Abstract:

Data is presented for parachute-borne blunt probe, charged particle, conductivity measurements during a PCA, covering a night-sunrise-day sequence of four shots on November 3, 1969 at Ft. Churchill, Manitoba. The measured conductivities show that the effects of the PCA on ionization persists down to about 30 km. A description of the propagation experiment flown with the blunt probe is presented. Author
