| Abstract: | A plasma irregularities spectrum analyzer and a Langmuir probe experiment on a rocket experiment conducted at mid-latitudes during quiet night-time winter conditions revealed the existence of an isolated plasma density depletion between 700 and 1100 km. A substantial enhancement of intensity of the irregularities coinciding with the depletion was observed over a broad band of irregularity sizes ranging from tens of meters to several kilometers. The power spectral index was equal 0.84∓0.17 as compared to 1.71∓0.56 for the irregularities outside the plasma depletion. |
