                         27-28, 1987 over Cachoeira Paulista (22.7°S, 45.0°W; magnetic 
                         latitude 13.25°S, declination 20°W) showing localized plasma 
                         density enhanced by a factor of, approximately, 2 above the 
                         background level. The F-region parameters were obtained from a 
                         Digisonde 256, which provide a good idea of the ionospheric 
                         behavior during the event. On this night, geomagnetic activity was 
                         moderately disturbed with Dst > -70 nT. Complementary data was 
                         obtained from an all-sky imager operating on a routine basis at 
                         the same site. All-sky images were used to map the spatial 
                         extension and temporal location of plasma blob that showed, 
                         typically, east-west and north-south extensions of 320-350km and 
                         of 360-380km, respectively. In this paper, important features from 
                         this observation is presented and discussed.",
