                         two all-sky cameras on 19 December 2006. The observations were 
                         carried out in the northeast of Brazil at two different stations: 
                         Sa{\~o} Joa{\~o} do Cariri (36.5  W, 7.4  S) and Monteiro 
                         (37.1  W, 7.9 deg; S), which are by about 85 km apart. The 
                         mesospheric bores were observed within an interval of \∼3h 
                         in the NIR OH and OI557.7 nm airglow emissions. Both bores 
                         propagated to the east and showed similar characteristics. 
                         However, the first one exhibited a dark leading front with several 
                         trailing waves behind and progressed into a brighter airglow 
                         region, while the second bore, observed in the OH layer, was 
                         comprised of several bright waves propagating into a darker 
                         airglow region. This is the first paper to report events like 
                         these, called twin mesospheric bores. The background of the 
                         atmosphere during the occurrence of these events was studied by 
                         considering the temperature profiles from the TIMED/SABER 
                         satellite and wind from a meteor radar.",
