Overhead ionospheric incoherent scatter radar data from Millstone Hill are used here to deduce the stormtime variations of the thermospheric temperature, O and N2 densities, and F1 region ion composition during the Equinox Transition Study of September 17-24, 1984. The observed neutral temperature T(n) enhancements on the magnetically disturbed days are found to be so large that they lead to the deduction of very large depletions in both the O and N2 densities in the lower thermosphere on these days. Use of the MSIS-86 model T(n) enhancements instead of the measured ones produces much smaller but still substantial (O) depletions and (N2) variations largely consistent with the effects of thermal expansion. F2 region ion composition derived from the data, compared with the height of the peak ionospheric density, shows that the latter was sometimes down in the molecular-ion rather than the atomic-ion portion of the F region.
