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.",
