| Abstract: | Atmospherics activity at 5 kHz, observed during the southern summer at San Miguel, Argentina, is presented. Data are available for all directions of incidence during the time span of this investigation.The activity shows a pronounced variation from day-to-day. A spectral analysis of these data with an autocovariance function and the related power spectrum yields enhanced spectral contributions with periods at 2.4 and 7.5 days. An additional smaller peak in the power spectrum was also observed at a period of 4.7 days. These periods have the same time scale as planetary waves. |
