                         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 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.",
