| Abstract: | Whistlers recorded at Varanasi (geomag. lat. 14°55'N) during the period Jan. 1976-Aug. 1978 have been analysed. It is shown that the nighttime whistlers are characterized by extremely small dispersion of less than 15 s1/2. This feature supports the hypothesis of combined ground-ionosphere waveguide and field-aligned propagation known as hybrid mode of propagation. The lower cut-off frequencies of these whistlers have been evaluated and majority of these whistlers are found to lie in the low frequency range of 1.7-3.4 kHz. |
