The association between energetic protons (0.29--0.50 MeV) and simultaneous local fluctuations of magnetic field at 35 to 45 R/sub E/ in the magnetotail is examined statistically with data from APL/JHU particle telescopes aboard IMP 7 and IMP 8. About four satellite years of 5.5 min averaged measurements are used in this study. In addition to confirming that the level of magnetic field fluctuations generally increases with the presence of energetic protons and their streaming anisotropy, it is found that increase in occurrence frequency of streaming of energetic protons are ordered far better by magnetic field fluctuations (deltaB>5nT or deltaB/B>50%) is neither a neccessary nor a sufficient condition for the detection of large streaming in energetic protons.
