Abstract : The report describes briefly results of the projects which had been carried out in assisting the airborne operation of the AFCRL Flying Laboratory. The authors analyzed most of all-sky photographs and some ionograms taken during the flights and ground magnetic records from auroral zone stations for all the flight periods, and have confirmed the existence of a circum-polar oval band of auroras, the auroral oval and the associated ionospheric structure during both quiet and distrubed periods (substorm periods).
