I am beginning another phase of VLF/ELF nightly meteor (and transient luminous event) observation. My last year long VLF/ELF campaign was in 2009.

Monitoring VLF/ELF in conjunction with VHF scatter is really helpful
because often there is ionization evident at VHF just before the meteor
becomes visible as light on camera.

Here is a meteor from this morning, Mar 15, 2012. This particular meteor goes into the inconclusive direct VLF/ELF emission
category but maybe there will be a clear pattern that will develop over time.

I am waiting for much larger meteors with mid-flight flaring and
terminal bursting. Here is the best specimen from my last VLF/ELF campaign:
