                         thermosphere (MLT) airglow OI5577, O(2)b(0,1) and OH( 6,2) 
                         emissions and OH rotational temperature have been observed at 
                         Cariri airglow observatory (7.4 degrees S,36.5 degrees W) within a 
                         distance of approximately 1000 km to the east of Sao Luis. Both 
                         observation sites are located in the equatorial region of South 
                         America. Spectral analyses of the ionospheric F-layer bottom 
                         height (h'F) and airglow emission intensity reveal that there are 
                         quasi 2- and 4-day period oscillations in their temporal 
                         variations. This might indicate that planetary scale oscillations,

                         Kelvin waves, are present in the ionosphere. This is the first 
                         time that the planetary scale waves in the MLT region and in the 
                         ionosphere are discussed by airglow and ionospheric observations,
