                         electric field and electron density were made on 18 December, 1995 
                         at 2117 h (LT) from the equatorial station Alcantara (2.31°S; 
                         44.4°W) in Brazil, with a rocket-borne electric field double probe 
                         and two different types of electron density probes. The main 
                         objective of the experiment was to study the characteristic 
                         features of the electron density and electric field fluctuations 
                         associated with plasma bubbles. The rocket reached an apogee 
                         attitude of 557 km covering a horizontal range of 589 km. The 
                         upleg electron density profile showed the presence of a clearly 
                         defined base for the F-region around 300 km, while the downleg 
                         profile showed the presence of a wide spectrum of electric field 
                         and electron density irregularities in the entire F-region. 
                         Spectral analysis of the fluctuations in the electron density and 
                         the electric field clearly indicated the presence of sharp 
                         spectral peaks associated to each other at several heights. This 
                         is suggestive of the electrostatic nature of these E-field waves 
                         with associated plasma density fluctuations. These waves seem to 
                         extend over hundreds of kilometres in the horizontal and vertical 
                         directions. The sources of these waves are not well understood, 
                         however.",
