ULF Measurements

Abstract

The report describes the results of an experiment to investigate the possibility of artificially stimulating ultra-low-frequency (ULF) signals in the earth's magnetosphere by means of signals from a very-low-frequency (VLF) transmitter. A VLF transmitter system was operated near Anchorage, Alaska, in August and September, 1973. The investigator operated a low-frequency (0.1 - 45 Hz) portable magnetometer station at a site adjacent to the VLF transmitter, and also designed a schedule of modulation modes and transmission frequencies for the VLF transmitter in an effort to cause stimulation of ULF signals which would in turn be detected by the magnetometer.
