Abstract: At Agartala (Lat 23° N, Long 91° 24´ E), North-Eastern part of India, continuous monitoring of VLF/LF sferics and subionospheric transmitted signals are being continued since 1975. From the recording of one such subionospheric signal at 40 kHz from Japan (Lat 36° 11´ N, Long 139° 51´ E), some observed typical variations in the transmitted signal amplitude during solar flares and meteor showers will be presented in this paper.
