WHISTLERS OBSERVED AT GEOMAGNETIC LATITUDE 7.04°N IN JANUARY, 1982

<正> The data of whistlers in low latitudes are of great significance for studying the mechanism of their formation and propagation. In the study of whistlers observed on ground in low latitudes, the question as to at how low a latitude the whistlers can no longer be received, namely, the question of low-latitude cut-off, is interesting. So far as we know, up to 1980, the lowest geomagnetic latitude where whistlers were recorded is 12.9°N. Besides, research workers from Wuhan University received whistlers at Zhanjiang in December, 1980. We also received whistlers at Puzai, Zhanjiang (geomag-
