(meteorobs) Nice fireball but no ELF/VLF radio emission noted

(Note : Radio spectrum ELF/VLF means "extremely low frequency" and VLF 
means "very low frequency")

I have shifted my primary radio meteor practice to nightly ELF/VLF 
reception along with all sky video in the hope of capturing some sort of 
direct emission from a meteor. I am also still recording VHF forward 
scatter until the TV transmitters end analog broadcast on June 12.

Last night was my first significant fireball since February and I posted 
movies with radio reception at:

For this particular fireball I can discern no obvious ELF/VLF radio 
emission that sets itself apart from the background sferics.  It did 
produce good VHF forward scatter though.

Also, this fireball was not a Lyrid.  I haven't processed the night's 
Lyrids as yet.

Clear skies,
