Abstract : Operation PCA 69 was a coordinated rocket, satellite, aircraft and ground measurement program designed to study the physical chemistry of the ionospheric D-region in conjunction with an by means of a solar proton event. During the event of 2 November l969 a total of 36 rockets were launched at Churchill, Canada over a two-day period in coordinated series for the measurement of various atmospheric parameters with emphasis on the night-day variations, but including measurements during the transition periods of sunrise and sunset. In addition, 11 rockets were launched to provide certification and background information. Electron and proton flux measurements were made on several satellites. Ground measurements including 30 MHz riometers, magnetometer, ionosonde, and partial reflection experiments were made at Churchill during the period, and aircraft optical measurements were made on 2 November l969. A conference was held at Boston College, Massachusetts on 31 March and 1 April 1970 to assess the quantity and quality of the data. Preliminary results are presented either as papers or summaries.
