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