Continuous recording of a subionospheric transmitted signal at 16.4 kHz from Novik, Norway (66° 58′ N, 13° 54′ E) is being carried out in Kolkata (22° 34′ N, 88° 30′ E). The effects of recent solar eclipse on August 1, 2008 over this transmitted signal have been reported in this paper. The variations of normalized amplitude of this signal and its phase retardation in the path during the solar eclipse are measured which show significant deviations from their usual values for the same period of the control days.
