                         emissions have been made from Bear Lake (BLO) Observatory, Utah 
                         (41.6° N, 111.6°W).The image data were obtained over a 2-year 
                         period (2002-2003) have been used to investigate the occurrence 
                         and properties of undular mesospheric bore events. It was detected 
                         about 130 events like mesospheric bore during this observation 
                         period. The complementary effect determined by the Dewan and 
                         Picard model (1998) for the airglow images (OH, O2 e OI557) can be 
                         classified in four categories: Brighter Brighter Brighter (BBB), 
                         Brighter Brighter Darker (BBD), Brighter Darker Darker (BDD) and 
                         Darker Darker Darker (DDD). The BDD effect was most common at Bear 
                         Lake (~35%), in this case the bore height is below the OI5577 and 
                         O2 layers but above the OH layer. The bore events characteristics 
                         retrieved from the image data for BLO also are compared whit 
                         results of the low latitude.",
