Artificial Ionospheric Plasma Clouds

Caption: This is a sequence of images of the glow plasma discharge produced with transmissions at the third electron gyro harmonic using the HAARP HF transmitter, Gakona, Alaska. The third harmonic artificial glow plasma clouds were obtained with HAARP using transmissions at 4.34 megahertz (MHz). The resonant frequency yielded green line (557.7 nanometer emission) with HF on November 12, 2012, between the times of 02:26:15 to 02:26:45 GMT.
