Observations of streamer formation in sprites


Optical imaging using a 10,000 frames per second high speed camerashows (Geophysical Research Lett. Vol.34 (2007)) that sprites are actually clusters of small, decameter-sized (10-100 m, 30-300 ft) balls of ionization that move downward, followed a few milliseconds later by a separate set of upward moving balls of ionization, and traveling up to ten percent of the speed of light.

Things not found on Wikipedia

While most of this blog won't be found on Wikipedia (actually not any of it) that didn't stop me from starting a blog about things not found on Wikipedia.

Mostly for fun, does not fall into the evidence based science realm.

The blog Evidence based medicine might.
