Determining lightning polarity (positive or negative) by raw signal processing?

Data from the european lightning detection network EUKLID could be correlated with this ligthning, it was a very strong negative lightning with -144 kA strength. The E field channel (magenta trace) goes POSITIVE in the first peak of the signal, so this is the signature for negative CG lightning. Positive CG lightning will first go negative in the E field channel.

That would be an interesting observation... if it proves consistent. Using the attached correlation E with Channel C ...(E signal in phase with A and B, trust me,)  which of the following random "sferics" might be "Positive" sferics? Rolleyes Why?  (Just assume they're all strokes, not junk)...
