A COSPAR-sponsored Symposium on Solar Particle Events 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 Proton Event. This particular event was unique in that extensive solar, magnetospheric and aeronomic measurements by rocket, satellite and ground based techniques were made to provide a comprehensive picture of the phenomenology and morphology of this event. In addition, present knowledge of solar proton events and their effects on the polar ionosphere was reviewed and discussed. This included theoretical studies as well as results from investigations of other solar proton events. The symposium comprised invited as well as contributed papers. A total of 49 papers presented at the symposium are included in these proceedings.

In this report, an atmospheric model for the calculation of riometer absorption during Polar cap absorption events is given; specifically, an atmospheric response function is calculated and tabulated at necessary altitudes for (1) each month of the year, (2) day and night, and (3) 60 degrees N and 90 degrees N latitude. In addition, a polynomial fit to the atmospheric response function is given in terms of polynomial coefficients. Also tabulated for the conditions above are the collision frequency, atmospheric depth, and scale height.

Electromagnetic wave absorption was measured at several frequencies as a function of altitude for six rocket flights during the 2 to 5 November 1969 Solar Proton Event (SPE). Meaningful data were obtained at 36 MHz, 18 Mhz, and 9 MHz for four of these flights. These data and 30 MHz riometer data are shown to be in excellent accord with the calculated absorption. The agreement provides further support for the accuracy claimed for the electron concentrations that were measured simultaneously by means of dispersive phase techniques. It is stressed that uncertainties in the pressure are probably the largest error source. The electromagnetic wave absorption apparently was uneffected by the SPE-disturbed D-region except for the enhanced electron concentration. (Author).

D-region ionization rates have been determined from satellite proton spectra as a function of altitude for forty-four instances during the period of 2 to 5 November 1969 Polar Cap Absorption Event. The ionization rates were calculated using least square fits to the satellite proton spectra in both energy and rigidity. The combined results provide ionization rates for the event as a function of universal time. (Author).
