Abstract. On 1 October 2005, during the SpreadFEx campaign, a distinct mesospheric bore was observed over São João do Cariri (7.4° S, 36.5° W), Brazil by using airglow all-sky imagers. The event appeared both in the OI5577 and OH emissions, forming a well extended wave front which was followed by short waves from behind. Simultaneous wind and temperature data obtained by the meteor radar and the TIMED/SABER satellite instrument revealed that the bore event occurred during the Doppler ducting condition in the emission layers.
