%X Since 2001, the formation of plasma bubbles observed by ionospheric airglow OI 630.0 nm and OI 577.0 nm emissions have been registered at Southern Space Observatory, located at São Martinho da Serra, RS, south of Brazil (29° S, 53° W). A photometer to monitor the zenith intensity and an all-sky imager to observe the spatial variation of the emissions were used. The observed zenith intensities showed strong seasonal variation, maxima in the equinox season (March-April and September-October) and minima in solstice (June-July and December-January). The OI 630.0 intensity depletions caused by formation of the plasma bubble along the magnetic field line were detected by the imager. The depletions were observed more frequently in the period from September to March during the summer season in Southern Hemisphere.
