Whistler-triggered VLF emission recorded at low latitude ground station Jammu (Geomagnetic Latitude = 220 26/ N, L = 1.17) are reported. The dynamic spectrums of whistler-triggered emissions based on spectral analysis have been carried out. The riser triggered from the bottom side of the whistler spectrum. According to Smirnova theory, the L – value of rising emissions have been computed. An attempt is made to explain the generation and propagation mechanism of these emissions.
