Dependence of VLF wave activity at Syowa Station on the day of the week
In reference to the Sunday decrease of VLF activity observed at Siple Station, VLF wave multi-frequency channel data stored in magnetic computer tapes at Syowa Station have been analyzed for the period from July 1981 to December 1983. Using 2s sampling data, at 0.75,1.2 and 2.0kHz, a minimum for eve...
