Abstract : The variations of the magnetic field from lightning discharges within the vicinity region, up to 20 km from the lightning paths, were investigated during the thunderstorm seasons of 1956-57 at four field stations outside Uppsala. A description of instrumental equipment, field stations, and investigation methods is given. The change in the magnetic field variation with the distance from the lightning path is discussed. A statistical analysis of front variations and time intervals between multiple strokes was carried out. The results were limited to available data for 1956. Different aspects of daylight photographs are discussed. A survey of the obtained research material and its treatment is presented for the contract period.
