High speed camera sees lightning streamer formation

Pictures du jour here.
Forum rules
This is a good place to put pix of your lab or shop intended to produce the drool reaction. If topics get lengthy here, we may want to move most of the discussion to where it fits in the org scheme here (such as it is). Good place for announcements of things you just got working and so on. Respecting readers who may not have large bandwidth, try and keep the pictures to about one megapixel -- we have the BW and the storage here, no problems, but some readers may not.

I just thought this one was cool. This is why above about 50kv it gets real hard to handle high voltage in air - you get these streamers due to enough field concentration at their points to ionize the air in front of them, and the spark length can then be almost infinite.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
