Report Introduction

The COSPAR-sponsored Symposium on the November 1969 Solar Particle Event was held at Boston College at Chestnut Hill, Massachusetts, on 16, 17, and 18 June 1971. The purpose of the symposium was to present measurements and observations made during the November 1969 solar particle event and to review and discusspresent knowledge of solar particle events and their effects on the polar ionosphere. The November 1969 event was of particular significance because ofthe comprehensive rocket and ground measurement program called PCA-69 conducted during the event and the extensive satellite and ground experimental coverage available. Of the 49 papers presented at the Symposium, 39 were con cerned with the November 1969 event including 20 based on rocket results, 10 on ground and aircraft observations and 9 on satellite results. The Symposium pro gram was divided into 5 subject areas with an invited speaker for each. The cate gories and the session chairmen were: The Solar Proton Flare of 2 November 1969 (R. Carovillano, Boston College); Energetic Particles and Magnetospheric Effects (J. Ortner, European Space Research Organization); Ionospheric Effects (W. Ber ning, Defense Nuclear Agency and W. Pfister, Air Force Cambridge Research Lab oratories); Aeronomy Effects (C. Blank, Defense Nuclear Agency); and the Disturbed D-Region (W. Heikkila, University of Texas). These proceedings contain the papers presented at the symposium. Since the results of the program called PCA 69 are the subject of the majority ofthe papers of the proceedings, a summary of the total program is also presented inAppendix A as a reference and to provide continuity to the reader.
