Equatorial Plasma Bubbles

Plasma bubbles are irregularities in the ionospheric F layer, which are generated by the Rayleigh-Taylor instability in the low latitudes. Those structures extend several kilmeters along the magnetic field lines, can have several kilomenters of width and grow upward into the ionosphere up to thousand kilometers.

Equatorial Plasma Bubble (EPB) have been observed over São João do Cariri using OI6300 airglow images, which allow us investigate the dynamics and temporal variability.
