Interplanetary Scintillation — Preliminary Observations at 103 MHz
A 3-station interplanetary scintillation (IPS) observatory is being developed mainly with a view to study the solar wind plasma. The first IPS telescope operating at 103 MHz at Thaltej near Ahmedabad has been put into regular operation since April 1979. With only half the antenna aperture (∼2500 m2) presently in use, observations of 8–10 sources are being made to calculate scintillation index, temporal spectrum of intensity fluctuations and scale size of density irregularities.
