                         of the OI 630.0 nm and OI 777.4 nm nightglow emissions are being

                         Astrofisica (LNA)'', Brazopolis (22.5 degrees S, 45.6 degrees W; 
                         dip latitude 17.5 degrees S; altitude 1860 m), Brazil, since 
                         September 2002. The all-sky imaging observations of the OI 630.0 
                         nm and OI 777.4 nm emissions, which arise from the dissociative 
                         recombination of O-2(+) ions and radiative recombination of O+ 
                         ions ( mainly), respectively, are used to monitor the morphology 
                         and dynamics of the equatorial F-region at the respective emission 
                         heights. In this paper we present and discuss the first 
                         observations showing detached equatorial F-region plasma 
                         depletions or bubbles. Three cases are presented from observations 
                         during the years 2002 and 2003. We suggest a possible mechanism 
                         for their generation.",
