                         periods, mainly from the Brazilian and Asian longitude sectors are 
                         analysed in this paper. Ionosonde magnetometer and Ionosphere 
                         Electron Content (IEC) data from the EITS-1 and -2 campaigns 
                         (during March and December 1991) are complemented by 
                         interplanetary magnetic field and some ground based data sets from 
                         other campaigns. The analysis focuses on the response of the 
                         equatorial ionospheric heights and ionizaton anomaly to 
                         disturbance electric fields, identified as a direct penetration 
                         electric field associated with IMF B, changes and development of 
                         the ring current (especially the asymmetric component), and that 
                         produced by a disturbance zonal neutral wind. New evidence on the 
                         local time and longitudinal dependences of these electric fields 
                         constitute the main results of this paper. Especially, a large 
                         eastward electric field (associated with the asymmetric ring 
                         current) in the dusk-dawn sector causes significant expansion of 
                         the EIA in this sector, and amplification of the evening preversal 
                         uplift of the F-layer over Brazil. Significant inhibition of the 
                         evening prereversal electric field enhancement seems to be 
                         produced by the disturbance zonal wind associated with the 
                         magnetic disturbances prevailing several hours earlier. Some 
                         tentative evidence on the Brazilian dusk sector disturbance field 
                         being larger than that of the Asian dusk sector support the 
                         existence of a longitude asymmetry in the intensity of the 
                         disturbance electric field.",
