| Resumo | Using ground-based measurements we investigate the occurrence of dark band structures in the OI 630 nm nightglow emission all-sky images in the Brazilian low latitudes region during the periods from January 1990 to December 1990 and from January 2000 to December 2000 (high solar activity period; average 10.7 cm solar cycle flux > 180x10−22Wm−2Hz−1 ), January 1995 to December 1996 (low solar activity period; average 10.7cm solar cycle flux < 90x10−22Wm−2Hz−1 ) and from January 1997 to December 1999 (ascending solar activity period; average 10.7 cm solar cycle flux from130x10−22Wm−2Hz−1 to170x10−22Wm−2Hz−1 ). The OI 630 nm images obtained during these periods show thermospheric Dark Band Structures (DBS) in low latitudes region propagating from southeast to northwest. These dark patches moved with average speed of about 80-250 m/s at an altitude of 220-300 km, which is the typical altitude range of the OI 630.0 nm airglow emission. Also, digisonde observations registered abrupt increases in both the F-layer peak height (hmF2) and base height (hF) when the low intensity band passed over Cachoeira Paulista. During the period studied a strong solar cycle and seasonal variations were noticed in the DBS. Only during low solar activity period (LSA) and ascending solar activity period (ASA) the DBS occurrences were observed in the OI630 nm nightglow emission all-sky images. It should be pointed out that these thermospheric/ionospheric events are not related to geomagnetic disturbed conditions. In this paper we present important features from these set of observations in the nighttime thermosphere/ionosphere under different solar activity conditions. A possible mechanism for generation of these dark band structures is presented. |
