• Ionospheric electrodynamics

The climatology of ionospheric plasma bubbles is studied here by means of a comparison of the frequency of occurrence of the spread-F/plasma bubble events over the South American region using the images from two 01 630 nm imager systems located at the subequatorial station Sao Joao do Cariri-CA (7.4 S, 36.5W, 20 S dip) and the low-latitude station Cachoeira Paulista-CP (22.5 S, 45 W, 33 S dip) in Brazil during the years of 2004 and 2005. The results are discussed in the light of current theory and geomagnetic parameters of the two observation stations.
