Abstract
Magnetic field and plasma observations from magnetotail passes of the AMPTE /IRM satellite are used to study the low-frequency magnetic fluctuation ene rgy density as a function of several local plasma parameters. Two statistic al constraints on this quantity are found, one a function of proton pressur e, one a function of proton flow speed, suggesting that ion-driven electrom agnetic instabilities may contribute to the observed fluctuations.
