                         Brazil. This technique permits observations covering a large area,

                         this observational site. During February 1995, a relatively good 
                         sequence of observations on six consecutive nights were obtained. 
                         On five out of the six nights, weak to strong nearly north-south 
                         aligned intensity depleted regions, which are the optical

                         depletions, were observed. Important features from this set of 
                         observations, including vertical and zonal velocities of the 
                         plasma bubbles, are presented and discussed in this paper.",
