In the DEOS project three sounding rockets (F05-F07) have been launched from SHAR, South India, into the equatorial ionopshere in April and September 1998. Each payload was equipped with two Langmuir probes, an impedance probe, a resonance cone probe, and a radio beacon instrument. These instruments allow independent measurements of electron temperature, density, and density fluctuations. Here we present the analysis of the density fluctuations from flight F06. During this flight the bottomside ionosphere was perturbed by equatorial Spread F. After 212 s flighttime, close to apogee, the rocket left the perturbed region and a smooth nighttime density profile was found on the downleg. Density fluctuations were measured with a fixed bias Langmuir probe and the results are compared with the density profile measured by a swept Langmuir probe and an impedance probe. Enhanced fluctuations are observed mostly in conjunction with density depletions. The largest density cavity is found with a low degree of fluctuations. The power spectra are analyzed with reference to show a significant power-law behavior. Inside the perturbed region a zone with absense of turbulence is recognized. These results are compared with earlier findings of other authors.
