Brief Description (Abstract):

To examine the behavior of the sunrise and sunset terminators, characteristics of the solar activities in the polar region and the possible seismic correlation with ionospheric anomalies a Stanford AWESOME VLF receiving system was installed at the Indian permanent Antarctic station Maitri during the 27th Indian scientific expedition to Antarctica. Almost five weeks of data was recorded successfully from several transmitters around the globe. The narrow-band signals show variation of the solar radiation and the signature of the prolonged day and night. We compare the signal of frequency 18.2 kHz with the same signal received at Kolkata, and we present simultaneous observation of the variation of the sunrise and sunset terminators. We compare the diurnal signal amplitude variation with the LWPC model.

Status: Completed

Purpose: The major objective was to study of the signal variation over very long path which is totally over the ocean.
