The origin of micro Comets and Ball lightning.
(What goes DOWN sometimes goes UP)
25 years ago during heavy thunderstorm in the Netherlands, a photo camera with automatic shutter recorded strange bead lightning streaks with interesting curvature.
At the end of some streaks a fire ball was visible.
Reconstruction of the curvature of the bead lightning suggested that all the streaks should have some relation to each other and the same frequency.

Could it be, that electromagnetic wave interference (with the same wavelength) was responsible for this phenomenon?
The answer was YES if there was also an x-ray (or Gamma-ray) component into play.
Why do we need this x-ray phenomenon? Because not all lightning strokes produce bead lightning or fireball ball lightning.
There must be some irregular component responsible for the incidental emerging of Ball lightning and Bead lightning.
This component could be found in the recent experiment results of professor J.R.Dwyer, ( Geospace physics lab,FIT). He discovered the x-rays emission from laboratory sparks and lightning strokes.
(see: The observation of x-ray bursts produced by 1.5 MV laboratory sparks in air

Recently also M.Rahman (Upsala university Sweden) made comparable experiments: “x-rays from 80 cm long sparks in air” with x-ray emission results, see:

However, if strong electromagnetic radiation and accompanying x-rays are responsible for ball lightning, then perhaps also (larger) ball lightning effects could be found in space at places with high discharge energies like so called SPRITES and ELVES or even near the solar surface by so called BIRKELAND currents.
Judge for yourselves and look at the slow-motion video of Langmuir University of sprites and elves. See under: “Sprites and Elves as the origin of small Comets and large Ball Lightnings”

What you see is the production of lots of fireballs going down and partly after a while going up again!!! Just like the solar photo presenting at least four fireballs going down and ONE going upwards!!
