                         data collected from the low-latitude network of ionosondes and 
                         magnetometers operated at different longitude sectors of the globe 
                         as a part of the SUNDIAL 86 campaign (22 September to 3 October, 
                         1986). Based on case studies of EIA developments, attention is 
                         focused on identifying the EIA response to changes in the electric 
                         fields associated with the equatorial electrojet and counter 
                         electrojet events. The response time of the EIA to electric field 
                         changes is found to vary from 2.5 to 4 h. An anomalous EIA 
                         development observed in the morning sector on September 23 
                         suggested possible electric field penetration to low latitude 
                         during a substorm energy storage/Dst development phase. The 
                         analysis also shows that the afternoon EIA could be inhibited due 
                         to equatorward blowing disturbed neutral winds. The results of the 
                         present analysis emphasize the need for pursuing further 
                         investigations for the response of EIA to magnetosphere-induced 
                         disturbances.",
