                         (3), mesospheric fronts were observed over Cachoeira Paulista 
                         (23\◦S, 45\◦W) using an all-sky airglow imager. 
                         Images of OH, Na, O2(0,1) and OI557.7 nm airglow emissions were 
                         collected during the nights of observation. The mesospheric bores 
                         were found to be rear events as they were only observed thrice 
                         within a span of two years. The observed fronts were undular and a 
                         non-undular bore with dark fronts only. These suggest the absence 
                         of complimentary images which indicate that the bore would be 
                         centered below the airglow emission layers as proposed by Dewan 
                         and Picard, 1998. The fronts propagated from SW-NE for (1) and 
                         NW-SE for (2 \& 3), dividing the sky into bright and dark halves. 
                         These events could also occur as a result of a sudden change in 
                         the normal temperature profile of the atmosphere. As a result of 
                         this, the background of the atmosphere was studied using LIDAR 
                         data measured at Sao Jos´e dos Campos (23.2\◦S, 
                         46\◦W) so as to detect this abrupt change in temperature.",
