NRL Scientists Produce Densest Artificial Ionospheric Plasma Clouds Using HAARP
snip~
U.S. Naval Research Laboratory research physicists and engineers from the Plasma Physics Division, working at the High-frequency Active Auroral Research Program (HAARP) transmitter facility, Gakona, Alaska, successfully produced a sustained high density plasma cloud in Earth's upper atmosphere.
"Previous artificial plasma density clouds have lifetimes of only ten minutes or less," said Paul Bernhardt, Ph.D., NRL Space Use and Plasma Section. "This higher density plasma 'ball' was sustained over one hour by the HAARP transmissions and was extinguished only after termination of the HAARP radio beam."

The NRL group succeeded in producing artificial plasma clouds with densities exceeding 9 x 105 electrons cm3 using HAARP transmission at the sixth harmonic of the electron cyclotron frequency.
Optical images of the artificial plasma balls show that they are turbulent with dynamically changing density structures. Electrostatic waves generated by the HAARP radio transmissions are thought to be responsible for accelerating electrons to high enough energy to produce the glow discharge in the neutral atmosphere approaching altitudes of nearly 170 kilometers.
artificial plasma clouds huh
