                         preliminary statistics of airglow observations performed per 
                         all-sky imager between 2017 and 2020, from the Observat{\'o}rio 
                         Espacial do Sul (OES/COESU/INPEMCTI), will be presented. With this 
                         instrument we can observe atmospheric gravity waves (AGWs), 
                         mechanical oscillations generated by the imbalance between the 
                         forces of gravity and the pressure gradient. Based on preliminary 
                         visual analysis of the nighttime airglow observations, the nights 
                         conducive to the identification of AGWs events were quantified, 
                         classifying them as useful and useless, according to 
                         pre-established criteria, such as sky visibility, light 
                         contamination and duration of observations. So far, 1.063 nights 
                         have been observed, of which 410 were classified as useful and 653 
                         as useless. A total of 6.708 hours of observations were recorded, 
                         2.995 of which were suitable for the identification of AGWs 
                         events, that is 44,64% of the observed hours. The observations 
                         from the years 2021 and 2022 will still be analyzed, so that a 
                         detailed study can be carried out.",
