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.
