From 1 January, 1983 to 30 March, 1983 the ISEE‐3 spacecraft was in the region of the magnetotail of the earth at distances from 60 to 240 R E . The ion composition instrument aboard ISSE‐3 made ion composition and velocity measurements in two modes during this period. In the first mode the mass per charge (M/Q) range was 0.7 to 32 at velocities from 79 to 220 km s −1 . The M/Q range of the second mode was 1.4 to 6.0 at velocities from 300 to 620 km s −1 . Preliminary analysis of the data shows the magnetotail composition to have a significant solar wind‐like component, with bulk velocities generally in the 300‐600 km s −1 range.
