Does anyone know the precise timings of the Chelyabinsk meteor strike? 
General timing was at 03:20 UTC on February 15, 2013.

When did the ionization begin? Was there a radio meteor signature 
seconds before it became visible? Are there any VHF forward scatter 
captures?

It appears that the strike was recorded very well in infrasound all 
around the globe.

Is there any evidence of the strike in ULF or ELF or VLF radio data 
anywhere in the world?

Any info welcome!  Thank you in advance.
