Description
Summary:Measurements of power line radiation were carried out in northern Europe by means of balloon B_<15>-1N. The balloon was launched during the period of magnetic substorm on March 20,1982. Relationship between the power line radiation and a magnetic substorm was investigated by the use of magnetic field intensity spectra up to 1kHz. It revealed that the power line radiation at the fundamental frequency of 50Hz is not enhanced, but, the harmonic frequencies at 300Hz (6th), 450Hz (9th) and 600Hz (12th) are enhanced in association with the magnetic substorm.
