Abstract
More than 135 passes of Viking S-X doppler data have been used to investigate the solar wind turbulence from 3 August to 15 December 1976. The results of this analysis are compared to previous investigations using Mariner DRVID data to attempt to find the changes in the turbulence over the sunspot cycle. It is found that: (1) electron density fluctuations decline with heliocentric distance as r~1-8*9-2; (2) the level of the turbulence may be a factor 2 lower near sunspot minimum than at maximum; and (3) the spectrum of the fluctuations may be steeper (~ -3.0 vs ~- 2.6) near sunspot minimum. The expected range error for various time scales and geometries is derived from the results.
