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:
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.",
