Abstract : We used Poynting fluxes and densities rho to investigate the stormtime thermosphere on November 10, 2004. Thermospheric energy E(sub th), which is derived from rho, consists of two sources, solar ultraviolet radiation (E(sub rh uv)) and the solar wind (E(sub th sw)). Responses of E(sub th) to interplanetary driving suggest that the thermosphere can be described by the equation dE(sub th sw/dt = alpha epsilon - (E(sub th sw/tau)), where epsilon (sub vs( represents the electric field; alpha and Tau are constants. We show that: (1) E(sub th sw) is three times the ring-current energy; (2) alpha epsilon is comparable with model predictions; (3) signatures of equatorward propagating disturbances were detected in neutral density profiles.
