Abstract : The IPS observations of the high-latitude source 3C48 are used to derive the distribution of the solar wind velocity in longitude and latitude for periods of several rotations during 1974-1979, by model calculations. The observations during 1974-1978 show the existence of the north polar high-speed (800 km/sec) region. This region extended from the pole down to 45 deg to approx 50 deg latitude for most of 1974-1977, while the region contracted up to 80 deg in 1978 and was hardly observed in early 1979. (Author)
