| Resumo | Ionospheric plasma irregularities associated with nighttime equatorial spread-F phenomena have been the subject of intensive experimental and theoretical investigations during recent years. Large scale plasma depletions, referred to as transequatorial bubbles or plumes, continue to attract considerable attention. The studies of ionosphere plasma irregularities assume great importance, because the irregularities degrade the radio wave signals passing through the region and, therefore, have considerable influence on the ionospheric/trans-ionospheric radio wave communications. The F-region nightglow emissions arising from ionospheric recombination processes can be used to remotely observe the dynamics of transequatorial ionospheric plasma bubbles and smaller scale plasma irregularities. In a collaborative project between the Center for Space Physics, Boston University, USA- and the National Institute for Space Research (INPE), Brazil, an all-sky imaging system was put in operation at Cachoeira Paulista (22.7 degree S, 45.0 degree W, dip latitude 15.8 degree S), in March 1987. This wide angle imaging technique provides an unique capability of permiting observations over regions covering several million square kilometers from a single observing station. Also, regular measurements of several nightglow emissions and ionospheric sounding are carried out at Cachoeira Paulista and Fortaleza (3.9 degree S, 38.4 degree W, dip latitude 3.7 degree S). A VHF electronic polarimeter was in operation at Cachoeira Paulista. This clustering of observational facilities in the Brazilian sector provided coincident and complementary observations of various upper atmospheric parameters. In this paper we present and discuss some features of the 01630.0 nm emission all-sky imaging observations carried out during the period 1987-1989. The transequatorial ionospheric plasma bubbles manifest in all-sky optical imaging observations as nearly north-south aligned intensity-depleted regions. The observed seasonal variation of the airglow depletions shows a maximum during the summer months and virtually no airglow depletions during the winter months. The case studies presented show different forms of generation and development phases of airglow depletions during the course of a night. The all-sky images also permitted the determination of the altitude-latitude extent of the plasma depleted regions and some results are presented. It has been observed that the attitudes reached by the plasma depleted flux tubes over the magnetic equator in the Brazilian sector-often exceed 2500 km. |
