This Video Shows a Zoom-In on the Positively Charged Lightning Channel (VIDEO)
Caption
The video shows a zoom-in on the positively charged channel. In real time, the development takes only 0.1 seconds and spans a distance of about 400 meters. Initially, there is little activity along the channel: it is barely visible. Only at 0:10 seconds does one see the needles develop. One particularly large needle is depicted in red. Multiple needles can be seen along the lightning channel, with each one, including the red one, 'lighting up' multiple times. At 0:20 seconds, the activity in this part of the channel stops, with some activity remaining at more distant points along the channel.
