             abstract = "Height profiles of the ionospheric electron density and 
                         temperature were made from Brazil on different occasions under 
                         different ionospheric conditions. During one of the launches the 
                         rocket passed through welldeveloped plasma bubbles on both upleg 
                         and downleg. During the second launch the ionospheric F-region did 
                         not show the presence of prominent plasma bubbles. During the 
                         third launch the rocket on its upleg passed through an F-region 
                         without plasma bubbles while on its downleg it passed through an 
                         Fregion that showed a large number of welldeveloped plasma 
                         bubbles. Electron temperatures were estimated by applying sweep 
                         potentials to Langmuir probes. During the first and second 
                         launches the electron temperatures estimated were comparable to 
                         those given by models. But during the third launch the electron 
                         temperatures estimated showed abnormally high values of more than 
                         3000 deg. K in the lower F- region only on the rocket upleg. The 
                         maximum electron temperature observed above the F-peak was only 
                         about 700 deg. K. The region below the base of the F-region seems 
                         to be associated with very large electron temperatures just before 
                         the development of plasma bubbles. An attempt is made here to get 
                         the electron energy distribution function (EEDF) from the second 
                         derivative of the current-voltage characteristic curves.",
