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...
