dc.description.abstract	The effect of total solar eclipse of October 24, 1995 on long distance VLF radio wave propagation of 22.3 kHz from North West Cape, Australia to Calcutta is being reported here. After the commencement of the total eclipse the signal exhibited small attenuation followed by a recovery and a sudden enhancement to a value comparable to seasonal maximum. After the eclipse the signal returned to almost normal value by a sudden fall. The observation is closely related to the changes of electron density of the lower ionosphere which behaves as the upper boundary of the earth-ionosphere waveguide.	en
