                         presented here were taken from March, 2013 to June 2014. During 
                         this period, the all-sky images showed 18 fast events of SSL that 
                         were seen for about 10 minutes through the images in the NaD 589 
                         nm emission. A fundamental question with respect to SSL is whether 
                         they represent additional sodium, or whether they are the result 
                         of a redistribution of the regular layer. In this study, important

                         Plain-language Summary The present study are the rarely reported 
                         observations of sporadic sodium layer (SSL) detected by an all-sky 
                         system with a narrow sodium filter, operating at Cachoeira 
                         Paulista (22.7° S, 45.0° W) and lidar observations of the 
                         mesospheric sodium layer, operating at S{\~a}o Jos{\'e} dos 
                         Campos (23.1° S, 45.9° W), both observatories in Brazil. The 
                         all-sky images events and sodium data presented here were taken 
                         from March, 2013 to June 2014. During this period, the all-sky 
                         images showed 18 fast events of SSL that were seen for about 10 
                         minutes through the images in the NaD 589 nm emission. A 
                         fundamental question with respect to SSL is whether they represent 
                         additional sodium, or whether they are the result of a 
                         redistribution of the regular layer. In this study, important 
                         features from these observations are presented and discussed.",
