Synchronized whistlers recorded at Varanasi

摘要

Some interesting events of synchronized whistlers recorded at low latitude station Varanasi during magnetic storm period of the year 1977 are presented. The dynamic spectrum analysis shows that the component whistlers are Eckersley whistlers having dispersion 10 s1/2 and 30 s1/2. An attempt has been made to explain the dynamic spectra using lightning discharge generated from magnetospheric sources Keywords Whistler-mode wave propagation - dispersion - synchronized whistler PACSNo 94.20.Mm
