Abstract

Some experiments on June 8, 2004, the day of transit of Venus across the Sun, were undertaken at Kolkata (latitude:
22°34lN) to observe the effect, if any, of transit of Venus on FWF, ELF and VLF amplitudes. The result
shows a good correlation between their temporal variations during the transit. The observation was unbelievable
as the Venus subtends only 1/32th of the cone subtended by Sun on Earth. This anomaly may be explained on
the assumption that the height of Venusian atmosphere with high content of CO2, and nitrogen which absorbs
electromagnetic and corpuscular radiations from Sun, depleting the solar radiation reaching the Earth to a considerable
extent. As a result, relevant parameters of Earths atmosphere are modulated and here we show how
these changes are reflected in identical behaviour of fair weather field and ELF and VLF spectra.
