dc.description.abstract	During 13th Indian Scientific Expedition to Antarctica (ISEA) (1993-95), the dependency of high frequency (HF) radio links at 16.94 MHz, 14.45MHz and 17.425 MHz operated between India and Antarctica, on degree of geomagnetic disturbance was studied. The data was collected from Jan. 1994 to Dec. 1994. Earlier observations carried out over 1992 (JEEVA et al. 1994) during the 11th ISEA, showed good correspondence between HF communication and the quietness of the electromagnetic environment of the Earth. In contrast to this during 1994, though there was in general, good correspondence between HF signal strength and level of magnetic quietness, on certain days no correlation was found. We try to explain some of these observations and anomalies in this report.	en_US
