The local RACES (look it up) net sometimes asks for 'green flashes not associated with lightning'.
Well Duh... even cooks with ham radio licenses know that copper oxidizes to a green color.
White flash? Lightning (or a nuke, and if that's the case, there are other problems). Greenish flash (you will know in the afterimage, once you've seen one) is probably a transformer.
The oil coming out of busted and burned transformers isn't particularly something you want to roll around in, either. Run away works for that.
Difference between a storm spotter and a storm chaser is 50 IQ points. ;)

Well, I don’t see much green. There is some blue in the fringing around explosions themselves, but not in the explosions as they decay. There’s no evidence of lightning that I can see, although it might have earlier initiated the (multiple) explosions. I’ve seen other vids of what were definitely transformers blowing up, with no green (and some with). So, I don’t know. Maybe it’s a limitation of the CCD’s in the video cams? Or my eyes. :-)
Have you watched the vid?
Note: It’s up to over 5.5 million views already. Sheesh.
