The large-scale fluctuations of the bulk speed at 1 AU near solar maximum, from day 1 through day 365, 1979 exhibit multifractal scaling over the range from 8 hours to 2.7 days. The observations are consistent with the binomial cascade model of intermittent turbulence proposed by Meneveau and Sreenivasan (1987a). The intermittency exponent computed from these observations is &mgr;=0.19¿0.02, which is consistent with the best estimate &mgr;=0.025¿0.05 obtained from earth-based measurements of intermittent turbulence (Sreenivasan and Kailasnath, 1993). Thus the complicated speed fluctuations observed over this range of periods at 1 AU near solar maximum are described by a simple relation for the inertial range of intermittent turbulence. The multifractal structure of these fluctuations differs from that associated with the large-scale fluctuations observed during 1974 when corotating streams were dominant. In both cases the distribution of speed differences was exponential. There appears to be a solar cycle variation in the spectral exponent describing the large-scale speed fluctuations. ¿ American Geophysical Union 1993
