Abstract : With a view to studying the structure and dynamics of the interplanetary medium, a three-station interplanetary scintillation (IPS) observatory is being developed in India. Operating with only half the aperture (approx. 2500 sq m) at a frequency of 103 MHz, the first IPS telescope at Thaltej near Ahmedabad is making daily observations of 8-10 radio sources. Parameters of the intensity pattern, such as scintillation index, autocorrelation, temporal power spectrum, moments of intensity etc., are computed. With a two-parameter curve-fitting method it is found that the IPS power spectra are best matched with an exponential law. (Author)
