Abstract : During the course of the total solar eclipse of November 12, 1966 in Cassino, Brazil a series of four rockets were fired carrying a continuous wave, low frequency propagation experiment to measure the rate of change of magnetic field strength with altitude. From this rate electron density profiles were deduced with the aid of a computerized full-wave solution technique. From the variation of electron density with time and a continuity equation for electrons the effective recombination coefficient was obtained in the altitude range from 64 to 73 km. From the known positive ion profiles during the same eclipse the negative ion to electron density ratio was deduced and used to obtain the effective ion-ion recombination coefficient versus altitude.
