The extremely low frequency and very low frequency ELF/VLF recording system was successfully installed during the 20Ih Indian Scientific Expedition and data were collected from January 12, 2001 to February 24, 2001. VLF's emissions including hiss and rising type of discrete events have been observed. Whistlers could not be detected in the partly analyzed data, although a large number of atmospherics have been observed. To explain the VLF emissions, we have considered Cherenkov radiation as the generation mechanism. To understand the generation and propagation mechanism of VLF waves at high latitudes, we record VLF waves at the Indian Antarctic Station Maitri (geogr. LAT. 70? 46 S geogr. Long. 11? 44 E). Continuous observation of very low frequency, whistlers and related phenomenon with the help of digital audio tape recorder was carried out during the 20th expedition. The data will also be used to study the coupling of ionosphere and magnetosphere. Medium parameters can also be estimated and hence the waves can be used as the diagnostic tool of the medium.
