                         Brazilian rocket launching station in Natal. The SONDA III rocket, 
                         carrying a High Frequency Capacitance Probe (HFC) and two airglow 
                         photometers in addition to a swept voltage Langmuir Probe, was 
                         launched into an ionosphere marked by a developing plasma bubble 
                         event a 2030hrs local time on December 11, 1985. The electron 
                         density profile estimated from the LP and HFC data clearly shows 
                         the presence of two large plasma depletions or bubbles in the 
                         topside F-region centered at 370km and 430km. FFT analysis of the 
                         LP current fluctuations in the frequency range of approximately 
                         50Hz to 800Hz provided information on the spectral distribution of 
                         small scale electron density irregularities along the rocket 
                         trajectory. Small scale irregularities are observed inside the 
                         plasma bubbles in regions of downward electron density gradient 
                         indicating their possible generation by the well known crossfield 
                         instability mechanism. A brief study of the spectral features of 
                         these irregularities is reported in this paper.",
