✦ Synopsis

Observations of whistlers during quiet times made at low-latitude ground station Nainital (geomag. lat. 19" 1' N) are used to deduce plasmasphero-ionosphere coupling fluxes. The whistler data from 3 magnetically quiet days are presented that show a smooth decrease in dispersion with time. This decrease in dispersion is interpreted in terms of a corresponding decrease in electron content of tubes of ionization. The electron densities, electron tube contents (1016 el/m2-tube) and coupling fluxes (10 el m-l sT2) are computed by means of an accurate curve fittingmcthod developed by Tarcsai (1975) and are in good agreement with the results reported by other workers.
