Abstract
Two consecutive mesospheric bores were observed simultaneously by two all sky cameras on 19 December 2006. The observations were carried out in the Northeast of Brazil at two different stations: São João do Cariri (36.5 deg. W; 7.4 deg. S) and Monteiro (37.1 deg. W; 7.9 deg. S), which are by about 85 km apart. The mesospheric bores were observed within an interval of ~3 hours in the NIR OH and OI557.7 nm airglow emissions. Both bores propagated to the east and showed similar characteristics. However, the first one (left side) exhibited a dark leading front with several trailing waves behind and progressed into a brighter airglow region. While, the second bore (right side), observed in the OH layer (bottom), comprised of several bright waves propagating into a darker airglow region.
