Using observations by SoHO and Wind, which have been at various 
locations in the Solar Wind since 1995, we have made a study of 
correlations between density and flux over seven years during solar 
cycle 23.  In this talk various results of the work will be 
discussed.  Most of the work has been done using a time base of one 
hour to compile distribution functions of correlation coefficients 
covering months and years.  The resolution of the data from which the 
coefficients are derived is 96s.

One interesting result is that the distribution of correlation 
coefficients can be divided into two parts, one containing 
discontinuities and shocks, and the other probably due to random 
coincident fluctuations.
