:57:05 UT, 4:20, 2Mbyte > http://67.207.143.181/aur100406d.mp3 > > 06:01:42 UT, 22:18, 10.7Mbyte > http://67.207.143.181/aur100406e.mp3 > > 06:35:35 UT, 18:15, 8.7Mbyte > http://67.207.143.181/aur100406f.mp3 > > 06:56:00 UT, 22:35, 10.8Mbyte > http://67.207.143.181/aur100406g.mp3 > -- > Paul Nicholson > --
